I am an Assistant Professor of Computer Science at the University of Chicago. I founded and direct 3DL (threedle! ), a group of enthusiastic researchers passionate about 3D, machine learning, and visual computing. I obtained my Ph.D. in 2021 from Tel Aviv University under the supervision of Daniel Cohen-Or and Raja Giryes.

My research is focused on building artificial intelligence for 3D data, spanning the fields of computer graphics, machine learning, and computer vision. Deep learning, the most popular form of artificial intelligence, has unlocked remarkable success on structured data (such as text, images, and video), and I am interested in harnessing the potential of these techniques to enable effective operation on unstructured 3D geometric data.

We have developed a convolutional neural network designed specifically for meshes, and also explored how to learn from the internal data within a single shape (for surface reconstruction, geometric texture synthesis, and point cloud consolidation) – and I am interested in broader applications related to these areas. Additional research directions that I am aiming to explore include: intertwining human and machine-based creativity to advance our capabilities in 3D shape modeling and animation; learning with less supervision, for example to extract patterns and relationships from large shape collections; and making 3D neural networks more “interpretable/explainable”.

Project: Causality for Credible AI. The backbone of modern ML is evaluation on randomly held out data. However, models with strong held out performance frequently still exhibit disturbing failures. For example, they can degrade when deployed out of domain, learn to depend on apparently irrelevant input features, or change substantively in response to tiny variations in training procedure (e.g., changing the random seed). The aim of this project is to develop methods to mitigate this kind of failure by baking in causal knowledge to model design and evaluation. For example, we may know changing certain input features shouldn’t change predictions (e.g., your medical diagnosis shouldn’t change if we edit your zipcode), or we may know something about common causal structure between domains (rain should affect a self-driving car the same in Chicago and New York). The challenge here is to translate domain knowledge and desiderata into formal requirements, and then determine how to enforce and measure these using available data.

Bio: I am an assistant professor of Statistics and Data Science at the University of Chicago and a research scientist at Google Cambridge. My recent work revolves around the intersection of machine learning and causal inference, as well as the design and evaluation of safe and credible AI systems.

Project: Designing next generation batteries with AI

Description: A sustainable energy economy requires an immediate shift to renewable
technologies, and batteries are vital to counterbalance the intermittency of solar and wind.
Batteries consist of an anode, cathode, and an electrolyte; while the anode/cathode selection
determines the theoretical energy density, the electrolyte choice often controls battery lifetime.
Furthermore, electrolyte selection can determine how fast a battery charges, battery operation
temperature, and safety. The conflicting requirements for electrolytes often mean that
electrolytes are discovered using trial-and-error approaches; slowing down research progress and
time to commercialization. Here, data science and the ability of AI to extract meaning from
complex data is of vital interest. We have a multitude of data science + battery projects. One
example project involves the development of natural language processing (NLP) and computer
vision algorithms to extract battery data from the literature to build machine learning models.
Although the scientific literature contains decades of relevant battery information, utilization of
this data has been stifled by the lack of NLP tools capable of digesting the information. The
second example project is focused on developing ML tools and applying these tools to discover
novel electrolyte compounds for novel battery chemistries. Combining your data science
expertise with the battery (and materials) domain knowledge that you will obtain from our
laboratory will provide you with a skillset to exploit the battery sector that is expected to grow to
over 100 billion dollars by 2025.

Projects: Data-driven Environmental Enforcement

The Energy and Environment Lab invites a postdoc to collaborate on a suite of projects that leverage advances in monitoring technology and machine learning approaches to inform environmental policy, under the mentorship of Michael Greenstone, the Milton Friedman Distinguished Service Professor in Economics, the College, and the Harris School; Director of the Energy and Environment Lab, the Becker Friedman Institute, and the Energy Policy Institute at Chicago.

Congestion and Traffic Safety

Many cities across the United States have adopted Vision Zero, the policy goal of eliminating all traffic-related deaths and serious injuries. But what are the costs of achieving Vision Zero and what are the most efficient policy instruments to get there? Monitoring technologies offer the potential to revolutionize urban policy by providing governments with big data to inform policymaking. As part of NYC’s Vision Zero, the Department of Transportation is more than quintupling the number of speed cameras in the city. Leveraging our access to unique data of taxi, for-hire vehicle, and city fleet trips to model the impacts of new traffic cameras on vehicle crashes, slowdowns, and congestion spillovers. The post-doc would utilize large administrative datasets on camera enforcement, vehicle crashes, segment-level traffic speeds, and high-resolution driver behavior, to help measure the costs and benefits of enforcement strategies for fatality/injury reduction to inform optimal policy for urban traffic safety.

Leveraging Satellite Data to Reduce Oil & Gas Methane Emissions

The meteoritic rise of shale oil and gas (O&G) drilling in the United States poses significant challenges for reducing greenhouse gas emissions. The methane emitted has around 30 times greater short-term global warming potential than CO2, contributing aggressively to climate change. Reliable estimates of emitted methane are essential to fully understand and mitigate the environmental threat presented by shale drilling. While some estimates suggest that approximately 2.3% of gross natural gas production is leaked per year, accurate monitoring of emissions remains extremely challenging. Currently, regulators visit individual facilities to measure emissions; but due to budgetary constraints and a fast-growing industry inspector can visit only a fraction of the facilities each year. This project will leverage a wealth of administrative data and novel remote sensing data from recently-launched satellites to estimate facility-level methane emissions. Leveraging these unique data and state-of-the-art machine learning techniques, the project will help regulators re-design their monitoring and enforcement strategy to realize improvements in regulatory efficiency and reductions in greenhouse gases.

Beyond Inspection Targeting: Deterrence through Machine Learning

Building on a three-year partnership with the Environmental Protection Agency (EPA), this project aims to scale a machine learning-driven framework across inspection targeting programs at EPA. The Clean Water Act (CWA) is one program where data-driven inspection targeting can directly influence environmental policy. Using state-of-the-art machine learning models, we can generate risk scores for the likelihood individual firms will violate CWA standards, and use these model-generated risk scores to study facility compliance behavior and identify the most effective approaches to deterrence in a randomized field trial.

Language learning has come to be a central theme in both cognitive science and artificial intelligence. The nature of language learning has long been a topic of interest for cognitive scientists, and machine learning has begun to dominate natural language processing (NLP) in modern AI. NLP systems have benefited tremendously from machine learning. However, the learning systems developed using these procedures often don’t achieve the efficiency and robustness of human language acquisition. Insights from language acquisition have the potential to help address this problem. But there are two critical challenges in exploring this possibility: (1) identifying the innate learning biases that enable fast, robust language learning in humans, and (2) determining how to translate theoretical insights about these biases into effective implementation for learning in NLP systems. This project will tackle both of these issues, making use of insights from special linguistic populations.

Our first challenge –– identifying innate language learning predispositions –– is driven by the fact that most children are exposed to linguistic input from birth, making it difficult to disentangle innate characteristics versus characteristics that are rapidly learned from input. The rare cases in which children do not have usable linguistic input can help here by allowing us make important headway in identifying these predispositions. Congenitally deaf children who cannot learn the spoken language that surrounds them, and who have not been exposed to sign language by their hearing families, are in the unique situation of being without language input early in life. These children use their hands to communicate –– they gesture –– and those gestures (called “homesigns”) take on many, but not all, of the forms and functions of languages that have been handed down from generation to generation. The properties of these naturally-arising gestures provide evidence for the nature of linguistic predispositions independent of input.

Drawing candidate biases from homesign, we will then tackle the second challenge –– incorporating biases into machine learning systems –– by systematic testing of models against real-world child language acquisition data. The goal of this phase will be to identify effective means of instantiating proposed human biases, and to test whether models incorporating these biases will successfully simulate the learning trajectories exhibited by children. Models with the proposed biases will be compared against minimally-different baseline models lacking the biases; stronger fit to human data will be taken as support that the biases are actual human predispositions. An important priority of this phase will be to balance scientific and engineering needs –– to maintain transparency of the models’ cognitive implications and to simulate human learning patterns as closely as possible, but also to use models that will interface smoothly with modern NLP systems, with promise to scale to larger datasets and broader domains.

Dr. Allyson Ettinger’s research is focused on language processing in humans and in artificial intelligence systems, motivated by a combination of scientific and engineering goals. For studying humans, her research uses computational methods to model and test hypotheses about mechanisms underlying the brain’s processing of language in real time. In the engineering domain, her research uses insights and methods from cognitive science, linguistics, and neuroscience in order to analyze, evaluate, and improve natural language understanding capacities in artificial intelligence systems. In both of these threads of research, the primary focus is on the processing and representation of linguistic meaning.

Project: Operational Analytics for Communications Systems

Many applications of machine learning to computer communications systems such as the Internet rely on models that are trained offline, on snapshots of data. Yet, in many operational systems, data arrives as a continuous stream—often as a timeseries, and decisions must be made on short timescales (e.g., milliseconds). In operational systems, designers must face difficult challenges and design tradeoffs concerning encoding of timeseries data, efficiently labeling large quantities of data, distinguishing anomalous activity from model drift, and trading off model accuracy versus model or feature complexity. In this research project, we will explore these challenges in the context of networked systems. Possible avenues include device identification and anomaly detection in industrial control systems and consumer “IoT” smart homes; streaming video quality estimation; content moderation on social media platforms (e.g., Facebook); and security vulnerability detection in networked systems.

Mentor: Susan Goldin-Meadow, Beardsley Ruml Distinguished Service Professor in the Department of Psychology and Committee on Human Development

Susan Goldin-Meadow is the Beardsley Ruml Distinguished Service Professor in the Department of Psychology and Committee on Human Development at the University of Chicago. A year spent at the Piagetian Institute in Geneva while an undergraduate at Smith College piqued her interest in the relationship between language and thought, interests she continued to pursue in her doctoral work at the University of Pennsylvania (Ph.D. 1975). At Penn and in collaboration with Lila Gleitman and Heidi Feldman, she began her studies exploring whether children who lack a (usable) model for language can nevertheless create a language with their hands. She has found that deaf children whose profound hearing losses prevent them from learning the speech than surrounds them, and whose hearing parents have not exposed them to sign, invent gesture systems which are structured in language-like ways. This interest in how the manual modality can serve the needs of communication and thinking led to her current work on the gestures that accompany speech in hearing individuals. She has found that gesture can convey substantive information – information that is often not expressed in the speech it accompanies. Gesture can thus reveal secrets of the mind to those who pay attention.

Professor Goldin-Meadow’s research has been funded by the National Science Foundation, the Spencer Foundation, the March of Dimes, the National Institute of Child Health and Human Development, and the National Institute of Neurological and Communicative Disorders and Stroke. She has served as a member of the language review panel for NIH, has been a Member-at-Large to the Section on Linguistics and Language Science in AAAS, and was part of the Committee on Integrating the Science of Early Childhood Development sponsored by the National Research Council and the Institute of Medicine and leading to the book Neurons to Neighborhoods. She is a Fellow of AAAS, APS, and APA (Divisions 3 and 7). In 2001, she was awarded a Guggenheim Fellowship and a James McKeen Cattell Fellowship which led to her two recently published books, Resilience of Language and Hearing Gesture. In addition, she edited Language in Mind: Advances in the Study of Language and Thought in collaboration with Dedre Gentner. She has received the Burlington Northern Faculty Achievement Award for Graduate Teaching and the Llewellyn John and Harriet Manchester Quantrell Award for Excellence in Undergraduate Teaching at the University of Chicago. She is currently the President of the Cognitive Development Society and the editor of the new journal sponsored by the Society for Language Development, Language Learning and Development. Professor Goldin-Meadow also serves as chair of the developmental area program.

Project: Machine Learning for Physical Systems
Much of machine learning is focused on recognizing patterns and making predictions based on training data. However, in many physical science settings, the complexity of the task is too high for effective learning giving the amount of available data. In these settings, it is essential to incorporate knowledge of the underlying physical system to mitigate the effect of limited data. Examples include using a combination of training data and models of a CT scanners operation to develop better medical image reconstruction methods, leveraging both observational and simulated data to develop better climate predictions, and building deep learning-based surrogate models for computationally demanding PDE-based simulators of physical systems. While there are isolated examples of successes in these regimes, little is known on a fundamental level. What are optimal machine learning methods that leverage both training data and physical models? How does sample complexity scale with the type of physical system and the accuracy of our models? Which kinds of PDE models are most amenable to deep surrogate models? This project will focus on developing new methodology and theory for machine learning for physical system that will address these and other open problems.

Project: Nightingale Project

Machine learning, we are told, will transform medical diagnosis and patient care: by integrating ‘big data’ on patients’ history and physiology, algorithms can dramatically improve the quality of doctors’ decisions, with the potential both to reduce waste, avoid misdiagnosis, and produce breakthrough discoveries. For example, if massive datasets of ECG waveforms could be linked to national mortality registries, we could supercharge the current research, and find better, more consistent ways to allocate life-saving defibrillators. But most clinical data like this is siloed by different institutions and unavailable to researchers. Further complicating things, in order to protect patient privacy, public medical datasets are almost universally limited to a single, easily de-identified stream of information, like a set of X-rays.

The goal of the Nightingale Project in the Booth Center for Applied AI is to gather and share just the sort of rich, multidimensional data needed to feed AI-enabled discovery. Work with a team of engineers, data analysts, and medical experts to build a secure platform that can warehouse curated de-identified clinical datasets linked to ground truth outcomes. Using this initiative as a proof of concept to develop other privacy tools, own and work through the de-identification, sharing, and privacy components of large-scale datasets — work that will include writing models and creating security-related challenges — with the goal of making the data available to researchers securely.

Project: Machine Learning to Improve Targeted Cancer Therapy

Advances in genomics have created many new cancer therapies that target specific genetic or molecular features, raising the potential for personalized treatment that improves effectiveness and decreases side effects. However, the majority of patients treated with targeted therapies do not respond as predicted, and detailed patient genomic information is expensive to acquire.

This collaboration proposes to improve targeting of cancer therapies by developing new AI approaches that recommend the best treatment based on a combination of genetic and pathology data. Researchers will build new methods drawing upon computer vision and machine learning to gather essential contextual information about individual cancers from tumor samples, utilizing both genomic and image-based features. This work will advance both artificial intelligence and cancer-focused data science by developing innovative solutions to emerging machine learning problems in cancer research, ultimately benefiting patients through more targeted, effective treatments.

Project: Early Childhood Metric Initiative

Early childhood suffers from a lack of quantifiable data that is easy to collect at scale. Work with a team of engineers, computer scientists, and early childhood experts to build a non-intrusive, wearable technology that leverages machine-learning to collect real-time, real-world data to measure young children’s early language environments (i.e. the quantity and quality of language interactions they are exposed to). As part of the project, develop machine learning algorithms and models to analyze the large-scale adult-child interaction data collected from this wearable technology. This large dataset will enable researchers and practitioners to better understand the relationships between family demographics, parental inputs, and child outcomes and identify effective approaches, as well as enable policymakers to hone in on the most effectives programs and policies to enhance children’s early language environments. This audio dataset will also allow experts in natural language processing to develop and refine speech processing algorithms.

Project: Pediatric Cancer Data Commons

Collecting, aggregating, harmonizing, and sharing data from children with cancer is essential to making new discoveries and developing new cures. Too often, data are siloed and disconnected, drastically reducing the usefulness of these valuable resources. The Pediatric Cancer Data Commons (PCDC) at UChicago brings together researchers from around the world with the goal of building data dictionaries for all types of pediatric cancer. Consensus data models are balloted with experts from around the world, including clinicians, ontologists/taxonomists, statisticians, and data scientists. The resulting dictionary is used for harmonizing data from completed clinical trials and is subsequently leveraged as a framework for collecting data on new studies. The data are made available to the worldwide research community through a public-facing cohort discovery tool. Data are further connected to other sources through common identifiers, allowing novel new data sets to be developed for research and discovery.

Project: Corporate influence on the rulemaking process within the United States

The rulemaking process in the United States includes an opportunity for public comment in between a new regulation and implementation of a rule change. During this comment period, not only the public at large, but corporations as well are able to exert influence over rule changes. Using textual analysis techniques, we aim to understand how this process of influence works – to what extent corporate influence affects rule changes and what kinds of changes ultimately result.

Project: Combining human and machine intelligence for policy impact

The success of artificial intelligence (AI) for engineering and commercial applications has led to growing interest in using these tools to help solve important social problems like inequality in income, education, health, or criminal justice system involvement. But any realistic assessment of how AI will be used in these areas suggests it will be a complement to, not substitute for, human judgment. That is, AI will be used as decision aids, not decision makers. In previous work (Kleinberg, Lakkaraju, Leskovec, Ludwig and Mullainathan, 2018 Quarterly Journal of Economics) we have found in the context of criminal justice system decision-making that humans on net add negative value to the machine’s predictions of defendant risk, although in principle the private information humans can access that algorithms cannot (such as courtroom discussion about the details of the case) could help the human add positive value in at least some cases. Similar issues arise in numerous other policy domains such as medical diagnosis, hiring, credit, and education admissions. The goal of this project is to better understand the potential sources of human and machine comparative advantage by measuring the private information humans have access to in different decision-making domains, trying to understand what are useful sources of signal versus sources of noise for human decisions about when to follow versus over-ride the algorithm’s recommendations, and then try to build decision-making systems that lead to the human plus machine together to outperform the decisions implied by the machine’s predictions alone.

Jens Ludwig is the Edwin A. and Betty L. Bergman Distinguished Service Professor, director of the University of Chicago’s Crime Lab, codirector of the Education Lab, and codirector of the National Bureau of Economic Research’s working group on the economics of crime.

In the area of urban poverty, Ludwig has participated since 1995 on the evaluation of a HUD-funded randomized residential-mobility experiment known as Moving to Opportunity (MTO), which provides low-income public housing families the opportunity to relocate to private-market housing in less disadvantaged neighborhoods. In the area of education he has written extensively about early childhood interventions, and about the role of social conditions in affecting children’s schooling outcomes. In the area of crime, Ludwig has written extensively about gun-violence prevention. Through the Crime Lab he is also involved in partnering with policymakers in Chicago, New York City, and across the country to use tools from social science, behavioral science, and computer science to identify effective (and cost-effective) ways to help prevent crime and violence. This includes studies of various social programs, helping the Chicago Police Department use data to reduce gun violence and strengthen police-community relations, and work underway to use data science to help New York City build and implement a new pretrial risk tool as part of the city’s goal to close Riker’s Island. Crime Lab projects have helped redirect millions of dollars of public-sector resources to evidence-based strategies and have been featured in national news outlets such as the New York Times, Washington Post, Wall Street Journal, PBS News Hour and National Public Radio. In 2014 the Crime Lab was the recipient of a $1 million MacArthur Award for Creative and Effective Institutions, the organizational equivalent of the foundation’s “genius prize.”

His research has been published in leading scientific journals across a range of disciplines including Science, New England Journal of Medicine, Journal of the American Medical Association, American Economic Review, Quarterly Journal of Economics, the Economic Journal, and the American Journal of Sociology. His coauthored article on race, peer norms, and education with Philip Cook was awarded the Vernon Prize for the best article in the Journal of Policy Analysis and Management.

I am an Assistant Professor of Computer Science at the University of Chicago. I founded and direct 3DL (threedle! ), a group of enthusiastic researchers passionate about 3D, machine learning, and visual computing. I obtained my Ph.D. in 2021 from Tel Aviv University under the supervision of Daniel Cohen-Or and Raja Giryes.

My research is focused on building artificial intelligence for 3D data, spanning the fields of computer graphics, machine learning, and computer vision. Deep learning, the most popular form of artificial intelligence, has unlocked remarkable success on structured data (such as text, images, and video), and I am interested in harnessing the potential of these techniques to enable effective operation on unstructured 3D geometric data.

We have developed a convolutional neural network designed specifically for meshes, and also explored how to learn from the internal data within a single shape (for surface reconstruction, geometric texture synthesis, and point cloud consolidation) – and I am interested in broader applications related to these areas. Additional research directions that I am aiming to explore include: intertwining human and machine-based creativity to advance our capabilities in 3D shape modeling and animation; learning with less supervision, for example to extract patterns and relationships from large shape collections; and making 3D neural networks more “interpretable/explainable”.

Sanjay Krishnan is an Assistant Professor of Computer Science. His research group studies the theory and practice of building decision systems that are robust to corrupted, missing, or otherwise uncertain data.
