Susan Brennan is Professor of Cognitive Science in the Department of Psychology at Stony Brook University, with affiliations in Computer Science and Linguistics. Her research for the past 35 years has focused on psycholinguistics, verbal and nonverbal communication, audience design in writing and speaking, and the human use of technology. Earlier in her career, she conducted research at Atari, Apple, and Hewlett Packard Labs on topics including computer-generated caricature, mediated communication, and natural language and speech interfaces to computers. Current interests include human-AI interaction, the impacts of AI and bias on stakeholders, and whether/how an automated agent could learn to be a capable dialogue partner. See this presentation, at AAAS '21 (Annual Meeting of the American Association for the Advancement of Science), "Conversational Challenges of AI Teaming with Humans," (starts 1:15 in) and this keynote address from CUI '19 (Conversational User Interfaces, Dublin, Ireland), "Can Machines Learn to Converse? What We Know from >30 Years of 'Conversational Interfaces'." From 2015-2018 she served as Program Director at the National Science Foundation for the Graduate Research Fellowship Program.
Professor Ramakrishnan’s current research interests are knowledge representation and quantum computation. In knowledge representation, he works on systems that combine statistical and logical knowledge: ways to represent such knowledge, perform inference and learning over such knowledge, and design probes to maximize their information content. An application of such a combined statistical/logical system is the verification of probabilistic concurrent systems. In quantum computation his recent work is broadly in building and using quantum networks: techniques for efficiently sharing quantum information across a network, and for distributing computation over a network of quantum computers. He currently serves as the Graduate Program Director of Computer Science.
Professor Wei Zhu is a statistician and data scientist whose diverse research projects include the development and application of novel methods for (1) longitudinal and contemporaneous pathway discovery and analysis (for biological pathways, climate models and financial networks); (2) detection and classification of financial bubbles and crashes; (3) errors in variable regression (for situations when both the dependent and the independent variables suffer from random errors, which are indeed prevalent in real life and research); and (4) machine learning methods (for practical scenarios such as when the training sets are unbalanced). It is well known that each real world problem and dataset can often be modeled and analyzed in different ways – the key is to find the best way to obtain as valid and unbiased inference as possible. In parallel to this pursuit of methodology development, we also aim to help answer important questions to science and society. The following link features one of our latest research papers where we studied climate warming, sea level rising and their impact from a data science perspective: https://doi.org/10.3390/stats5010002. Another recent research paper can be found here. In this paper we use a reinforcement-learning framework, a frontier topic in data science and machine learning, to tackle the problem of vehicle mobility optimization.
Jeffrey Heinz is a Professor of Linguistics at Stony Brook University, with a joint appointment in its Department of Linguistics and Institute of Advanced Computational Science. While he has conducted research in several related areas including computational and mathematical linguistics, computational learning theory, grammatical inference, theoretical computer science, and artificial intelligence, a primary focus is how humans come to know linguistic generalizations on the basis of their linguistic experience. In particular, he aims to identify biases that humans unconsciously bring to bear on language-learning. The kinds of biases he studies often regard the question "What does it mean for a pattern to be simple?" and he studies this question with respect to sequences and other recursive data structures. He has helped identify several subregular classes of formal languages which (1) instantiate different kinds of simplicity biases, (2) have logical and algebraic interpretations, (3) facilitate learning from examples, and (4) help explain why linguistic patterns are what they are. A recent article exemplifying this research can be found here: https://doi.org/10.15398/jlm.v9i1.262
Dr. London’s research aims to identify and explore the psychosocial and institutional mechanisms associated with social identity threat, and the consequences of threat for academic achievement and psychosocial well-being of historically marginalized groups (on the basis of gender, race, ideology and sexual orientation). Utilizing longitudinal, social-cognitive experimental, and survey methodology, Dr. London’s research lab takes a multi-method approach to studying social identity processes. Dr. London has developed and tested psychosocial models of threat and engagement among women and ethnic minority group members in Science, Technology, Engineering and Math (STEM), business, leadership and law fields.

Braden Brinkman earned his B.Sc. in Physics at Simon Fraser University in British Columbia, Canada, and went on to do his Ph.D. studies in non-equilibrium statistical physics at the University of Illinois at Urbana-Champaign. Brinkman's main research interests concern statistical models of behavior and coding in neural populations: what collective behaviors can interacting networks of neurons exhibit, what interactions give rise to those behaviors, how do networks encode and perform computations on their inputs, and how do network structure and external environments or stimuli modify these behaviors and computations? Experimental and theoretical work has demonstrated that the properties of neural circuitry are shaped during development by these sensory experiences, and different types of stimuli can result in different perceptions or behavior. Understanding how environments influence development is a key question in neuroscience. In addition to this research direction, Brinkman is also interested in improving the accessibility of STEM materials, which are often conveyed in highly visual formats or through media that present a barrier to learning for some students.

Christian Luhmann is an Associate Professor of Cognitive Science at Stony Brook University. Luhmann's lab focuses on complex behavior with a particular focus on decision making and learning and the interplay between these behaviors. His lab members explore these interests in a variety of domains. They also use a variety of methodological tools, including behavior and computational modeling as well as neuroscientific methods such as EEG and fMRI. Luhmann is interested in how people make decisions in the face of incomplete, inconsistent, ambiguous, or uncertain information. Using behavioral and computational methods, his work in the area of learning suggests that learners are adept at dealing with incomplete data, a situation ignored by current learning theories. Luhmann uses functional magnetic resonance imaging in his work on economic decision-making, where he explores the neural bases of decision-makers' ability to foresee, evaluate, and react to the presence of uncertainty. His behavioral work on perceptual decision-making explores both how even relatively simple decisions involve integrating noisy information over time and how decision-makers evaluate quantities such as confidence.
