Bruno Richard

Bruno Richard

I am a postdoctoral associate in the department of Mathematics and Computer Science at Rutgers University - Newark. I earned a B.A. psychology from Concordia University in Montreal and continued on to complete my Ph.D. investigating human sensitivity to natural scene statistics with Aaron Johnson and Bruce Hansen. I then spent 18 months in the UK as a postdoc in the Department of Psychology at the University of York working on a project investigating the neural mechanisms of binocular vision.

My research focuses on the study of early visual mechanisms. Specifically, I am interested in defining the association between the characteristics of early visual properties to the statistical properties of the natural environment. I rely a combination of psychophysical, neuroimaging, neurostimulation, and computational modelling methods in my research. In the CoDaS lab, I am part of the virtual reality project, which aims to modify human perception by altering the statistical properties of the environment.

Libby Barak

Libby Barak

I am a postdoctoral associate in the department of Mathematics and Computer Science at Rutgers University - Newark. I completed my M.Sc. at Bar-Ilan University working on text classification and earned my Ph.D. from the University of Toronto while working on models of verb acquisition. I then spent two years as a post-doc in the Psychology department at Princeton University working with Adele Goldberg exploring models of language learning.

My research interests are in the areas of cognitive modeling of language and learning. My goal is to create computational models that simulate plausible representations of the learner and the input by accounting for theoretical findings from experimental observations on human behavior. By using this modeling approach, I aim to clarify how learning and linguistic factors interact to facilitate the rapid pace of natural language learning and how learning may vary given individual differences among learners.

Wai Keen Vong

Wai Keen Vong

I am currently a Post-Doctoral Associate in the Department of Mathematics and Computer Science at the University of Rutgers - Newark. Previously, I completed my PhD in Psychology at the University of Adelaide with Amy Perfors, Daniel Navarro and Drew Hendrickson, where my research explored how both structure and label information shape how people learn categories.

My current research interests are in areas such as pedagogy, cooperation and explanation, particularly as they relate to knowledge of concepts. From a cognitive science perspective I’m interested in the kinds of conceptual representations that allow people to learn and teach the kinds of concepts in the natural world. I’m also interested in how teaching can help learning different kinds of knowledge, figuring out when and how teaching is effective and the implications of this for pedagogy and education. Finally, I’m interested the technical aspects of many of these problems, such as scaling inference algorithms to work on more interesting problems in teaching and the use of probabilistic programming languages for cognitive modeling.

I completed my MS in Computer Science at NYU’s Courant Institute, where I focused on machine learning and data science. I transitioned from a research background in cellular neuroscience (neuropathic-pain signaling) to cognitive computational modeling. My methodological interests encompass machine-learning based joint-modeling approaches to explain the dynamics of brain and behavior. In particular, I am interested in how knowledge is acquired, represented in the brain, and subsequently used to guide behavior.

Paxton Edgar

Paxton Edgar

I am a senior undergraduate at Rutgers pursuing a B.S. in Biology while minoring in Computer Science. I began my research career with Dr. Radek Dobrowolski and Dr. Edward Bonder investigating molecular mechanisms leading to neuronal death observed in Alzheimer’s and Parkinson’s disease via the PI3K/AKT/mTOR pathway. My research interests are in the developing and refining models through machine learning and statistical analysis to make use of data, such as -omic data and its use in identifying drug targets within molecular pathways. Such models must be scrutable, however, in order for life science professionals to make impactful use of them. In the spirit of such, currently, I am interested in the applications of Bayesian inference in its use towards explaining machine learning models.

As a post-baccalaureate research assistant in the CoDaS Lab, I currently (1) develop teaching models for the Explainable Artificial Intelligence project and (2) model neural response manifolds for the augmented reality project.

I earned my B.A. in Biology and Philosophy at Rutgers University—Newark in 2014; my Honors thesis was on age differences in probabilistic category learning from reinforcement, advised by Dr. Mark Gluck at the Center for Molecular and Behavioral Neuroscience. After graduating, I continued my work with Dr. Gluck for two years, investigating the effects of aging, genetics, and exercise on striatal and hippocampal dependent learning.

My first position out of the lab was as Data Scientist at Monsanto. I was postdoctoral associate in the Department of Mathematics and Computer Science at the University of Rutgers - Newark. Before that I was a research engineer with the MIT Probabilistic computing project. And Before that I was an experimental psychology graduate student at the University of Louisville.

Broadly speaking, my research focuses on learning. On the psychological side, I seek to reverse-engineer human social learning by defining it in the language of mathematics—the ultimate goal being to endow computers with the ability to communicate concepts to humans in a natural, pedagogical, human way. On the data science side, I develop tools that improve subject-area experts’ ability to answer the questions important to them without them having to mangle their data to fit into off-the-shelf software and without them having to spend time becoming machine learning and programming experts.
