Benjamin Marlin
Assistant Professor

Professor Marlin's research interests lie at the intersection of artificial intelligence, machine learning and statistics. Professor Marlin's current research explores the development of novel machine learning models and algorithms in a number of application areas including health and behavioural science. He is particularly interested in hierarchical, probabilistic graphical models and approximate inference and learning techniques including Markov Chain Monte Carlo and variational Bayesian methods.

Brendan O'Connor
Assistant Professor

Prof. O'Connor develops natural language processing and machine learning methods to analyze social questions in text corpora, such as news or social media. For example: analyzing Twitter to understand how new slang spreads between cities, and how textual sentiment corresponds to public opinion polls. Other applications have looked at censorship in Chinese microblogs and extracting events in international relations from the news.

Daniel Sheldon
Assistant Professor

The primary goal of Professor Sheldon’s research is to develop algorithms to understand and make decisions about the environment using large data sets. He seeks to answer foundational questions (what are the general models and principles that underlie big data problems in ecology?) and also to build applications that transform large-scale data resources into scientific knowledge and policy.

Hanna Wallach
Adjunct Associate Professor

Hanna Wallach is a Senior Researcher at Microsoft Research New York City and an Adjunct Associate Professor in the College of Information and Computer Sciences at the University of Massachusetts Amherst. She is also a member of UMass’s Computational Social Science Institute. Hanna develops machine learning methods for analyzing the structure, content, and dynamics of social processes.

Juston Moore
Alumni (LANL)

Juston is a Masters student in the UMass Department of School Science working with Professor Hanna Wallach. He is interested in quantifying and predicting the spatial and temporal dynamics of information exchange in networks, with applications including anomaly and changepoint detection. Juston's prior work was in cyber security, with an emphasis on vulnerability detection and mitigation in corporate networks. He received his BS degree from the New Mexico Institute of Mining and Technology in 2010.

Annamalai Natarajan
PhD Candidate

I am a PhD candidate at the School of Computer Science. I am broadly interested in probabilistic models, inference in these frameworks and their applications. Prior to coming to UMass, I worked as a research assistant for Ken Norman at the Princeton Computational Memory lab. At Princeton we studied the effects of memory retrieval in humans. Even before that I got my Masters from Colorado State University working with Chuck Anderson on Brain Computer Interface applications.
