Vasanth Sarathy

Vasanth Sarathy, Ph.D.

Research Assistant Professor

Vasanth Sarathy received a Ph.D. in Computer Science and Cognitive Science from Tufts University, an M.S. in EECS from M.I.T., and a J.D. from Boston University School of Law. Before Tufts, he was a Senior Researcher at Smart Information Flow Technologies (SIFT) where he worked closely with the Department of Defense and the Intelligence Community to solve cutting-edge AI challenges. His current research combines neural and symbolic approaches to make generative AI systems more creative and inventive while staying within the bounds of human socio-cultural norms. He also loves to draw single-panel cartoons. Visit vsarathy.com to learn more about his current projects.

Evan Krause

Evan Krause, MS

Senior Robotics Researcher, Lab Manager

Evan Krause received a MS degree in Applied Mathematics from the University of Washington. He is a senior staff member in the HRI Lab and his current research interests include failure detection and recovery, problem solving, and architecture development for robots in open worlds.

Thomas Arnold

Thomas Arnold, ABD

Research Associate

Thomas Arnold is a research associate at HRILab, whose work focuses on moral and social norms in human-robot interaction. His articles have addressed standards of explanation, verification, and supererogation in robotic decision-making, as well as the limits of moral dilemmas for their evaluation. He is currently researching the normative demands of care contexts on explicit reasoning and instructions for robots. He often represents HRILab in its partner role in the PartnershipAI (PAI), and in 2019 he served as co-organizer of “Coding Caring,” one of two studies commissioned by the One Hundred Year Study on Artificial Intelligence (AI100). He assists in programming discussions of AI’s impact on culture and religion for the group AI and Faith, and he is completing a doctoral dissertation in Harvard’s Committee on the Study of Religion on appeals to experience in the philosophy of religion. He is the co-author of “Ethics for Psychologists: A Casebook Approach” (Sage 2011).

Marlow Fawn

Marlow Fawn

Research Engineer

Marlow Fawn received their B.S. in Mechanical Engineering at Tufts in 2019, with a minor in computer science. They have been affiliated with the HRI lab since then, and hope to continue their studies in the fields of AI, cognitive architecture, and embodied systems.

Matthew McWilliams

Matthew McWilliams

Senior Programmer

Matt has worked as a software developer for over a decade for retail, non-profit and higher education clients as well as deploying AI-powered applications for public-sector and government customers. His work focuses on creating immersive VR simulation environments for learning and research. He received a BFA from Emerson College in 2009.

Christopher Thierauf

Christopher Thierauf, MS

Ph.D. Student

Chris Thierauf is currently pursuing a joint PhD in Computer Science and Human-Robot Interaction after completing a bachelors in computer science in 2020. His research work focuses on resiliency in open worlds: by designing systems that use knowledge and reasoning to understand failure and invent solutions, robots can better handle the chaos of human environments.

Sarah Schneider

Sarah Schneider, MS

Ph.D. Student

Sarah Schneider received a Bachelor and Master degree in Biomedical Engineering from the Technical University Graz and she is currently doing her PhD in Computer Science at Tufts University. Her research focuses on novelty detection and description in computer vision tasks by incorporating semantic information.

Mitchell Abrams

Mitchell Abrams, MS

Ph.D. Student

Mitchell Abrams received his BA from Binghamton University in Linguistics and an MS in computational linguistics from Georgetown University. His former work in linguistics and natural language processing has touched on a broad range of topics, which include leveraging abstract meaning representation (AMR) for human-robot communication, creating annotated corpus resources for the Coptic language, and analyzing corpora within the forensic context. Mitchell has developed his skills at the US Army Research Laboratory and the Aston Institute of Forensic Linguistics (UK), where he was a visiting researcher. His current research in the human-robot interaction laboratory focuses on natural language understanding, reference resolution, and social norms.

Ayca Aygun
