bullet item Graduate Students

bullet item David Barbella
David joined QRG in Fall 2008. His research interests include using analogy to tackle challenges in natural language understanding, especially in the context of learning by reading. He is involved in the Companions project.

bullet item Joe Blass
Joe Blass wants to build systems that think, act, and interact like humans.  Currently his research focuses on modeling commonsense reasoning and social cognition, particularly moral reasoning.  Joe joined QRG in Fall 2013.

bullet item Maria Chang
Maria's research interests include AI applications in education, spatial learning and diagrammatic reasoning. She is a member of the CogSketch team, where she works on improving coaching and tutoring within CogSketch and exploring new sketch-based intelligent tutoring systems. Maria joined QRG in Fall 2009.

bullet item Max Crouse.
Max joined QRG in Fall 2015. His research interests are in building reasoning systems to acquire and handle human levels of knowledge.

bullet item Balasubramanian ("Subu") Kandaswamy
Subu joined QRG in fall 2010. He is interested in doing research at the intersection of artificial intelligence and psychology. He is currently investigating cognitive models of how children learn relational abstractions.

bullet item Chen Liang
Chen wants to build human-level AI , upload his mind, and then live forever. His research interests include cognitive modeling, machine learning, knowledge representation and cognitive architecture. Past research includes building models of human conceptual learning and using structure mapping for statistical relational learning with semantic web data. He joined QRG in fall 2013. 

bullet item Clifton McFate
Clifton McFate joined QRG in Fall 2012. His research interests include natural language processing, frame semantics, and knowledge representation. He is currently working on an NLP system that uses narrative expectations to abductively interpret explanatory natural language texts and that builds qualitative models based on these interpretations. Past research includes using VerbNet to automatically create semantic frames as well as the NULEX Lexicon.

bullet item Matt McLure
Matt McLure wants to investigate what it would take for a cognitive architecture to participate in robust concept learning through long-term, multi-modal interaction. To this end, he is particularly interested in active learning techniques, flexible representation schemes, re-representation strategies, and sketch understanding. He has been with QRG since the fall of 2009, and is involved in the Freeciv, Companions, and CogSketch projects.

bullet item Irina Rabkina
Irina joined QRG in fall 2015. She is interested in using artificial intelligence techniques to improve our understanding of human cognition, and our understanding of human cognition to improve artificial intelligence techniques. She is currently working on modeling Theory of Mind.
