welcome.
I'm a Computer Science Ph. D. candidate at Northwestern University. I received my B.S. in Computer Science and M.S. in Computer Science from Washington University in St. Louis, in 2003 and 2005, respectively.
Since 2007, I've researched with the Qualitative Reasoning Group within the field of Artificial Intelligence.
(Update: Northwestern University has posted a highlight on my research.)
Learning Causal ModelsMany existing theories of inferring causality incorporate statistics alone; In addition to statistics, I am using qualitative models to represent the actual mechanisms of change and permit deeper domain theories. Conceptual ChangeWhen people encounter new information via observation or instruction, it may conflict with our present beliefs. In these cases, we have the ability to change our beliefs - and even the categories we use to represent them. This is the process of conceptual change. I am devising a computational model of this process to (1) provide insight into human cognition and (2) improve the robustness of system that reason over extended operation within knowledge-rich domains. |
