welcome.
I completed my Ph.D at Northwestern University in June 2012. 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.
From 2007-2012, I researched with Northwestern's Qualitative Reasoning Group within the field of Artificial Intelligence. The graduate school posted a highlight on my research here.

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 existing beliefs. In these cases, we have the ability to revise our beliefs about the world and the models and categories we use to represent the world. This is the process of conceptual change. My dissertation describes a computational model of this process, which provides insight into human cognition and aims to eventually improve the robustness of systems that reason over extended operation in knowledge-rich domains. |
