Research interests

My current research focuses on how cognitive processes such as attention and memory operate on distributed neural representations. Particularly, I’m interested in how attentional allocation, as a filtering mechanism, can transiently warp neural representational space. My broader interests include neuromorphic computational models, network analyses, and information theoretic accounts of sensory processing.
