Asohan Amarasingham

Profile

As an undergraduate at Virginia (B.Sc., Mathematics &Cognitive Science, 1997), influenced by Chip Levy, I developed an interest in the mathematical and statistical foundations of emerging branches of the neural and cognitive sciences. I completed graduate study at Brown (M.Sc., Cognitive &Linguistic Sciences, 1999;Ph.D., Applied Mathematics, 2004), where I worked in the group and wrote a dissertation under the supervision of , on statistical topics in neurophysiology. Following a period of teaching mathematics at the University of Jaffna, Sri Lanka, I completed my postdoctoral training in the laboratory of neurophysiologist at Rutgers. I joined the faculty at City College and the Graduate Center in 2010-11

Education

1997 University of Virginina - B.Sc. Mathematics & Cognitive Science

1999 Brown University - M.Sc. Cognitive & Linguistic Sciences

2004 Brown University - Ph.D. Applied Mathematics

Research Interests

Currently, my research interests span topics in statistics as well as neural coding and computation, with an emphasis on questions raised by large-scale neurophysiological data sets, and their implications for our understanding of the dynamics and functional properties of neuronal circuits.
