Ph.D., Stanford University Research Interests My main interest is in spike train data analysis, both for single trains and multiple simultaneously recorded neurons. For single spike trains, I have studied diffusion approximations to various integrate-and-fire models, with particular emphasis on the fitting of models to data, comparing the fits of several models, and refining the diffusion approximations. For multiple spike trains, my main interest is in graphical displays such as the snowflake plot and gravitational clustering, along with exploratory methods to find structure in such data.
