i'm currently a postdoc in the social dynamics group at yahoo! research new york. i received my ph.d. from columbia university's physics department,
studying applications of machine learning to image and network data. please see my
resume for more project and background
information.
this site serves several purposes, from presenting and organizing my current
research and
teaching
efforts to publishing code and tips
that i hope others will find useful. eventually i'd like to get some
mac/linux/unix resources and tutorials posted in an organized format so others
can benefit from the vast amount of time i've spent discovering things.
