Xiao Hui Tai

I am a Ph.D. student in the Department of Statistics and Data Science at Carnegie Mellon University. My research develops methods for comparing unstructured data, applied to forensics and cybercrime.

I am originally from Singapore and was previously a government statistician at the Department of Statistics, which is part of the Ministry of Trade and Industry.

Research

My thesis is on Forensic Data Matching Problems, advised by Bill Eddy. Briefly, I draw a link between matching problems in forensics, and record linkage in statistics and computer science. I then tackle two problems in detail: predicting if pairs of cartridge cases are fired from the same gun, and matching seller accounts on anonymous marketplaces.

My proposal document is here, and slides are here.
