I am an Assistant Professor of Biomedical Informatics in the School of Medicine at Vanderbilt University. I earned an MD from the UCSD School of Medicine, an SM in Medical Informatics from the Harvard-MIT Division of Health Sciences and Technology, and a PhD in Computer Science from MIT's Computer Science and Artificial Intelligence Laboratory, advised by Pete Szolovits and Staal Vinterbo. I completed my clinical internship at the wonderful Gundersen Lutheran Medical Center (where I learned all of the ways that working on a farm can be harmful or fatal. Such as falling into a manure pit and asphyxiating on the hydrogen sulfide. Or jumping in to rescue that person and suffering the same fate. The third guy usually decides not to jump in.) and a postdoctoral fellowship with Octo Barnett in Harvard's Laboratory of Computer Science at Massachusetts General Hospital. Before switching to computational medicine, my first career was as an optical engineer; I designed and built prototype fiberoptic sensors for aircraft at Science Applications International Corporation and developed the optics for a high-speed optical genetic sequencer at a (now defunct!) startup. My bachelor's degree is in Physics.
Following grad school, where my computer science degree focused on medical machine learning, I was a software engineer at Google, where I worked on unsupervised methods to learn clinically relevant patterns from the thousands of medical books in Google Books and from the mind-bogglingly-massive Google query stream. I also developed the algorithm and prototype for Google Symptom Search, a purely data-driven computational diagnosis engine that uses the entire Web as its input dataset.
My current research interests are in the computational aspects of precision medicine. In particular, I am working on the phenotype discovery problem, which is the effort to infer all existing phenotypes from large amounts of Electronic Medical Record data. I am exploring the use of Gaussian Processes and Deep Learning to do this.
I am/have been funded by generous grants from the Edward Mallinckrodt, Jr. Foundation, and the NIH.
