I recently made the transition from academia into industry.  I am now located in the Bay Area, and work as Quantitative Analyst at Google.

INTERESTED IN DATA SCIENCE? Read the NYT article Looking to the Future of Data Science.
INTERESTED IN STATISTICS? Read the NYT article For today's graduate, just one word: statistics.
What's the difference between the two?  Some answers are here: blog post from USC, and IMS.

From August 2012 to July 2013, I was Assistant Professor in the Department of Mathematics and Statistics(University of Ottawa).  My research interests were:
  • data streaming algorithms, data sketching, and random projection methods; a particular application of interest is real-time monitoring of time series of seismic signals for the purpose of detecting phases of vulcanic activity (interdisciplinary project with the Department of Earth Sciences, University of Oxford)
  • classification and regression trees and random forests for predicting offender risk (interdisciplinary project with the Institute of Criminology, University of Cambridge)
  • Markov chain Monte Carlo (MCMC) convergence assessment and regenerative simulation, with application to Bayesian hierarchical clustering with an unknown number of clusters
  • sequential Monte Carlo (SMC) algorithms and Bayesian methods

Until the end of July 2012, I spent three years as a postdoctoral researcher in the Statistical Laboratory (University of Cambridge).  Previously, I obtained a doctoral degree in statistics from the Department of Statistics (University of Oxford) under the supervision of Dr. Peter Clifford.  I also hold a Bachelor degree in pure mathematics and a Master's in statistics from the Department of Mathematics and Statistics (McGill University).  In both Oxford and Cambridge, I was affiliated to Jesus College as graduate student, and College Research Associate, respectively.
