News

April 2012
I've begun organizing a Computer Vision Reading Group at U of T.  The first meeting will be May 15th.

February 2012
 
Our paper (with Mathieu Salzmann and Raquel Urtasun) "A Family of MCMC Methods on Implicitly Defined Manifolds" will be presented at AISTATS 2012.  Matlab code is available here.

October 2011
I have finished my PhD thesis "Physical Models of Human Motion for Estimation and Scene Analysis" and have started a postdoc with Raquel Urtasun  (Toyota Technological Institute at Chicago) and David Fleet (University of Toronto).  I am now also consulting as Research Associate with Cadre Research Labs.

August 2010
Our paper "A Bayesian Method for 3-D Macromolecular Structure Inference using Class Average Images from Single Particle Electron Microscopy" has been accepted into the journal Bioinformatics.  A preprint of the paper is available here and the project website can be found here.

January 2010
Citation information has been updated for the IJCV article to include the volume, issue and starting page numbers.

August 2009
Three new papers have been made available: "Estimating Contact Dynamics" (ICCV 2009), "Physics-based Person Tracking Using the Anthropomorphic Walker" (IJCV 2010), and "Video-based People Tracking" (In Handbook of Ambient Intelligence and Smart Environments).

Leonid Sigal, David Fleet and I will be running a tutorial for ICCV 2009: "Physics-Based Human Motion Modelling for People Tracking".

Background Information

I am a Postdoctoral Researcher with  Raquel Urtasun  (Toyota Technological Institute at Chicago) and David Fleet (University of Toronto).  I finished my Ph. D. in September of 2011 supervised by David Fleet at the University of Toronto in the Computer Vision group.  I received my M.Sc. and Honors B.Sc. from the University of Toronto in November 2006 and June 2004 respectively.  Though American by birth I am living in Canada by choice, by wife and, more or less, by politics.

Feel free to contact me at the email address above.

Research Interests

My research has looked at the use of physics for tracking human motion.  We began by exploring abstract models of bipedal walking in the context of monocular tracking with particle filters.  More recently we have looked at the dynamics of complex articulated models of the human body in motion estimation and dynamic scene analysis.

I have also investigated the use of Bayesian methods in Electron Cryo-Microscopy with Ryan Lilien, Navdeep Jaitly and John Rubinstein.

Generally, I have a strong interest in machine learning and probabilistic methods, particularly when applied to computer vision related problems.

Hobbies and Other Interests

  • Cooking and food in general.
  • Politics and economics.  I follow the news almost religiously.  I aggregate my news from several sources but favourites include:
  • Rock Climbing.
  • Golf.  I've played off and on all my life but am now getting into it more seriously.
