I have now moved to the University of Texas at Austin. This webpage will not be maintained. Please visit my new webpage.

About Me

I am an Assistant Professor of Statistics at the University of Texas at Austin, in the IROM Department and the Division of Statistics and Scientific Computation. I obtained my PhD from the Computational and Biological Learning group at the University of Cambridge, and spent two years as a post doc in the SAILING laboratory at Carnegie Mellon University.

Research interests

I am interested in nonparametric Bayesian methods for use in machine learning applications. The nonparametric Bayesian paradigm is an elegant and flexible approach for modeling complex data of unknown latent dimensionality. In particular, I am interested in dependent nonparametric processes -- distributions over collections of measures indexed by values in some covariate space. Such models are appropriate for spatio-temporally variable data, and for sharing information between related tasks. I am also interested in the development of fast and scalable inference algorithms for Bayesian nonparametric models.


Apr 2013 I will be joining the McCombs Business School at UT Austin as an Assistant Professor in Statistics, in August 2013.
Feb 2013 Our paper on dependent random measures has been selected as a Notable Paper at AISTATS. Check out the preprint.
Dec 2012 Our paper on nonparametric time-varying topic models has been accepted at SDM.
Dec 2012 Our paper on parallel inference in Bayesian nonparametric models has been accepted at ICML.
Dec 2012 Check out our paper on slice sampling a class of dependent normalized random measures at NIPS!
Sept 2012 I will be talking about slice sampling for dependent nonparametric models at the ICERM workshop on Bayesian nonparametrics at Brown University.
June 2012 I will be talking about beta processes at the ISBA meeting in Tokyo later this month.
May 2012 Our paper on modeling images using transformed IBPs will be presented at ICML in Edinburgh.
Dec 2011 I will be presenting on "Flexible nonparametric models via restriction" at ERCIM in London
Sept 2011 I have started a post doc at Carnegie Mellon, working with Eric Xing.
March 2011 I will be visiting Hal Daumé III's group at the University of Maryland until August.
