I am a post-doctoral researcher in Machine
Learning at the University
of British Columbia in the
Department of Computer Science. I work in the Laboratory for
Computational Intelligence (LCI) with Nando de Freitas and Kevin
My research is funded through a junior fellowship
from the Canadian
Institute for Advanced Research (CIFAR), within the
Neural Computation and Adaptive Perception (NCAP) programme
led by Geoff Hinton.
I completed my PhD with Zoubin Ghahramani in the
Learning Group at the University
of Cambridge, where I was a Commonwealth
Scholar to the United Kingdom and a member of St
John's College. I am from South Africa, and completed my
previous degrees in Electrical and Information Engineering at the
of the Witwatersrand, Johannesburg.

||We have 2 papers accepted at NIPS 2012. We'll be at Lake
Tahoe discussing: (1) Expectation propagation for
Gaussian process dynamical systems, and (2) Fast
variational inference for non-conjugate GP regression.
|I am one of the organisers of the NIPS 2012 workshop on Bayesian
Optimisation and Decision Making on the 7th December.
|| I'll be attending the 4th
Canadian Science Policy Conference in Calgary.
||Look out for our paper on Spike-and-slab sparisty for
unsupervised learning at ICML 2012 in Edinburgh.
||I will be at the conference of the International Society
for Bayesian Analysis (ISBA) in Kyoto, discussing Large-scale
approximate Bayesian inference for latent Gaussian models.

|| Our paper on Latent Gaussian models for categorical
data has been accepted at AISTATS 2012 - see our
poster at the conference in La Palma, Canary Islands. Paper
