I am an associate professor at University College London (UCL).  In my research I use tools from probability and mathematical analysis to study algorithms in Statistics and Machine Learning.  The field is often called CSML (computational statistics and machine learning).  I also do some more applied/methdological work in probabilistic modelling, particularly for health applications (see my research page for more).

 

I currently hold an EPSRC New Investigator Award entitled 'Robust and scalable Markov chain Monte Carlo for heterogeneous models'. See here for more details.

​

In 2021 I was honoured to become the first UK recipient of the Blackwell--Rosenbluth award from the International Society for Bayesian Analysis. Press release here.

​

I joined the department of Statistical Science in January 2018, after being a postdoctoral researcher at the University of Bristol, under Christophe Andrieu, as part of the i-like project, and before that a PhD student in Statistical Science at UCL, supervised by Mark Girolami and Alex Beskos. 

​

I believe in Stigler's law of eponymy, and that the concept of multiple discovery/simultaneous invention is more closely aligned with the reality of scientific research than the heroic theory of invention that is dominant in popular culture. That being said, I still have a romantic view of academic life and strive for originality in my work.
