Previously, I was a Hubble Fellow in the Kavli Institute for Cosmological Physics at the University of Chicago. I did my postgraduate research at the Department of Astrophysical Sciences at Princeton University. I was an undergraduate at the University of Cambridge, where I was a member of New Hall. I was born in Sri Lanka, a beautiful island in the Indian Ocean.

Research interests: Theoretical and observational cosmology, cosmic microwave background, large-scale structure, early universe theoretical physics, stellar dynamics, galaxy evolution, statistical methods, optimal numerical algorithms.

I recently joined UCL as a STFC Ernest Rutherford Fellow. I got a PhD in 2011 at the Universitat de Barcelona, and since then I have worked as a postdoc at the University of Zurich (2011-2013) and at Lawrence Berkeley National Lab (2013-2016). In the last few years I have been heavily involved in the analysis of quasars and Lyman alpha forest data from the BOSS collaboration, and in the forecast of ongoing (eBOSS) and future surveys (DESI).

Research interests: Large scale structure, observational cosmology, dark energy, redshift surveys, quasars, Lyman alpha forest and neutrino effects in the distribution of matter.
