My name is Boris Leistedt — I am a cosmologist in University College London, and you have reached my official academic webpage. Of course, all opinions expressed here are mine, not that of my research group or institution.
Update: I will be joining Camp Hogg in NYU in Sept 2015 to start a Simons Fellowship.

Academic CV: short 3-page version
My research interests span observational cosmology, astrophysics and signal processing. In particular, I develop innovative methods to optimally use cosmological dat sets and address topical fundamental questions like the properties of dark matter, dark energy, and neutrinos. You can look at my publications on ArXiv or my research page if you like to know about my exact research projects.I am a member of the Early Universe @ UCL group lead by Hiranya Peiris, and we have a nice group website earlyuniverse.org detailing our projects, papers and job opportunities. I use LinkedIn and twitter (and other social media) to express my opinions on the hottest news in physics, and stay in touch with other physicists or my friends from engineering school. In my free time I enjoy photography, and I put my favourite pictures on FlickR.

Prior to moving to UCL, I received a “Diplome d’Ingénieur” (engineering degree) jointly from University of Mons (Belgium) and Supélec (France) in the context of a T.I.M.E. scholarship. In parallel I also studied in University Orsay Paris Sud 11 where I received a M.Sc. in Physics in 2011. I did my master’s thesis in Operational Research about the sequential learning of additive decision models, with Prof Marc Pirlot (UMons) and Prof Vincent Mousseau (École Centrale Paris). In 2010 I did an internship in the Astrophysics Department of CEA Saclay where I worked with Dr Anais Rassat, Prof Alexandre Réfrégier and Prof Jean-Luc Starck.
