My name is Boris Leistedt, I am a graduate student in cosmology at University College London.

Academic CV: short 2-page version
My research interests span observational cosmology, astrophysics and signal processing. In particular, I am interested in developing innovative methods to optimally use cosmological dat sets to 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. You also have a LinkedIn profile, which allows me to stay in touch with my friends from engineering school. I use twitter to stay in touch with the latest programming and geek news, which rapidly propagate there. In my free time I enjoy photography, and I put my favourite pictures on FlickR. Finally, I am part 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.

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 was in the Astrophysics Department of CEA Saclay where I worked on Fast Fourier-Bessel decomposition with Dr Anais Rassat, Prof Alexandre Réfrégier and Prof Jean-Luc Starck.
