François Lanusse
Cosmologist / Astrostatistician @ CNRS, member of the CosmoStat Laboratory near Paris, France.
I am a CNRS researcher working at the intersection between Deep Learning, Statistical Modeling, and Observational Cosmology. I am particularly interested in combining tools and methodologies from the field of Machine Learning (automatic differentiation, deep generative models, score-based high-dimensional inference) with physical modeling for the analysis of Stage IV Cosmological Surveys.
I am currently co-Chair of the LSST Informatics & Statistics Science Collaboration (LSST ISSC) and actively involved in the LSST Dark Energy Science Collaboration (LSST DESC).
Before my CNRS position, I was a postdoctoral fellow at the Berkeley Center for Cosmological Physics (BCCP) and with the Foundation of Data Analysis (FODA) institute at UC Berkeley, working with Prof. Uroš Seljak. Before that, I was a postdoctoral researcher in the McWilliams Center for Cosmology at Carnegie Mellon University, where I was working with Prof. Rachel Mandelbaum on weak gravitational lensing measurements and systematics, and interacted with both Statistics and Machine Learning departments while at CMU.
