Stefano teaches Astrostatistics in several european universities (>15 in 9 countries thus far) and he authored the book "Bayesian Methods for the Physical Sciences" (Springer). 2016 IAA fellow. His main astronomical interest is understanding how galaxies and galaxy clusters evolve from an observational point of view and using Bayesian methods. See here

Jessi Cisewski-Kehe

is an assistant professor in the Department of Statistics at the University of Wisconsin - Madison. Her main statistical work is in astrostatistics, approximate Bayesian computation (ABC), and topological data analysis (TDA). The main areas of astronomy that she works in are related to exoplanets, large-scale structure, modeling the IGM using the Lyman- alpha forest, and the stellar initial mass function.

is a researcher of UNC at Chapel Hill, providing statistical expertise to the nuclear physics group. He is the current Vice-President for Development of the IAA, and the founder and chair of the Cosmostatistics Initiative (COIN). Among his contributions to IAA, worth mentioning 2,000 pro-accounts for IAA members sponsored by the web-based latex environment Overleaf, which he personally negotiated with the Company CEO. Finally, he recently published the book Bayesian Models for Astrophysical data, by Cambridge University Press 2017, and his research interests range from applications of machine learning to hierarchical Bayesian models in extragalactic Astrophysics and Cosmology.

Matthew Graham

is a Research Professor at Caltech, and the Project Scientist for the Zwicky Transient Facility. He has been very active in the development of the Virtual Observatory, both through the US NVO/VAO and IVOA, and the field of Astroinformatics. His work centers on the applications of variouss Machine Learnning and statistics tools for the analysis of large sky surveys. He has published a number of important papers, and taught at a number of summer schools and other venues.

David W. Hogg

is the Astronomical Data Group Leader at the Flatiron Institute. His research is computational data analysis, spanning all scales from exoplanets to large-scale structure, employing both Bayesian and classical-statistics techniques. He writes open-source data- analysis software and open-access pedagogical statistics content, and he works on the engineering underlying large astronomical surveys.

He is Head of Astrophysics and a member of the ICIC. He graduated from the Universities of Yale and then Chicago, with a Ph.D. in \u2018Quasi-linear Evolution of Compensated Cosmological Perturbations: The Nonlinear Sigma Model\u2019 before moving to CITA as a postdoctoral fellow and then to Berkeley as Assistant Research Physicist/CfPA Fellow, before his appointment as PPARC Advanced Fellow and then faculty at Imperial College London. He is a named Gruber prize winner with the Planck team.

Vinay Kashyap

is an Astrophysicist specializing in solar and stellar coronae, astrostatistics, and algorithmic tools for the analysis of high-energy astronomical data.

He also leads the Calibration Statistics Working Group of the International Astronomical Consortium for High-Energy Calibration, and the informal Lynx Astrostatistics Working Group, and is a member of several Astrostatistics organizations.

Francois Lanusse

is a CNRS researcher, part of CosmoStat Laboratory at CEA Saclay, where he conducts his research at the intersection between cosmology and machine learning. He was a postdoctoral follow at the Berkeley Center for Cosmological Physics (BCCP) and with the Foundation of Data Analysis (FODA) institute at UC Berkeley. And before that, he was a postdoctoral researcher in the McWilliams Center for Cosmology at Carnegie Mellon University. He did his PhD in the CosmoStat laboratory of CEA Saclay in France.

Ilya Mandel

is a Professor of Theoretical Astrophysics at Monash University, Australia.
