## Payel Das

## astrophysicist from University of Surrey, UK.

### Biography

P. Das is a UKRI Future Leader Fellow in the Astrophysics Research Group at the University of Surrey. She uses models of the motions and ‘chemical fingerprints’ of stars to reveal the evolutionary histories of galaxies from chemodynamical data of their stellar populations. She is also interested in how we can optimally exploit chemodynamical data using machine-learning tools and non-linear data structures such as trees. With P. Jofre, she was one of the first to use tree structures in chemical evolution studies. P. Das got her Master’s degree at the University of Oxford (UK) and PhD at the Max Planck Institute for Extraterrestrial Physics (Germany).

## Gerry Gilmore

## astrophysicist from University of Cambridge, UK.

### Biography

Gilmore is a professor of Experimental Philosophy. He studied mathematical physics in the University of Canterbury, New Zealand and obtained his PhD in Astrophysics from the Canterbury University. G. Gilmore focuses his analysis in Galaxy structure and evolution, Galactic dynamics and chemical evolution. He has been granted Neils Bohr Lecturer, Argelander Lecturer, Lovell Lecturer, Einstein UNESCO Lecturer, Bedford Lecturer, Chalonge and deVega medals, and is Fellow of major international science academies, including the Royal Society, the Institute of Physics, the NZ Royal Society, Academia Europea, and several others.

He leads major research projects, including the ERC-funded Gaia-ESO Survey, and is UK PI of the ESA Gaia mission, and EC-funded strategy/policy coordination projects including OPTICON and its successor the OPTICON-RadioNet Pilot.

## Xia Hua

## mathematical biologist from Australian National University

### Biography

X. Hua is a lecturer at the Mathematical Science Institute at Australian National University. Her research interests are in biological mathematics and biostatistics, focused on the fundamental rules of evolutionary processes and on developing mathematical tools to apply evolutionary thinking in solving real-world problems. She is one of the recipients of 2019 Discovery Early Career Researcher Award for her work in evolutionary biology. She is also one of the recipients of 2021 Eureka prize for Excellence in Interdisciplinary Scientific Research for her work on language evolution. X. Hua obtained her PhD at the State University of New York at Stony Brook and her Bachelor degree at Fudan University.

## Alejandro Maass

## mathematician from Universidad de Chile

### Biography

He studied Mathematical Engineering at the University of Chile and then moved to France where he obtained the PhD degree at the Institut de Mathématiques de Luminy of Université Aix-Marseille in Marseille. His thesis was focused on the ergodic theory of cellular automata and local entropy theory in topological dynamics. In 2000 he joined the newly created UMI-CNRS Center of Mathematical Modeling (CMM) at University of Chile. Since then, he has been conducting fundamental and applied research in both ergodic theory and systems biology. In 2002 he created the Laboratory of Bioinformatics and Mathematics of the Genome at CMM to provide computational and mathematical tools to solve real life biotechnological challenges from a mathematical perspective. The same techniques developed for bioinformatics motivated ideas in astroinformatics. His work in stimulating scientific cooperation with France was recognized with the distinction “Chevalier de l’Ordre National du Mérite”.

## Kurt Walsen Bluee-Blatter (master student)

## mathematician from Universidad de Chile

### Biography

Kurt is finishing his undergraduate studies in mathematics at the Facultad de Ciencias Físicas y Matemáticas, Universidad de Chile. His interests in mathematics are because everything one learns and uses had to be proven first, and the relevant things mathematics could explain in other fields of science like chemistry and physics made him understand the versatility that mathematics has in science, so he is becoming a mathematical engineer (and taking elective courses in astronomy and informatics) in order to have that versatility and hopefully work for science projects. He is involved in this astronomy project being a mathematician, and so being able to merge both of his favorite fields of science.
