Sulem Celina Calderón-García holds a bachelor’s degree in marine biology from the Technological Institute of Boca del Río, Mexico, where she also conducted thesis research at UNAM’s Institute of Astronomy on sporopollenin as a potential contaminant in Martian regolith studies. She is currently a master’s student in Plant Biotechnology at CINVESTAV-IPN, leading a genetic engineering project on crop preservation strategies for space missions, in collaboration with international research institutes in Russia, Japan, and Mexico. Sulem served as the 2024 Student Representative of the Mexican Astrobiology Society, contributes to the Mexican Astrobiology School, and is a member of the Institute of Astrobiology of Colombia.

Ismael Acosta Servetto holds a Bachelor’s degree in Biological Sciences and is a Master’s student in Biophysics within Uruguay’s PEDECIBA programme. He is also completing a bachelor’s degree in Astronomy at the Faculty of Sciences, University of the Republic. Since 2021, he has served as a lecturer and researcher in the Biophysics and Systems Biology Section at the same institution, and he teaches Physics and Astronomy at San Ignacio School in Montevideo. A member of BMSIS since 2019 and OoLEN since 2021, his research focusses on organic remnants in Precambrian and extreme environments, autocatalytic molecule modelling, and the impacts of space weather on life and extinction events.

Karina Rosario Ortiz-Leyra holds a bachelor’s degree in Earth Sciences from UNAM with a specialization in Space Sciences. She conducts research at UNAM’s Institute of Nuclear Sciences, studying the origins of life on early Earth through comparisons with analogues such as Saturn’s moon Titan. Karina is a Fellow of The NoRCEL Institute, an Affiliated Member of Sigma Xi, and a member of SOMA. She has participated in major academic events, including the XIII Astrobiology Congress 2025 and the 1st Colombian Symposium on Astrochemistry. Her work appears in eSPECTRA, and she is active in science communication, mentoring, and teaching at UNAM’s National School of Earth Sciences.

Erick de Carvalho Sampaio is an undergraduate student in Biological Sciences at the Federal Institute of Education, Science and Technology of Ceará (IFCE), currently in his eighth semester. His academic interests include planetary habitability modelling, radiative equilibrium temperature simulations, and astrobiological environments such as alkaline hydrothermal vents. He has been developing a Python-based algorithm to simulate habitable zones and radiative equilibrium temperatures, initially for M-dwarf stars, with plans to expand to other stellar types. Erick has taught short courses on astrobiology and the origins of life, presented scientific posters, and is a member of SBAstrobio and InSpace Group. He is also applying for graduate studies at the University of São Paulo (USP).

Luis Alberto Allccahuaman Huauya is a biologist, holding a bachelor’s degree from Universidad Peruana Cayetano Heredia, and currently a master’s student in Chemistry at the National University of Engineering (UNI). He specializes in the study of tardigrades, covering processes from field sampling and taxonomic identification to the evaluation of their resistance to extreme conditions within the framework of astrobiology research. He is an Associate Researcher at the Peruvian Association of Astrobiology, where he has led experimental projects and contributed to the publication of the first Peruvian study on tardigrade survival following exposure to the stratosphere. He has authored scientific publications in national and international journals, has experience as a scientific peer reviewer, has taught biology at the secondary education level, and is actively engaged in science communication and outreach in genetics, molecular biology, and astrobiology.
