Hi, my name is Artem Aguichine, and I am currently an Associate Professor at the Instituto de Astronomía - Ensenada, UNAM (IA - Ens, UNAM).

I am a planetary scientist, and my research spans a broad range of topics related to planet formation, evolution, and interior structure. I focus on characterizing the properties and composition of (exo)planets through theoretical approaches and numerical modeling.

I am particularly interested in the distribution of volatile species in our Solar System, and the presence of water in sub-Neptunes. My research advances the field of astrobiology, shedding light on the distribution of life throughout planetary systems and the origin of life in our own Solar System.
