Doris Stoppacher

Margarita Salas Fellow 2022-2024

PhD in Theoretical Astrophysics 2019 from the Universidad Autónoma de Madrid (UAM, Spain);
currently a “Margarita Salas Fellow” and postdoctoral researcher in a joint project on: “Hidden Figures on
the Sky”: Unveiling the formation and assembly channels of low surface brightness galaxies by studying
them with various numerical models of galaxy formation and evolution; in collaboration with the
Pontificia Universidad Católica de Chile, the UAM, and the Universidad de Sevilla (Spain). Further past
and ongoing projects including: “A semi-analytical perspective on ... “; a series of studies and
publications focusing on different aspects of galaxy formation and evolution using semi-analytical models
(SAMs). She is further a peer-researcher on the “MultiDark-Galaxies” where she also provides support on
the data release, analysis, and handling. Other interests including the galaxy-halo connection and the
“assembly bias” of galaxy and halo formation or in other words: What does shape galaxy properties in the
large-scale environment of the cosmic web? She is further a member of the movement “Astronomers for
Planet Earth (A4E)”, the “Sociedad Española de Astronomía (SEA)”, and an advocate for student mental
health awareness, cultural equity, and inclusion in Astrophysics.

We have room for several outstanding students to join our group at Pontificia Universidad Católica de Chile.

We are looking for:

Young researchers and students who want to realize their full potential and think boldly to search for new approaches to explore the universe.

 Four ways our team at PUC can empower you

  • World-leading research and tuition

  • Freedom to think and explore

  • Challenging projects that will provide visibility and impact

  • Solid prospects
