Lucas Lombriser is a lecturer in the Department of Applied Future Technologies and a visiting professor in the Department of Theoretical Physics at the University of Geneva, where he also served as a Swiss National Science Foundation professor. He is a member of the Ethics Commission for Research and Development in Graubünden.

His research focuses on theoretical cosmology and astrophysics, where he investigates dark matter, dark energy and extended theories of gravity with the help of gravitational wave observations and the distribution of matter in the universe.

Lombriser completed his physics studies at ETH Zurich and received his doctorate in 2011 from the Institute for Theoretical Physics at the University of Zurich, with research stays at the University of California, Berkeley and the Lawrence Berkeley National Laboratory. After completing his doctorate, he worked as a postdoctoral researcher at the University of Portsmouth and the Royal Observatory, University of Edinburgh in the United Kingdom before beginning his research in Geneva in 2018 and at the University of Applied Sciences of the Grisons in 2025.

Lombriser is involved in international space missions, including the European Space Agency's (ESA) Euclid space telescope and the ESA and NASA's Laser Interferometer Space Antenna (LISA) gravitational wave observatory. He is co-initiator and coordinator of the ‘Atominterferometer Porta Alpina’ project.

In addition to his research activities, Lombriser also works as a consultant for artificial intelligence, Web3 and software development.
