Hello! I am a theoretical astrophysicist at the Hebrew University.

Our group currently focuses on Stellar Evolution. Scroll down and also check the research page for more details.

We are looking for students and postdocs to join the group, please email me if you are interested.

Stellar Evolution

Stars evolve through a variety of stages. For example, our sun's envelope will inflate by orders of magnitude to become a red giant, leaving behind a dense white dwarf core the size of the Earth. We study the evolution of various stars, focusing on binary systems where two different stars closely orbit one another and interact.

Exo-planets

The first planet orbiting another sun was discovered in 1995, and thousands more were detected since. In 2018, astronomers have directly imaged a planet during its formation for the first time. We use stellar evolution tools to study planet formation and evolution, focusing on directly-imaged planets.
