About

From planetary systems to the Milky Way.

I am a Senior Lecturer in the Astrophysics Group of the Department of Physics at Bar-Ilan University, where I lead a research group studying exoplanets, binary stars, and multiple-star systems in their Galactic context. Using large astronomical surveys and spectroscopy, I study how these systems form, evolve, and differ across Milky Way populations, with additional work on compact objects in binary systems.

I am also a research affiliate at the Institute of Astronomy, University of Cambridge.

Before that, I was a postdoctoral fellow at the Astrophysics Group, Cavendish Laboratory, supported by the Blavatnik Cambridge Postdoctoral Fellowship.

Open Positions

Join the group at Bar-Ilan.

There are open opportunities in the group for undergraduate research projects, MSc students, and PhD students interested in exoplanets, binary stars, multiple systems, or Galactic-context astrophysics. To discuss a possible project or position, please get in touch.

Research

Questions I keep coming back to.

01 How do planetary systems vary across Galactic populations?
02 What do binaries and multiple systems reveal about stellar evolution?
03 What empirical clues mark the transition from exoplanets to substellar objects?
04 How can we find hidden black holes, neutron stars, and white dwarfs in large astrometric and spectroscopic datasets?
