Biography

I am a Senior Lecturer in Astrophysics at the Institute of Cosmology and Gravitation at the University of Portsmouth, as well as a Research Associate at the American Museum of Natural History. In 2013, I received my PhD in Physics and Astronomy from Tel-Aviv University. I then held two postdoctoral research positions at The Johns Hopkins University (2013-2014) and New York University (2014-2016), before moving to the Center for Astrophysics | Harvard & Smithsonian as an independent National Science Foundation Astronomy and Astrophysics Postdoctoral Fellow (2016-2020).

Research Interests

I study supernovae - the explosions of stars - as well as other transient astrophysical phenomena. I use observations (images and spectra) obtained with ground- and space-based observatories and large-scale spectroscopic surveys (such as SDSS and DESI). I am specifically interested in uncovering the nature of the progenitors of Type Ia supernovae, studying these supernovae when they are several years old, and conducting population studies of supernovae in general. I am also working on discovering and characterizing tidal disruption events - flares caused by stars that are ripped apart by super-massive black holes - and the galaxies in which they occur.

PhD research projects available

I am currently looking for PhD students to take on the following projects:

  1. Measuring the rates of Type Ia and core-collapse supernovae in the Dark Energy Survey
  2. Studying the nature of supernovae by analysing optical and near-infrared images of years-old Type Ia supernovae, and discovering new types of supernovae by detecting them in galaxy spectra taken by the DESI and 4MOST surveys
  3. Studying the nature of tidal disruption events by discovering new candidates in the DESI and 4MOST surveys, and studying the galaxies in which these flares appear
