PhD projects
I am currently looking for PhD students to take on the projects such as measurements of supernova rates in the Dark Energy Survey, discovering supernovae and tidal disruption events in spectroscopic surveys (such as DESI and 4MOST), and studying the light curves and environments of old Type Ia supernovae using space- and ground-based telescopes.
I am a Reader (Associate Professor) 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).
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.
