About CV Projects Links Pics

I am a postdoctoral researcher at the Department of Physics and Astronomy at Johns Hopkins University, where I work with Prof. Adam Riess. I am also a research associate at the American Museum of Natural History and a visiting scientist at NYU.

I completed my PhD in 2013 under the supervision of Prof. Dan Maoz from Tel-Aviv University and Prof. Michael Shara from the American Museum of Natural History.

I am interested in constraining the nature of the stellar system that leads to a thermonuclear, or Type Ia, supernova. I do this mainly by measuring the rates of supernovae I discover in both imaging-based surveys (such as the Subaru Deep Field and CLASH) and in galaxy spectra from large-scale spectroscopic galaxy surveys (such as the Sloan Digital Sky Survey).

In 2012, my thesis was one of 12 animated by Jorge Cham of PhD Comics:

As a AAS Astronomy Ambassador, I also take part in public outreach and education by, for example, giving public talks and mentoring high-school students in the Science Research Mentoring Program at the American Museum of Natural History.

In my free time, I write fiction, in Hebrew and English, and read as much as I can. I am also interested in the history, politics, and culture of ancient Rome, political science, and experiencing the world by living somewhere else every once in a while.


Discovering Supernovae in Galaxy Spectra
Supernovae can be discovered in large-scale spectroscopic galaxy surveys, where in some galaxies a supernova will serendipitously explode in the area covered by the spectral aperture.
