Research Overview

I work on observations of high redshift supernovae, particularly spectroscopy of them and/or their host galaxies. The candidates are discovered by a dedicated Hubble Space Telescope survey, which also follows the discovered candidates in order to obtain a light curve. Spectra are then obtained using world-class instruments such as the Very Large Telescope to determine the redshift. The main goal of this project is to increase the constraints on dark energy at high redshifts. I also work on observations of nearby transients, particularly novae occurring in the Local Group of galaxies.
