Our research is focused on observational astrophysics:

* Cosmic transients and explosions: Studying the catastrophic deaths of stars, utilizing the most advanced robotic wide-field sky surveys, world-wide ground and space-based facilities. Huge amounts of energy are released within hours in events so bright they are seen from the edge of the Universe. The resulting extreme physical conditions involve huge densities, pressures and temperatures, strong magnetic fields, nuclear and high energy particle reactions, and strong relativistic effects (special and general). These topics are at the forefront of research in high energy particle astrophysics and gravity theories, with diverse implications from the sources of life to cosmology.
* Instrumentation: Design and construction of astronomical instruments and instrumental concepts. Among our instrumental projects: the W-FAST Schmidt telescopes designed to search for and characterize small bodies in the Kuiper belt and Oort cloud, imaging multiplexer prototypes, high throughput spectrographs for large facilities and a planned wide-field UV space explorer.
* Astronomical algorithms: Development of efficient and optimal algorithms for research. Examples include: the fast de-dispersion measure transform, streak detection using the fast Radon transform, image coaddition and subtraction.
