Work experience
Stanford University October 2014 — Present
- Search and characterization of transients in astronomical data: designed and implemented new methods for the search of transients in optical (LSST), gamma-ray (Fermi Gamma-ray Space Telescope) and X-ray (XMM-Newton and Chandra) data:
- doubled the number of Gamma-Ray Bursts detected by Fermi
- found several hundred new transients in Chandra and XMM-Newton data
- developed a new promising transient-finding algorithm for LSST competitive with image-subtraction, but substantially simpler to use
- developed and implemented an innovative Bayesian method for the search of Gravitational Waves counterparts in Fermi data, used by the Fermi collaboration
- Authored several scientific papers on GRBs and electromagnetic counterparts to Gravitational Waves
