Personal profile

Personal profile

I am a Postdoctoral Research Fellow in Astronomy, Department of Physics at Royal Holloway, University of London specializing in time-domain astronomy, working with Dr. Justyn Maund. My research focuses on supernovae (SNe), gamma-ray bursts (GRBs), and the electromagnetic counterparts of gravitational wave events. At RHUL, my research emphasizes investigating the environments and progenitors of supernovae, along with their ejecta morphology. By utilizing simulations, observations from facilities like the Hubble Space Telescope and the Very Large Telescope, and Machine Learning techniques, I aim to deepen our understanding of these cosmic explosions. I also actively contribute to the Gravitational-wave Optical Transient Observer (GOTO) project, which is a state-of-the-art facility for identifying optical counterparts to gravitational waves, tracking afterglows of poorly localized GRBs, and observing infant supernovae and other fast-evolving transients.

I am currently involved in the following international collaborations:

Research interests

 

  • Supernovae and Gamma-ray bursts.
  • Electromagnetic counterparts to gravitational wave events
  • Magnetars and their role in powering different types of transients
  • Machine learning applications in astronomy
  • Instrumentation: Characterization of GOTO Imagers, data quality assurance, and hardware performance tracking

 

Selected publications:

 

 

My Other Scientific Reports:

Transient Name Server (TNS) Reports: Submitted reports showcasing newly discovered transients using the GOTO.

General Coordinates Network (GCN) Circulars.

ePESSTO+ Transient Classification Reports

GOTO-FAST spectroscopic classifications of optical transients.
