Brief Bio


I received my PhD in 2019 from Clemson University, South Carolina. During my PhD years, I worked on studying the extragalactic background light (EBL) using Fermi LAT observations of active galactic nuclei (AGN) and gamma-ray bursts. I also worked as an instructor of astronomy for a summer school at John Hopkins University, Center for Talented Youth.


I later got the John Bahcall fellowship at University of Wisconsin Madison to study the possibility of AGN being sources of astrophysical neutrinos seen by the IceCube detector. I worked on studying the radio neutrino correlation from AGN during my fellowship. I also worked on simulating the Galactic neutrino signal using a simulation package we developed named SNuGGY.


I am currently interested in using multimessenger + multiwavelength astronomy to explain processes happening inside an AGN. I plan to continue this work, extending to observations from NICER+Fermi-LAT and IceCube, at Goddard as a NPP fellow. I have not given up on Galactic neutrino signals too and plan to extend my simulation study to both high and low energy neutrinos.
