Biography:
Sridhar Gajendran obtained his Ph.D. in astronomy from National Tsing Hua University (Taiwan) in 2024, where his research focused on exoplanets and the dynamics of multi-planet systems. He subsequently contributed to the BURSTT project on fast radio bursts (FRBs), and worked on AGN studies using JWST data, at ASIAA in Taiwan, before moving to NCRA as a post-doctoral fellow in 2025. He is currently working on optimizing the SPOTLIGHT pipeline for FRB detection and analysis.Research description:
My research interests span exoplanets, fast radio bursts (FRBs), and active galactic nuclei (AGNs), unified by a broad curiosity about the astrophysical processes shaping our Universe. During my Ph.D. at National Tsing Hua University in Taiwan, I focused on exoplanetary systems, studying the statistical patterns of planetary occurrence and dynamical interactions in multi-planet configurations. After completing my Ph.D., I transitioned to radio time-domain astronomy as part of the BURSTT collaboration, where I contributed to real-time FRB detection, classification, and localization, including efforts using VLBI techniques. More recently, I have been investigating AGNs using mid-infrared JWST data from the SMILES survey, developing color diagnostics to identify obscured AGNs and studying their evolution and environments across redshift. I am currently a postdoctoral researcher at NCRA-TIFR, where my work with the SPOTLIGHT project focuses on enhancing the real-time FRB detection pipeline and characterizing its performance for transient science.Selected publications:
