Hi! I am a “la Caixa” PhD Candidate in the VLBI Group led by with Dr. José L. Gómez at Instituto de Astrofísica de Andalucía (IAA - CSIC), Granada, Spain.
My research focuses on black hole accretion and relativistic jet formation through very long baseline interferometric (VLBI) observations with mm-wave arrays, such as the Event Horizon Telescope (EHT), GMVA, and the space VLBI missions like RadioAstron. I am focused on using Bayesian imaging and modeling methods like Comrade.jl to analyze these observations.
PhD Projects
I have been involved in many projects, primarily related to the EHT, but following are the ones which I have led or majorly contributed:
- Imaging and Analysis of 2018 M87* EHT data with Comrade.jl (Led the analysis with Comrade.jl with Dr. Paul Tide)
- Measuring the Ellipticity of M87* with the 2018 EHT data (Led the EHT Official Project with Dr. Ilje Cho)
- Developing a pipeline to evaluate if movies (from synthetic data) produced by different VLBI imaging softwares are “good movies”.
- Full Stokes Snapshot Modeling of EHT SgrA* data with Comrade.jl
- Imaging of relatistic jets with Comrade.jl

Background
Before joining IAA, I graduated with a Bachelor’s and Master’s in Physical Sciences from the Indian Institute of Science Education and Research Kolkata in July 2022. For my Master’s thesis, I started working with Dr. Gómez during the academic year 2021-2022 to study relativistic jets of supermassive black holes by analyzing multi-frequency VLBA polarimetric observations. I am honored to get funding for this project through the JAE-Intro Scholarship by CSIC, Spain. During my undergraduate years, I worked with Dr. Emilia Järvelä at ESA to study radio emission from narrow-line Seyfert 1 galaxies. I also worked with Prof. Robert Antonucci at the University of California, Santa Barbara, to study the polarization properties of quasars and radio galaxies.
