I'm currently working with the LSST Galaxies collaboration, focusing on stellar population synthesis (SPS) modeling to derive physical properties of galaxies from broadband photometry. You can learn more about this work here. During my Ph.D., I worked on mapping the inner regions of AGN using UV-optical variability and multi-band observations to understand structure and kinematics on sub-parsec scales. I continue to work on interesting projects related to the variability of AGN. Check out this animation for a visual on quasar interiors (courtesy ESO). I'm also a member of the LSST AGN Science collaboration, where I follow developments in time-domain science with AGNs, with the volume of data arriving from the Rubin/LSST. For those new to the field, I've curated a collection of review articles on AGNs — view the collection here.

- Fluent in Python for general programming and scientific computing.
- Use CCDPROC and PHOTUTILS (Astropy affiliated) for optical data reduction.
- Contributor to the ARIES data archive team; developed software for effective data management.
- Extensive use of JAVELIN (MCMC-based) for time series analysis; also familiar with ICCF, DCF, etc. for cross-correlation.
- Developed Astro Tools – a collection of astronomy utilities and scripts.
- Use GitHub for version control and code management.
- Past experience with IDL and some programming in FORTRAN.
- Basic knowledge of HTML/CSS; maintain a couple of static websites.
- Worked with publicly available datasets from:
- Observed using telescopes at ARIES, Nainital:
- Remotely observed using the Thai Robotic Telescope (TRT) network, with telescopes in the USA, Australia, Thailand, and China.
- Developed and maintain an open-source Python pipeline for aperture photometry, specifically tailored to data from these facilities.
- Event Chair for the Young Astronomers' Meet (YAM)-2022, a conference that brought together about 160 Ph.D. students working in astronomy across the country.
- Co-founder of CosmicVarta (2021), a web portal presenting simplified versions of astrophysics research articles for the general public. Managed the website until October 2022 and regularly edited articles from researchers across the country.

Active participant in outreach activities at my institute, including:
- ARIES National Science Day celebration (28th February 2021)
- ARIES e-lecture series during the COVID-19 lockdown (May–June 2020)
A visual glimpse into my travels, nature walks, and everyday scenes that made me stop for a moment—sometimes to take in the light, a quiet street, or just something oddly beautiful. No big plan behind the photos—just things that felt worth noticing and saving.
