University of Nottingham, United Kingdom
Galaxy evolution research with Prof. Meghan Gray and Prof. Frazer Pearce using cosmological simulations. The collaboration continues beyond the fellowship.
Korea Institute for Advanced Study (KIAS), Seoul
Worked with terabyte-scale cosmological simulation data (Horizon Run 5). Built Python pipelines for feature extraction and preprocessing. Published 6 papers on AGN, ICL, and galaxy evolution.
IISER Mohali, India
Developed simulation pipelines and analytical models for galaxy evolution in large-scale structures. Used SQL and clustering algorithms for catalog analysis.
