Research Interests: My research focuses on galaxy evolution, large-scale structure, and the physical connection between galaxies and their cosmic environments, particularly at cosmic noon. Using Lyman-alpha forest tomography, I reconstruct three-dimensional maps of the intergalactic medium as a tracer of the underlying matter distribution, identifying the progenitors of galaxy clusters (protoclusters) and characterizing the cosmic web. I integrate these maps with multi-wavelength imaging and optical-to-infrared spectroscopy to study how environment regulates the baryon cycle, shaping star formation and metal enrichment histories of galaxies. I also develop AI/ML frameworks to mine large astronomical datasets, maximizing the scientific return of current and next-generation surveys.
