I graduated with a physics degree from Reed College and started the PhD program in Astronomy at NMSU in fall 2018. I am broadly interested in how galaxies form within their larger cosmic ecosystems, consisting of the surrounding circumgalactic medium (CGM), intergalactic medium (IGM), and the so-called “cosmic web” consisting of filaments, nodes, and voids, on scales in excess of a million lightyears. I study the distribution of gas and dark matter in these ecosystems and how this influences galaxy evolution over cosmic time, using both large theoretical simulations and observational data from state-of-the-art telescopes in space and on the ground. Over the years, I have used various techniques to study these problems, including observed absorption lines in background quasar spectra, analyses of cosmological simulation predictions, and special algorithms to infer the large-scale cosmic web structure. I am strongly involved with several data visualization and computational media projects, including the CosmoVis software for visualization and analysis of simulations and the PolyPhy software which estimates the density of the cosmos using an algorithm inspired by the biological “slime mold” organism. My work with this slime mold-inspired project has led to a paper which has been covered by multiple popular science magazines. As of January 2024, I have 3 published and 2 submitted first-authored papers and 1 second-authored paper to be submitted soon. I am also the PI of a Hubble Space Telescope (HST) Archival Research program to map the gas in cosmic filaments out to redshift 0.5 using observations from the Sloan Digital Sky Survey and HST. I have developed collaborations with researchers in and out of astrophysics at different career levels and different institutions from around the world, and am always happy to develop new connections. I am actively involved in mentoring students, peer reviewing journal articles, and volunteering. 

Outside of astronomy, I am involved in student organizations (currently president of the Bangladesh Student Association at NMSU), playing soccer, and playing and composing music. I also love to travel.
