I am a member of the astronomy and astrophysics research community, where I conduct galaxy formation and evolution research. I also develop tools for creating, processing, and filtering large volumes of data.

At the CUNY Graduate Center, I am researching semi-analytic model (SAM) of galaxy formation and evolution development, where I am contributing to projects involving Sapphire and the Santa Cruz SAM.

I am also involved in Roman Space Telescope (Roman) preperations, where I developed grism simulation pipelines to create synthetic foreground images.

Below are a selection of first and co-author publications that I was involved with. Please consult my CV for a full detailed list.
