Research Overview
Much like humans, galaxies reside in a diversity of environments — ranging from low-density voids to densely packed clusters. Just as the environments in which we grow up influence our life outcomes, galaxies are also significantly affected by their surroundings. Over a century of observations have demonstrated that overdense regions of the cosmos — such as galaxy groups and clusters — can influence a galaxy's morphology, gas content, and even its ability to form stars. However, the physical drivers behind these observations are still poorly understood. My research is fundamentally focused on understanding the physics that governs the interplay between cosmic environment and galaxy formation and evolution.
My research
I am primarily an observational astrophysicist; however, my work bridges the gap between observations and simulations to better understand the physical mechanisms that drive galaxy evolution in a diversity of environments. My previous and ongoing research is motivated by several unresolved questions, such as:
