Rahul Arun (BS ’21, PhD ’25) is currently a Stanback Postdoctoral Fellow in the Division of Geological and Planetary Sciences at the California Institute of Technology (Caltech). His passion for fluid mechanics began in high school and has evolved through his undergraduate and graduate studies at Caltech. Arun's research focuses on geophysical turbulence, which he describes as complex yet visually appealing, playing a crucial role in understanding Earth's atmosphere, oceans, and engineering applications. His time at Caltech has been marked by diverse experiences, from engineering to geophysics, and he appreciates the institution's ability to broaden his academic perspectives. In addition to his academic pursuits, Arun has been involved in Caltech's water polo team and community service, such as cleaning up along the Angeles Crest Highway. This summer, he will further his research at the Center for Turbulence Research at Stanford University, continuing his exploration of turbulent flows.
