Introduction

I am Chris Siu, a research scientist in the Department of Hydrology and Atmospheric Sciences at the University of Arizona. I am working with Dr. Xubin Zeng and Dr. Armin Sorooshian. My current research is focused on better understanding aerosol-cloud interactions. I got my PhD in atmospheric sciences at Texas A&M University.
