Geomorphology and Hydrology
I am the son of an immigrant and the first person in my family to go to college. I had a general interest in the natural environment, but it was not until I had the opportunity to do research as an undergraduate (REU Internship) that I fell head over heels for science. I was blown away by the discovery that our planet changes in significant and observable ways each and every day, and I was hungry to learn why. I have since devoted myself to the study of fluvial geomorphology, where I try to answer questions that might unlock the mysteries of why rivers move, jump, and reshape the landscape. I apply a range of methods and techniques, including GIS analysis, numerical modeling, and field investigations, to understand the controls on geomorphic processes. Current work involves studying the evolution of Amazon rivers, the impacts of tropical deforestation in Borneo, and the role of climate change in enhancing soil erosion.
I am eager to share my passion of geomorphology and have plentiful experience in training and supervising young scientists in their efforts to understand the controls on the physical evolution of the environment.
