Rutgers University, Ph.D.
Oceanography
2015
I am an oceanographer whose research spans environments from the mid-ocean ridge system to coastal regions. I received my Ph.D. in Oceanography from Rutgers University in 2015. I also hold an M.S. in Marine Science from the University of Georgia and a B.S. in Ocean Technology from the Ocean University of China. Before joining the faculty at CFOS-UAF, I held positions at the Applied Physics Laboratory, University of Washington as a research scientist and at the Woods Hole Oceanographic Institution as a postdoctoral scholar.
- Geological Oceanography
My research integrates numerical modeling and underwater acoustic techniques to investigate ocean and seafloor processes across a wide range of marine environments, from the mid-ocean ridge system to continental shelves. My current and recent work focuses on seafloor hydrothermal systems, examining the dynamics and dispersal of hydrothermal plumes as well as the transport of larvae from benthic communities. I also develop autonomous methods for locating hydrothermal vent sources and acoustic techniques for monitoring and mapping hydrothermal discharge on the seafloor. In addition, my research explores internal wave dynamics and their influence on underwater sound propagation over continental shelves. I develop acoustic remote sensing techniques to characterize marine sediments in support of environmental studies.
