I am interested in the floating ice shelves that fringe East Antarctica. My current work is toward building a better understanding of how climatology influences glaciology via oceanography. I also have some experience with the acoustics of gas hydrates and oceanic methane bubbles.

Professional Interests: Antarctic ice shelf dynamics, sea level rise, underwater acoustics, methane hydrates

Note: I will not do your homework for you and I will not respond to emails directing me to a question posed on the Answers forum.
