We are always looking for motivated students with a keen interest
and solid background in the Earth sciences, physics, engineering, or
computer science. Please take a look at some of our recent publications to
give you an idea of current projects, but I like to work with students who think and work
independently and challenge and extend my expertise and
Please consider applying for our program should you be interested
in pursuing a PhD in my research group, and see the
JSG pages for admission
procedures. The (important) Fellowship deadline is December 1 each
If you think this could be a match, please do reach out by email.
