Eyjafjallajökull, Iceland, August 2016

Hi, my name is David K. Weiss. I'm a 5th year graduate student in planetary geology at Brown. I got my B.S. in geology from the College of Charleston in 2012. You can contact me at David_Weiss@brown.edu.

My research interests include (1) martian impact cratering; (2) the nature of the early Mars climate; (3) the characteristics and geologic history of the martian cryosphere and hydrologic cycle.

My personal interests include wilderness backpacking.

My graduate advisor is Jim Head.

My undergraduate advisor was Cass Runyon.

Check out (1) my peer-reviewed publications;
(2) selected recent talks and conference participation;
(3) google scholar profile;
(4) press on my research.

    I find the unusual double-layered ejecta (DLE) crater morphology on Mars particularily interesting.
    I am also interested in the configuration and dynamics of pore-ice and groundwater in the deep martian subsurface.
