Research Scientist Alumni
Dan received his B.S. in Geology from the University of California at Santa Barbara. Paralleling these studies Dan also worked in a marine and atmospheric fluid dynamics lab directed towards understanding Hydrocarbon and greenhouse gas source to sink relationships. Using novel equipment he monitored natural gas bubble formation at the seafloor, profiled bubble evolution in the water column, and ultimately tracked natural gas fate to the water column and atmosphere. Dan then moved on to the Solomon Marine Geochemistry lab at the UW where he studied pore water fluid flux at active margins using innovative equipment. Most recently he has found his home in the UW Sediment Dynamics group within the oceanography department where he is concentrating his efforts on the ONR funded Mekong River Delta project, specifically sediment accumulation and fate within the mangrove forest of Cu Lao Dung, Vietnam. Dan enjoys getting his hands dirty at work and at play, facilitating both research and daily life, sailing, hiking, biking, and the requisite photography.
