Research I'm a Ph.D. student in Daniel Schindler’s lab examining linkages between terrestrial and aquatic ecosystems, focusing on the role of highly mobile organisms as vectors of nutrients. Most of my work focuses on using stable isotopic methods to determine the effect spawning salmon have on stream ecosystem metabolism, as well as exclusion experiments to investigate the role of brown bears in transferring marine-derived nutrients from streams to riparian areas. I’m also developing photogrammetric and remote sensing methods to quantify stream algal abundance. As a side project, I have been working with Jeff Richey in the School of Oceanography on nitrogen cycle modeling for the Mekong River and estimating the contribution of large tropical rivers to the global methane and nitrous oxide budgets. Prior to joining the Schindler Lab, I received my undergraduate and master’s degrees in Earth Systems from Stanford University (B.S. 1999, M.S. 2001) where my research focused on the conservation of sensitive species in fragmented suburban landscapes. Research and recreational interests then took me to Hawaii where I worked with the labs of Peter Vitousek and Pamela Matson investigating variations in biogeochemical cycling of nitrogen along a mesic to wet precipitation gradient. |
