Graeme Aggett
Graeme Aggett, Ph.D. 2005, is an ex-Royal Marine Commando (40 Cdo., 1981-83; 42 Cdo., 1984-87) who left the UK in 1988 traveling to New Zealand and Australia to play rugby. While in New Zealand, Graeme studied for a BSc. (Auckland, 1993) and MSc. (Auckland, 1995), and played for the Auckland University Rugby Football 1st XV.
His main research interests included geomorphology, climatology, GIS, remote sensing, and the application of GI technologies to natural hazard assessment and mitigation. His master's thesis was sponsored by the New Zealand Earthquake Commission (EQC), and assessed the earthquake risk to New Zealand's capital city, Wellington. On completion of his thesis, Graeme moved to the capital to take two-year position as 'GIS Professional' at Victoria University of Wellington. Among other tasks, Graeme worked with Professor Michael Crozier and several graduate students in a landslide research group, and was also involved with Dr. John McKinnon in developing a concept called MIGIS (Mobile Interactive GIS). The aim of MIGIS is to utilize portable GI technologies to enhance Participatory Rural Appraisal (PRA) work and to develop new PRA techniques, aims that were successfully tested during a pilot project at a hill tribe village in Thailand (1997).
Andreas Baas
Andreas Baas was born in Alkmaar, cheese capital of the Netherlands. He obtained his Bachelor and Master degrees at the Department of Physical Geography and Soil Science at the University of Amsterdam, where he worked on a numerical self-organization model for simulating vegetated dune development. He has completed his Ph.D. work looking at the behavior and formation of aeolian sand streamers. His main interests lie in aeolian geomorphology, complex dynamical systems and philosophy of science.

J. Dallas Dishman
Prior to joining the USC Department of Geography, J. Dallas Dishman received his B.A. in Geography from Indiana Purdue University at Indianopolis (IUPUI) in 1992. In late summer of 1994, Dallas said goodbye to Indiana and hoped on the "Southwest Chief" bound for the USC Department of Geography. Upon arrival, Dallas began working very closely with Michael Dear, who as served both his M.A. and Ph.D. supervisor (as well as his sailing instructor). During his residency at USC, Dallas' studies ranged from medical geography to social theory. His Master's work examined the early emergence of digital communities on the Internet and their implications for expanding notions of "gay community." Dishman's doctoral research explored anti-gay violence in the City of West Hollywood using a mixed methodology to model both the quantitative and qualitative aspects of anti-gay hate crime across space and time. He completed his dissertation in 2002. Dallas is currently the Program Director of the David Geffen Foundation in Beverly Hills, where he overseas the Foundation's philanthropic activities in the areas of HIV / AIDS, Civil Liberties, Cultural Arts, Jewish Community Services, and Healthcare. In his spare time, he can be found sailing with his former advisor, rock climbing in the Santa Monica Mountains or cycling along the California coast. Dallas currently lives in Brentwood, California with his partner Dimitri Czupylo (USC Annenberg School, '96) and his dog Trip.

Martin Kammerer
Martin Kammerer specializes in fluvial geomorphology and sediment transport. Working with Dr. Bernard Bauer, his dissertation was a field investigation of spatial performance patterns of sediment transport models when bed roughness was accounted for by stress partitioning. He did his undergraduate work at the University of Heidelberg, Germany, and received his Master's degree from Arizona State University, where he worked on heavy metals in stream sediments under Dr. Will Graf. Martin. He gathered academic experience as faculty member and Chair of the Department of Earth and Environmental Sciences at Whittier College where he taught Environmental Sciences, Physical Geography, Geomorphology, Cartographic Methods, GIS, Physical Hydrology, and Integrated Field Methods. He has been active as a scientific consultant to local government agencies and various non-profit organizations working on stream-channel restoration and naturalization design. He now holds a scientific staff position at the Santa Monica Mountains Conservancy where he continues to work on stream rotation and urban storm water projects. Martin remains a member of the academic research community at USC, holding a post-doctoral research assistant position.
