2009: Peter Schweizer. PhD Ohio University (2008). Peter is interested in relationships between watershed landcover, water quality, and fish diversity. Peter developed mixed models to forecast how projected increases in biomass fuel production might influence fish biodiversity in the Midwest. His first paper, which required advanced statistical methods to represent the distribution of fish richness, is in review in Transactions of the American Fisheries Society. Peter is also contributing to research to quantify risk to fishes in marine kinetic turbines with Mark Bevelhimer, Glenn Cada, and Vince Neary.
2001: Annett Sullivan, PhD in Geology, U. of Wyoming (1999) and ORNL Wigner Fellow. Annett developed a spatial reservoir model linked with CE-QUAL2 output to examine the ability of white sturgeon to avoid and, thus, survive, seasonal water quality deterioration in Brownlee Reservoir, near Boise, Idaho. Annett is a hydrologist with the USGS office in Portland, Oregon. Annett's homepage
Summer 2012: Jamie Smedsmo, PhD student Univ. North Carolina, combined downscaled GCM climate data produced by the Climate Change Science Institute (S-C. Kao, B. Naz, Moetasim Ashfaq) with our SWAT model setup for the Arkansas-White-Red river basin (L. Baskaran) to examine the effects of future climate variability on the relative sustainability of winter wheat and switchgrass. Jamie was supported by DOE's Krell Institute Computational Fellowship
Summer 2012: Mike Kelly, PhD student in mathematics, contributed to research in the Roanoke basin, VA. After reviewing studies of spatial optimization and prioritization of decisions relevant to the hydropower industry, such as where to develop new dams, remove existing dams, and provide passage, Mike developed Python tools needed to implement decision tools. Mike is a NIMBioS fellow at the University of Tennessee, Knoxville: (NIMBios page)
Fall 2010: Lin Shi, UG student from Knox College, Illinois contributed to our bioenergy research research at ORNL by developing PATH or structural equation models of fish richness in the Arkansas-White-Red river basin to better understand the direct and indirect influences of land cover on water quality and fish richness.
2009-10: T. Alex Perkins, PhD student from UC Davis conducted research at ORNL as part of the DOE Krell Institute fellowship program. Alex's research sought to understand how juvenile Snake River Chinook salmon use conditional strategies to adopt either a sub-yearling or yearling migration life history. Alex developed a model of life history choice and incorporated this into an age-based population viability analysis model. He developed and applied optimization methods to identify parameters most consistent with the observed proportions in each life histories across spawning areas and years, and summarized his results in a paper to appear soon in Transactions of the American Fisheries Society.
2008: Alexandre Lockhart, MS student from North Carolina State University, participated in the Snake River Chinook salmon project. Alex imputed missing temperatures and contributed to the development of a temperature-driven model for incubation in tributaries and mainstem spawning areas of the Snake River Hell's Canyon reach written in C.

2006: Emmanuel Isang, BS student in microbiology/pre-med at ETSU, conducted a literature search to support a life history analysis of fishes that focuses on the relationship between the number of years between spawning events and other costs associated with spawning, such as parental care and migration.
