Meet Our Faculty

Bryan J. Sigel, Ph.D. Tulane University

Assistant Professor of Biology
Phone: (702) 992-2617

Bryan J. Sigel is a conservation ecologist interested in how human activities affect biodiversity at multiple spatial scales. He is a California native and received his B.S. from the University of California, Los Angeles in Ecology, Behavior and Evolution. He pursued his doctorate at Tulane University in New Orleans, LA where he studied the effects of forest fragmentation on lowland tropical bird communities in Central America under the direction of Dr. Thomas W. Sherry, and was granted a Ph.D. in Ecology and Evolutionary Biology in 2007.

Dr. Sigel joined the faculty at Tulane University in 2007 as a Visiting Assistant Professor where he taught courses in Introductory Biology and Vertebrate Biology. Following the Deepwater Horizon oil spill in the Gulf of Mexico, Dr. Sigel worked with the Biodiversity Research Institute to assess the impact of the spill on colonial waterbirds. He also pursued research as a postdoctoral fellow with Dr. Caz Taylor at Tulane University, investigating the impacts of the Deepwater Horizon oil spill on shorebird and intertidal invertebrate communities.

Dr. Sigel joined the faculty of Nevada State College in 2012, where he teaches Introductory Biology, Ecology, Conservation Biology, and Statistics, as well as Special Topics courses involving student research.

Jennifer Edmonds, Ph.D., Arizona State University

Assistant Professor of Biology
Phone: (702) 992-2637

Jennifer W. Edmonds is a microbial ecologist with a focus on aquatic ecosystems (streams, wetlands, and oceans), where she asks questions about the role of the good bacteria in providing services for human society, such as removal of excess nutrients and toxic chemicals. Her Ph.D. research at Arizona State University focused on a rural to urban gradient of streams in the Sonoran Desert, and she maintains an interest in the sustainability of desert urban ecosystems. Work with NSC undergraduates includes evaluating how microbial communities in river sediments create hot spots of greenhouse gas emissions, how land-use influences the organic chemistry of our local ponds and streams, and how Lake Mead's water quality is influenced by seasonal variation in microbial activity.

Dr. Edmonds joined the NSC faculty after a post-doctoral position at the University of Georgia and the University of Hawaii, and a position as faculty at the University of Alabama, Tuscaloosa. While she misses riding her moped down to the beach to surf the dawn patrol, Dr. Edmonds finds the beauty of the desert here in the Las Vegas valley an incredible setting for hikes with her family (two daughters and her husband). Dr. Edmonds emphasizes using interdisciplinary approaches to answer basic scientific questions, as well as to address many current environmental concerns here in the valley.
