Douglas Sims

Dr. Douglas B. Sims has been teaching environmental science at CSN since Fall, 2011. Some of the courses he teaches are environmental science, geography, meteorology and climatology. Dr. Sims received his BA in Anthropology from the University of Nevada, Las Vegas and an MS in Water Resources Management (concentration in soil science) from the Geoscience Department of the same university. Dr. Sims later earned a PhD in Environmental Science with a concentration in soil chemistry at Kingston University, London, United Kingdom.

Dr Sims routinely involves his students in field and laboratory research activities. He believes that by involving his students in real science they become excited about a career in this growing field.

His research interest relate to abandoned mining and their impacts on the wider environment including sediments, water, climate, animal, and human effects. He is interested in the greater environment and how climate change posses possible impacts in hyper-arid regions. He has published many articles in regional and international journals on historic mining, climate change and environmental impacts caused by human activities.
