Graduate Students

David J. Hoekema "David J. Hoekema (current Ph.D. student)", Since 2011
I am a civil engineer. I have both a bachelor's and master's degree in civil engineering. I received by bachelor's degree in civil engineering from the University of Idaho in 2002 and a master's degree from Boise State University in May 2011. My research focuses on reservoir operations modeling, impacts of climate and water conservation on the water budget within basins. My current research is focused on how climatic variability impacted water resource development in the East Snake Plain from 1870-1928 and how water supply forecasts and market price of crops impacts water supply. I am also a current participant on the East Snake Plain Hydrologic Modeling Committee. When not conducting research, I enjoy participating in engineering outreach activities with youth, coaching, and spending time with my family.

Jungjin Kim "Jungjin Kim (current Ph.D. student)", Since 2011
Hi, my name is Jungjin Kim. Now, I am a Ph.D. student of Biological & Agricultural Engineering. I received my M.S. and bachelor from Environmental Engineering Department at Andong National University, Korea. My M.S. research focused on analysis of BMPs effectiveness on hydrology and non-point source pollutant load for Low Impact Development (LID) application. My research interest include watershed modeling using HSPF, L-THIA, and SATEEC, low impact development (LID), and best management practices (BMP).

Aparna Nayak "Aparna Nayak (current MS student)", Since 2014
I have earned both my bachelor and master degree in Microbiology from Rani Durgawati University, Department Of Post Graduate Studies and Research in Biological Science, Jabalpur, India. During my masters, I have done my dissertation on "Kinetics of alkali cation transport in the wild type, salt tolerant, osmo tolerant strains of Anabaena variabilis". I worked as a Research Assistant, Hash biotech labs India pvt ltd, Chandigarh, Punjab, India facilitated by IIMSAM (Intergovernmental Institution for use of Microalgae Spirulina against Malnutrition), UNO. I also did a job in Pharmaceutical Company, BMW Pharmaco India Pvt Ltd., India. Currently I am doing my Masters in Biological & Agricultural Engineering from Department of Biological and Agricultural Engineering, University of Idaho, Boise. I want to do research that addresses real-world issues in terms of fuel, energy, food, water and contributes to solving environmental problems. As we know that more and more scientists are recognizing that effective environmental problem-solving of this kind depends on a broad interdisciplinary perspective.
