Faculty granted tenure, receive promotions - 2020


We would like to extend congratulations to each of these individuals receiving promotion and/or tenure within NDSU Agriculture.

Peter Bergholz

Peter Bergholz, Microbiological Sciences, has been promoted to associate professor with tenure effective August 16. Bergholz’s research addresses microbe interactions with agricultural landscapes. Specific areas include the evolution of enteric microbes in non-host environments, prediction of foodborne pathogen reservoirs on farms, prediction of ecological traits from genome sequences, and assessment of crop microbiome contributions to drought tolerance. He teaches courses in microbial genomics, environmental microbiology, and foundations in microbiology research.

Aaron Daigh

Aaron Daigh, School of Natural Resource Sciences – Soil Science, has been promoted to associate professor with tenure effective July 1. Daigh has established multiple research projects that have led to improvements in soil management practices for the producers of North Dakota. His research program involves managing agricultural lands impacted by salinization (e.g. tillage, drainage, crop rotation) and resource extraction (e.g. brine spill remediation, coalmine reclamation). Additionally, he has established research on agricultural soil heating/drying, drainage water quality, and greenhouse gas emissions. He teaches undergraduate and graduate courses in soil physics.

Englund, David

David Englund, Agribusiness and Applied Economics, has been promoted to senior lecture effective August 16. Englund teaches courses in elements of economics, introductory microeconomics, skills for academic success, ag marketing and national ag marketing I and II. His efforts with the National Ag Marketing Association program have led the NAMA Team in exceptional performance at national competitions, emerging as national champions among top division I schools in 2019. His teaching has been recognized by the North American Colleges and Teachers of Agriculture (NACTA), NDSU Bison Ambassadors, and several NDSU athletes as a “You Make a Difference” honoree.

Andrew Friskop

Andrew Friskop, Plant Pathology, has been promoted to associate professor with tenure effective July 1. Friskop delivers an Extension program relating to management of diseases of economic importance to North Dakota cereal crops which include wheat, barley and corn. He initiated the first corn pathology research program in North Dakota and reported Goss’s wilt as a new disease for ND. He provides co-leadership for the NDSU Eastern Crop and Pest Management School.

Lauren Hanna

Lauren Hanna, Animal Sciences, has been promoted to associate professor with tenure effective July 1. Hanna has primary teaching responsibility for courses on animal genetics, genetic improvement of livestock, data analysis and design of experiments, and writing and communicating in the animal sciences. She has advised and mentored undergraduate students for their degree and in genetic research. Additionally, Hanna has mentored doctoral and master level graduate students since starting at NDSU. Her research program focuses on genetic improvement strategies in livestock with focus on economically important traits and statistical evaluation methods for improved selection decisions by livestock producers.

David Hopkins

David Hopkins, School of Natural Resource Sciences – Soil Science, has been promoted to professor effective July 1. Hopkins has a primary research focus on providing leadership for a program focused on properties and geography of North Dakota soils related to soil productivity. He teaches courses in soil genesis and survey, and interpretation of field soils. He has also taught several spring break field courses with geology and soils faculty as well as introduction to soil science from 1992-2004.

Jeremy Jackson

Jeremy Jackson, Agribusiness and Applied Economics, has been promoted to professor effective August 16. Jackson’s teaching responsibilities include principles of microeconomics, intermediate microeconomics, public economics, and game theory. His research program has focused on public finance, political economy, applied microeconomic theory, and the economics of happiness. He is the founding director of the Center for the Study of Public Choice and Private Enterprise (PCPE).

Brian Jenks

Brian Jenks, North Central Research Extension Center (NCREC), has been promoted to Agricultural Experiment Station specialist effective July 1.  Jenks has specific expertise in weed control in canola, field pea, lentil, chickpea, sunflower, and other specialty crops important to North Dakota agriculture. Research accomplishments include control of perennial weeds such as Canada thistle and common milkweed, work related to tolerance of crops to sulfentrazone, and findings that indicate that wild oats and green foxtail have developed herbicide resistance.

Devan McGranahan

Devan McGranahan, School of Natural Resource Sciences – Range Science, has been promoted to associate professor with tenure effective July 1. McGranahan’s research strives to apply ecological theory in the sustainable management of rangeland ecosystems. His research focuses on wildland fire and interactions with grazing. McGranahan’s teaching responsibilities include courses in plant identification, data analysis and presentation in the R statistical environment, and fire ecology. As part of his graduate student mentorship, he leads the NDSU Wildland Fire prescribed burning program and has developed open-source technologies for measuring fire behavior and tracking livestock responses with GPS collars.

Thomas Peters

Thomas Peters, Plant Sciences, has been promoted to associate professor with tenure effective July 1. Peters provides leadership in the Extension programs for sugarbeet producers, processors, and the sugarbeet industry in North Dakota, Minnesota and eastern Montana. Specific contributions are in the area of weed control with an additional emphasis on cropping systems. Two new weed control challenges to which Dr. Peters has brought special attention have been waterhemp and Palmer amaranth. Peters’ research focus has been on weed control across the sugarbeet cropping system including cultural, chemical and mechanical weed control practices.

Shafiqur Rahman

Shafiqur Rahman, Agricultural and Biosystems Engineering, has been promoted to professor effective July 1. Rahman’s research area focuses on manure and agricultural waste management (biogas and biochar), microbial fuel cells for bioelectricity, water quality from feedlot runoff, monitoring air quality from livestock production facilities, and mitigation of GHG from manure storage using nanoparticles. He teaches in the areas of post-harvest technology, electricity and electronics in agriculture, seminar, and agricultural waste management and utilization.

David Ripplinger

David Ripplinger, Agribusiness and Applied Economics, has been promoted to associate professor with tenure effective July 1. Ripplinger has developed a nationally recognized Extension and applied research program in bio-products/bio-energy economics. The focus of his efforts are on commercial deployment, feedstock assessment, financing, lifecycle analysis, logistics, market analysis and impacts of government policy on bio-based products important to North Dakota. He has published research on biomass production, logistics, producer willingness to grow energy crops, processing economics, and energy policy.

Tara Swanson
