Dr. Dornbos has been a faculty member of the Biology Department since 2004. Prior to that time, he worked in the area of crop genetics and agronomy in agriculture industry, holding such roles as Global Head of Seed Production Research, Product Development, and Field Agronomist. In these roles, he was involved in the introduction of the first biotechnology products in agriculture, optimization of seed corn production, and field testing of new corn, soybean, sunflower and alfalfa varieties. Dr. Dornbos maintains a graduate school appointment as Lecturer in Agronomy at Iowa State University in which he teaches summer courses on these topics.
In his spare time, you should expect to find Dr. Dornbos outdoors pursuing one of many hobbies. Spring through fall are focused on gardening, fishing, and road cycling. Winter activities include anything from pond hockey, cutting firewood, ice fishing, to bow hunting. Of course, running and road races occurs year around. David has been happily married for 30+years and has three children … two of which are actively working in biology!
Dr. Dornbos teaches and conducts research in a variety of biological topics roughly consistent with his training in plant biology, particularly plant physiology and biochemistry. Courses he teaches regularly includes Living Systems, Human Population and Global Food Systems, Plant Physiology, Global Health – Environment – and Sustainability, and a capstone course Medical Ethics. He regularly takes interim classes to Cambodia, engaging a variety of food security and development best practices and thinking about how to relate food systems in these unique cultures.
- Application of sustainable food production techniques of developed countries with comparable efforts in Cambodia; optimization of appropriate food production systems for small shareholder farmers through the NGO Genesis Community of Learning and Eden School of Agriculture.
- Measurement of the quantity of carbon dioxide assimilated annually by the greenspace of Calvin College and Pierce Cedar Creek Institute to enable optimization of carbon sequestration efforts through the effective management of land resources.
- Characterizing the physiological advantages of invasive shrub species of southwestern Michigan by assessing photosynthesis and transpiration rates, water and light use efficiencies: common and glossy buckthorn, and autumn olive compared with a number of native shrub species.
- Optimization of methods to control the buckthorn species and autumn olive in southwestern Michigan.
