Dr. Jacobson’s academic appointment in the Bioproducts and Biosystems Engineering Department at the University of Minnesota is divided between extension (outreach) and research. Research topics that Dr. Jacobson has lead includes: alternative housing systems for pigs, development of manure management practices for the Minnesota pork industry, evaluation of the indoor air quality concerns, energy conservation and lighting efficiencies in dairy and pig facilities, and evaluation of odor control technologies and the development of an odor ratings systems. Since 2001, Dr. Jacobson has been project leader for a six-state air emission monitoring project that measured gases, dust, and odor from commercial pig and poultry buildings. During the 1994-95 academic year, he was a visiting scientist at a research institute in Denmark working on projects involving air quality concerns inside and outside pig facilities. During that year he also participated in a four country (UK, Germany, Netherlands, and Denmark) European Community (EC) research project on monitoring indoor livestock building environments and carried out an indoor air quality (dust) experiment.

Dr. Jacobson has leadership responsibility for the Minnesota’s extension programs in animal housing systems, including farmstead layouts, structural design of buildings, ventilation and environmental control of animal facilities, and the management of manure from animal production operations. He has worked with the various animal species important to the state, including: pigs, dairy and beef cattle, and poultry (broilers, turkeys, & layers) on such important issues as indoor air quality, energy conservation, effective manure management systems, and odor and gas emissions. He has worked with other extension staff, state agency personnel, commodity groups, and private industry representatives to deliver educational programs to a variety of audiences both within and outside of Minnesota.
