Robert Kull joined the Marstel-Day team in 2013. For four years he served as the liaison to the Air Force Civil Engineer Center, coordinating various conservation and compliance efforts, including Endangered Species Act (ESA) and National Environmental Policy Act (NEPA) documents. In 2017, Mr. Kull was the principle investigator for a Programmatic Biological Assessment covering 35 federally-listed bird and bat species on 32 Air Force installations.

Prior to joining Marstel-Day, Mr. Kull was a senior project lead for several Navy Environmental Assessments (EAs) and Environmental Impact Statements (EISs), receiving the Chief of Naval Operations Environmental Award in 2010 for his contributions to the Virginia Capes Range Complex EIS and the Navy Cherry Point Range Complex EIS. He has authored and led teams to draft more than 20 Integrated Natural Resource Management Plans (INRMPs) for the US Air Force and Navy. Mr. Kull served for more than 20 years in the Air Force. As chief of the Resource Conservation Division at the Air Force's Center for Environmental Excellence at Brooks Air Force Base in Texas, he oversaw the development of numerous environmental conservation documents, including INRMPs, biological assessments, Endangered Species Management Plans, and Wildland Fire Management Plans. He also served as chief of the Environmental Noise Branch while assigned to Armstrong Aerospace Medical Research Lab, where he helped develop and enhance noise prediction modeling. Under his leadership, the team developed numerous studies of human annoyance, sleep disturbance, noise effects on wildlife, and sonic boom effects models and tools. Through Mr. Kull's leadership, various wildlife noise effects models were developed for the protection of North American species including bighorn sheep, pronghorn, peregrine falcons, caribou, and desert tortoise.

Mr. Kull created NoiseCamp, a program in which participants from all military services learned about the latest noise technologies, future noise effects development requirements, and wildlife conservation efforts. Other previous positions included Air Force representative to the Federal Interagency Committee on Aircraft Noise; panel member for the Conservation Pillar of the Strategic Environmental Research and Development Program; and team chair for Noise and Animals, International Committee on the Biological Effects of Noise. As a member of the Bird/Aircraft Strike Hazard (BASH) Team, he assisted in the development of early versions of the Bird Avoidance Model and provided staff assistance to the Air Force, Navy, Army, National Aeronautics and Space Administration, and Federal Aviation Administration.

Mr. Kull has a BA in biology from the University of the Pacific. He received his MS in biology from the University of North Carolina at Charlotte, where he studied shorebird behavior. He has studied the effects of noise on animals, and he has written articles on environmental soundscapes, a relatively new topic area in the field. He is also a trained facilitator.
