Dr. George S. Bullerjahn

Dr. George S. Bullerjahn is a Distinguished Research Professor Emeritus, Biological Sciences at Bowling Green State University and theDirector of the NIEHS/NSF Great Lakes Center for Fresh Waters and Human Health.He earned an A.B. from Dartmouth College in 1977 and a Ph.D. University of Virginia in1984.Dr. Bullerjahn is a molecular biologist and microbiologist whose work is focused on the physiology of aquatic microbial communities.  Specifically, for over 30 years he has studied the physiology and stress responses of cyanobacteria in fresh water and marine environments. More recently, these studies have been applied to understanding the characteristics of bloom-forming toxic cyanobacteria in lakes.  Regarding Ohio watersheds, Dr. Bullerjahn has studied both Grand Lake St. Marys and western Lake Erie.  These ecosystems have been plagued with seasonal toxic cyanobacterial blooms that have severely degraded water quality and yielded significant negative economic impact to the lakeshore regions.  Dr. Bullerjahn’s laboratory has published recent studies demonstrating the likely origin of toxic cyanobacterial species, as well as the nutrient requirements of bloom formation.  Whereas it is well known that phosphorus loadings from agriculture have contributed greatly to the expansion of cyanobacterial blooms, more recently the role of nitrogen in triggering bloom events has become increasingly clear.  In recognition of the work by his students and his collaborators, Dr. Bullerjahn and his colleagues have been awarded funds from the NIEHS and NIH to establish the Great Lakes Center for Fresh Waters and Human Health.

Dr. Justin Chaffin

Dr. Justin Chaffin is the research coordinator at Ohio State University’s Stone Laboratory, a field station on Gibraltar and South Bass Islands in Lake Erie. Research in his lab focuses on cyanobacterial harmful algal blooms in Lake Erie and the environmental factors that promote bloom growth and toxicity. One current research project goal is to develop a forecast for Lake Erie cyanobacterial bloom toxicity that can be incorporated into the NOAA Lake Erie HAB bulletin. A toxicity forecast will help water treatment plants better prepare to remove the toxins and produce safe drinking water. Other projects include understanding the prevalence and environmental factors that promote saxitoxin (a lesser know cyanotoxin) production by benthic and pelagic cyanobacteria, investigations of central basin cyanobacterial bloom, and developing criteria of water quality impairment. Recently completed projects studied the interaction between nitrogen and light intensity in bloom toxicity, the effectiveness of data buoys to track cyanobacterial blooms, nitrogen cycling in Sandusky Bay, and internal loading of phosphorus in western Lake Erie. Dr. Chaffin coordinates a citizen scientist Lake Erie water quality monitoring program where charter boat captains collect data and water samples once a week. He also facilitates visiting scientists who conduct research utilizing labs and research vessels at Stone Lab, and deploy long-term monitoring equipment on the grounds, having assisted with many diverse projects including atmospheric mercury monitoring, PAH and PCB tracking in Lake Erie, fish sampling surveys, and projects relating to birds, bats, and crayfish. Additionally, Dr. Chaffin coordinates Stone Lab’s undergraduate research program and is a certified Merchant Mariner Credential (50 ton Master) (i.e., certified boat captain) by the United States Coast Guard.

Dr. W. Robert (“Bob”) Midden

Dr. W. Robert (“Bob”) Midden earned a PhD in Biochemistry from the Ohio State University in 1978 and began his career in the Department of Environmental Health Sciences at Johns Hopkins University where he helped start a new PhD program in Environmental Chemistry. He came to BGSU in 1987 to join a team building the new PhD program in photochemical sciences and establishing BGSU as a national leader in photochemical sciences research. Since then, he has pursued multiple research interests including bioorganic photochemistry of some of the fundamental processes of carcinogenesis, the development of more effective methods of education at all levels, and now: the chemodynamics of water and soil, especially as it relates to restoring and maintaining water quality in our environment. The recipient of more than $20 million in grants from federal and state agencies and private foundations, he has led multiple intercollegiate teams in efforts to improve education in the sciences, technology, engineering, and mathematics (STEM). Dr. Midden retired from all of his administrative roles in 2019 and now leads a science research group investigating problems that are threatening the environmental welfare and economic vitality of Lake Erie and other Ohio lakes, rivers, and streams. The focus is on improving understanding of the chemical processes in water and soil that determine environmental integrity and ecological health. This includes the development of technology to improve the environmental sustainability of the use of animal waste as a fertilizer for maximizing crop yield.
