Assistant Clinical Professor of Epidemiology (Microbial Diseases)
Biography
Dr. Brackney is an Assistant Scientist at the Connecticut Agricultural Experiment Station and Adjunct Assistant Clinical Professor of Epidemiology. He received his degree in Microbiology, Immunology and Pathology from Colorado State University in 2007 with an emphasis in arbovirology and vector biology. After post-doctoral fellowships at the University of New Mexico and Colorado State University, he moved with his family to the New Haven area in 2014 to join the Experiment Station. His laboratory is interested in understanding the cellular and molecular mechanisms mediating arbovirus-mosquito midgut interactions in hopes of identifying critical factors that can be targeted for novel control interventions.
