Biography:

Dr. Enger is an Assistant Professor in the Department of Animal Sciences with an 80% research, 20% teaching appointment. Originally from the western US, Dr. Enger received his BS degree from the University of Idaho and then completed a MS degree at Washington State University where his research focused on teat disinfectants. Dr. Enger then moved east to complete a PhD in Dairy Science at Virginia Tech where his research explored the relationship between mastitis and mammary gland growth and development. Dr. Enger has received federal grant funding and served on federal and international review panels. Dr. Enger is an active member of both the American Dairy Science Association and the National Mastitis Council.

Research Focus:

Dr. Enger has led the OARDC Mastitis and Mammary Physiology Laboratory since 2018. The long-terms goals of the laboratory are to reduce the occurrence and impact that mastitis has on mammary gland productivity and delineate fundamental aspects of mammary gland biology that affect mammary gland growth, development, and milk production. Accordingly, the laboratory conducts both in vivo and in vitro applied research that is directly applicable to the dairy industry and basic research investigating fundamental concepts of mammary gland biology and function. The laboratory has 3 key areas:

Identify and apply mastitis abatement practices and tools to reduce disease prevalence, occurrence, and economic losses in lactating and non-lactating cattle.
Delineate and limit how mastitis hinders milk synthesis and secretion and mammary growth and development.
Identify foundational processes of mammary gland growth and development that can be exploited to enhance mammary gland growth, development, and productivity.
