 Dr. Coksaygan joined the University of Maryland’s Veterinary Resources Department in 2005 to help with development of infectious agent research and complete a residency in Laboratory Animal Medicine.  He has achieved his board certification and continues to support the care of animals utilized in research at the UMB and affiliates.

 Prior to coming to UMB, Dr Coksaygan concentrated on effect of antenatal glucocorticoid treatment on cardiovascular physiology, endocrine physiology and brain metabolism of sheep fetus. He specialized on live animal experimental modeling of human diseases and developmental neuroscience during his fellowship at NIH/NIA. His current research interest is developmental neuroscience and cardiovascular physiology.

He continues his interest in neuroscience research and development of new experimental research models
