Dr. Butenas received his Ph.D. In Organic Chemistry from the Kaunas University of Technology, Lithuania in 1985. His postdoctoral work at the Institute of Biochemistry, Vilnius, Lithuania focused on developing and synthesizing substrates for serine proteases. His work resulted in the development of a new class of ultrasensitive fluorogenic substrates and methods based on them for the quantitation of serine proteses involved in blood coagulation and fibrinolysis. He joined the Biochemistry Department in 1991 as part of the group led by Dr. Kenneth G. Mann, which investigates processes of blood coagulation and its regulation.
