Postdoctoral Researchers:

As Director of the Macromolecular and Vaccine Stabilization Center (MVSC) at KU, Professor Volkin supervises many post-doctoral researchers and research associates.      For their contact information, see  http://mvsc.ku.edu.

Research Interests:

 

Lack of stability often limits the use of biopharmaceuticals and vaccines (e.g., proteins, DNA/RNA, virus-like-particles, and viruses) as human medicines.  Loss of potency can occur during manufacturing, storage, or administration.  Our research objective is to understand the changes in physicochemical properties that accompany the loss of biological activity, and to develop new analytical techniques to monitor these changes at the molecular level.  A detailed understanding of the causes and molecular mechanisms of instability will guide the design of more potent and stable biopharmaceutical and vaccine dosage forms. For more information, see our Macromolecule and Vaccine Stabilization Center website at http://mvsc.ku.edu.

 

Professor Volkin joined the Department of Pharmaceutical Chemistry in 2010. He came to KU with 20 years of R&D experience in the vaccine and biopharmaceutical industry (Merck & Co. and Centocor/J&J).  He led groups in formulation development and analytical characterization of vaccines and therapeutic protein drugs.  His groups contributed to the development of dozens of candidates used in human clinical trials, including five vaccines and three monoclonal antibodies now approved for commercial use.  He is co-author of over 110 scientific papers and book chapters and co-inventor on 14 U.S. patents.  He was awarded Fellow status in the American Association of Pharmaceutical Scientists (AAPS) in 2013.
