Bio Statement

Curriculum Vitae

I received the required education in medicine and my Ph.D. in Pathophysiology from the Siberian State Medical University in Tomsk, Russia. After teaching as a Lecturer and Senior Lecturer/Docent in the Biomedical Department at the Tomsk State Pedagogical University, I came to the U.S. to pursue my research interest in cancer gene therapy.

In 2000, I joined the Gene Therapy Center, University of Alabama at Birmingham (UAB) and obtained extensive training in adenoviral vector-based gene therapy at Yamamoto laboratory.

As a member of the UAB Division of Human Gene Therapy (2000-2006) I was directly involved in the development of new generations of Conditionally Replicative Adenoviruses (CRAds) for malignant diseases.

My contribution resulted in developing critical elements to improve infectivity and specificity of oncolytic virus therapy and led to significant advances of the utility of adenoviral vectors for various applications of human gene therapy.

I was actively expanding virus-based gene delivery technologies via collaborations in varying clinical applications including cancer and stem cell, regenerative medicine, bone biology, mucosal immunity, diabetes, pancreatitis, and peptide hormone research.

Now my expertise in cancer and gene therapy technologies is employed by the Department of Surgery at the University of Minnesota Medical School. Since joining the Surgery Department group in 2006, I had attained invaluable experience in developing new therapeutic and imaging strategies for pancreatic cancer.

My primary interest lies in the development of new oncolytic-virus based therapeutic and imaging modalities for pancreatic cancer, combination of oncolytic virus with immunotherapy and/or chemo-radiation to establish effective therapies for treatment-resistant cancer, and development of in vivo models of pancreatic cancer.
