Alexander Viktorovich Kabanov (russian: link=no, Александр Викторович Кабанов; born 27 March 1962 in Moscow, Soviet Union (now Russia)), is a Russian and American chemist, an educator, an entrepreneur, and a researcher in the fields of drug delivery and nanomedicine.


Biography and career

Kabanov was born in Moscow, USSR on 27 March 1962, in the family of Soviet chemist Viktor A. Kabanov. He graduated from the Faculty of Chemistry of the Moscow State University in 1984, where he also received PhD – Candidate of Chemical Sciences in 1987 and D.Sc. – Doctor of Chemical Sciences in 1990. In 1994 he reallocated to United States to the

of 110. He published over 350 scientific papers and holds at least 36 US patents. He co-founded several pharmaceutical companies including Supratek Pharma Inc., SoftKemo, Bendarex and DelAQUA Pharmaceuticals. He trained over 70 graduate students and postdocs, half of whom are women and underrepresented minorities and 16 became faculty. Kabanov was a founding director of the NIH Center of Biomedical Research Excellence (CoBRE) "Nebraska Center for Nanomedicine" and is the director of the NIH T32 Carolina Cancer Nanotechnology Training Program. He founded the Nanomedicine and Drug Delivery symposium series that has been held annually since 2003. He is the editor-in-chief of the Reviews and Advances in Chemistry (ReACh). He served a director-at-large of the Controlled Release Society (2019–2022), and is the past President (2018–2020) and the chief executive officer of the Russian American Science Association (RASA).
