Natalia Kurepina, Ph.D, is a Research Assistant Member at the Center for Discovery and Innovation.
Dr. Natalia Kurepina earned her Ph.D in Genetics from the Institute of Molecular Genetics in Russia. She studied genetic determinants for the synthesis of microcins, peptide antibiotics from enterobacteria. She completed her postdoctoral research on the genetics of toxic shock syndrome toxins in Staphyloccocus aureus from Skirball Institute, New York University.
Dr. Kurepina joined Dr. Barry Kreiswirth’s Lab in 1995 and participated in a clinical trial collaborating with the pharmaceutical company “Pathogenesis. Since then, she has been actively involved in numerous scientific projects performed in collaboration with major pharmaceutical companies like Otsuka, Merck, Veratorx, Cubist and Omniome and with TB Alliance (non-profit organization).
Dr. Kurepina’s significant skills in the field of infectious disease helped develop novel bacterial treatment approaches, including anti-bacterial drugs and compounds affecting immune system. In particular, Dr. Kurepina performed in vitro testing of anti-bacterial activity of prospective compounds and analysis of their activity ex vivo (infection of THP1 cell culture followed by drug treatment). The tested bacteria belong to drug-susceptible, MDR and XDR Mycobacterium tuberculosis, MRSA, Klebsiella spp. and other gram-negative and gram-positive (including non-tuberculous mycobacteria) organisms.
Recently, Dr. Kurepina research has focused on the phylogenetic relationship between clinical strains of M. tuberculosis and the evolution of drug resistance and virulence factors. She has analyzed whole genome sequences of over 240 M. tuberculosis clinical strains, studying the correlation between drug susceptibility (including newly developed anti-TB compounds) and mutations in chromosomal genes.
Dr. Kurepina’s work in infectious disease directly benefits the medical research community and also benefits public health issues within the US. She has co-authored 63 scientific publications and presented her work at numerous scientific meetings and conferences. Her research has greatly contributed to the positive developments in Tuberculosis detection and treatment, placing her research contributions on the national, as well as global, agenda.
