Background

Dr. Serguei Liachenko studied at the Russian State Medical University in Moscow from 1981-1988. He then worked at several institutions in Russian pharmaceutical and biotechnology business. In 1994, he obtained an M.D. and a Ph.D. degree in pharmacology from the Russian Research Center for Bioactive Compounds in Moscow. After relocating to the U.S. in 1995, he completed postdoctoral training at the University of Pittsburgh from 1995-2002. During this time; he received the National Research Service Award from NIH. In 2002, Dr. Liachenko joined the Bio-Imaging Center of Emphasis at Pfizer, Inc. In September 2009, he accepted the position of director of Bio-Imaging at NCTR.

Research Interests

Current research interests include:

  • discovering and developing nonclinical imaging biomarkers of drug toxicity and efficacy using magnetic resonance imaging and spectroscopy.
  • investigating glutamine cycle involvement in neurotoxicity, neurological disorders, and addictive substances abuse
  • elucidating the mechanisms of toxicity using magnetic resonance.
  • continuous improvement of imaging/spectroscopic methods in nonclinical applications.

Dr. Liachenko’s expertise includes:

  • biology
  • pharmacology
  • animal research
  • bio-imaging, magnetic resonance, imaging analysis
  • algorithms development
  • additive (3D printing) and subtractive (3D milling) rapid prototyping.

Dr. Liachenko’s research goals include the development of imaging/spectroscopy biomarkers of toxicity to the stage of formal qualification by FDA, development of MRI toolboxes for routine applications in drug safety research, and elucidation of biochemical pathways of drug addiction using minimally invasive imaging technologies.
