Scientific Team

The SSTI team has extensive working experience in the biotech/pharmaceutical industry.  Our team has broad experience in medicinal chemistry, drug development and cancer biology to progress our programs into the clinical stages and beyond.

Dennis Fei, Ph.D.

Dr. Dennis Fei is a Senior Principal Scientist at SSTI. His research focused on elucidating the functions of novel oncogenes and how developmental pathways contribute to cancer. Dr. Fei received his Ph.D. degree in Pharmacology and Toxicology at Dartmouth College, and completed his postdoctoral training at National Human Genome Research Institute and Weill Cornell Medicine.

Matthew Knowe, Ph.D.

Dr. Matthew Knowe is a Principal Scientist at SSTI. He developed a novel organocatalyst for the enantioselective desymmetrization of carboxylic acids, and applied these methods towards improved synthesis of biologically relevant small molecules. He also prepared isotopically labeled sterols for use as internal standards in mass spectrometry to assay sterol stasis and metabolism. Dr. Knowe received his Ph.D. degree in Chemistry from Vanderbilt University in the areas of synthetic methodology, catalysis, and total synthesis, and completed his postdoctoral training at Vanderbilt University.

Samir Saleh, M.Sc.

Mr. Samir Saleh joined SSTI as a Chemist. He conducted isotopic labeling of drug analogs and metabolites for metabolic studies, and has over 40 years of experience in medicinal chemistry. Prior to SSTI, he was a Drug Discovery Scientist at Vanderbilt University specializing in the synthesis of small molecules with improved potency, PK properties, and in vivo efficacy. Mr. Saleh received his M.Sc. degree in Chemistry from the Middle Tennessee State University.
