Short Biography

Dr. Frey conducts research in drug design and teaches medicinal chemistry, pharmacology, toxicology, and molecular biology. Prior to joining the Pharmaceutical Sciences faculty at LIU, Dr. Frey was a Postdoctoral Fellow at Yale University School of Medicine in the department of Pharmacology. At Yale, Dr. Frey received the Ruth L. Kirschstein postdoctoral fellowship from the National Institute of Health to design less toxic anti-HIV agents with improved resistance profiles. In addition to designing antiviral agents, Dr. Frey has worked collaboratively with other scientists in Yale Chemistry and Pharmacology departments to identify novel drug targets for lung cancer and melanoma. Dr. Frey gained experience in drug design, x-ray crystallography, and computational chemistry during her graduate career at the University of Connecticut School of Pharmacy. In collaboration with multidisciplinary scientists, Dr. Frey played a major role in designing novel antibacterial agents for methicillin-resistant Staphylococcus aureus (MRSA) and Bacillus anthracis using drug-target crystal structures. Compounds discovered from her graduate projects are now under a sublicense agreement with Spero Therapeutics, LLC (Cambridge, MA). She is also trained as an x-ray crystallographer and conducts the majority of her data collection research at the National Synchrotron Light Source (NSLS) of Brookhaven National Laboratory. Dr. Frey has authored 23 peer reviewed research articles, 1 invited review, and 1 patent in the fields of medicinal chemistry, structure-based drug design, biochemistry, microbiology, and molecular pharmacology.
