Dr. Gregus has over 20 years of experience in academics and the pharmaceutical industry leading and/or supporting cross-functional projects evaluating novel targets for the treatment of chronic pain and other diseases.

Her specific expertise includes pharmacology, neuroscience, biochemistry and drug tolerance in the study of chronic pain in males and females using a variety of behavioral, biochemical and molecular approaches. Her laboratory operates jointly with the Buczynski research group on early-stage drug discovery in pain and addiction.

Education

  • BS, Biology, Villanova University (1998)

  • Assistant Professor, Virginia Tech (2020-   )

Chronic pain affects 30-40% of Americans, most of whom report that their pain is inadequately managed by current treatments.  While opioids are effective for moderate to severe pain, they carry risks of addiction.

Thus, our goal is to elucidate novel molecular mechanisms driving the transition from acute to chronic pain and to translate druggable targets into potential nonopioid therapeutics. In partnership with the Buczynski laboratory (https://www.buczynski-lab.com/home), we utilize a multi-omic approach including advanced mass spectrometry techniques, cell-based assays, and behavioral pharmacology to support early-stage drug discovery.
