DeMorrow, Sharon, Ph.D.
Professor of Pharmacology & Toxicology
HDB 3.316

DeMorrow’s research program broadly focuses on the neurological changes associated with either acute liver failure or chronic liver disorders. These alterations range from changes in neuropeptide hormone expression to severe cognitive impairment and hepatic coma (termed hepatic encephalopathy). Determining the signaling molecules released from an impaired liver that may alter brain function is a focus of ongoing studies.

Natividad, Luis, Ph.D.
Assistant Professor of Pharmacology & Toxicology
BME 6.114A

The Natividad laboratory is interested in high-throughput analyses of the neuroproteome to gain insight on the mechanisms of drug and alcohol addiction. Current projects utilize mass spectrometry and in-vivo neuropharmacology to bridge the connection between small molecule/protein signaling in the brain and behavioral dysfunction.


Nixon, Kimberly, Ph.D.
Associate Professor of Pharmacology & Toxicology
BME 6.116A

The Nixon Lab studies mechanisms of neurodegeneration and regeneration in adult and adolescent models of alcohol use disorders. Current projects are focused on the role of adult neural stem cells, microglia and exosomes.
