Research Interests

Dr. Nixon uses neurobehavioral methods and models to examine the acute and chronic effects of alcohol and other drugs. Within her clinical research, her team also explores sex differences, the effects of age, and the import of ethnic/racial minority status.

Because of the complex nature of substance abuse, Dr. Nixon’s work uses comprehensive behavioral assessments including neuropsychological testing, brain electrophysiology (electroencephalography and event-related potentials), and clinical research interviews. In addition to neurobehavioral research, Dr. Nixon has sustained a strong interest in community outreach and education. Her continued commitment to community outreach is reflected in her on-going work focusing on the cognitive, psychological and social concomitants of substance use.
