I. Pamela Alonso, PhD
Degree: PhD, Drexel University
Advisor: Nicholas Gilpin, PhD
Research: The role of periaqueductal gray-signaling mediating hyperalgesia and sleep disorders during alcohol withdrawal.
Department: Physiology

Sleep related regions vastly overlap with regions associated with motivation, learning and pain. I am interested in using sleep and/or exercise as a behavioral therapy to attenuate hyperalgesia and decrease relapse and excessive drinking. By using slice electrophysiology, in vivo fiber photometry, and combined circuit and pharmacological approaches, I will test whether rescuing alcohol withdrawal hyperalgesia attenuates excessive alcohol drinking and relapse. In addition, I will test whether the circuits associated with alcohol withdrawal hyperalgesia can be normalized by manipulating sleep.

Andrea Jones, PhD

Degree: PhD, Tulane University School of Medicine
Advisor: Nicholas Gilpin, PhD
Research: The role of the melanocortin-4 receptor (MC4R) in chronic inflammatory pain
Department: Physiology

The goal of my research is to determine how the MC4R changes with chronic pain. I am interested in sex- and age-specific differences in the way the MC4R functions within brain circuits associated with chronic inflammatory pain. Additionally, I am interested in the role of alcohol use disorder in the transition from acute to chronic pain.

Sydney Vita, PhD

Degree: PhD, University of Mississippi Medical Center
Advisors: Nicholas Gilpin, PhD and Patricia Molina, MD, PhD
Research: Alcohol exposure exacerbates inflammation and anxiety-like behavior induced by repeated mild traumatic brain injury during adolescence
Department: Physiology

I am interested in the mechanisms through which functional alterations occur from early to chronic periods following mild traumatic brain injury (mTBI), especially during periods of neural development. Furthermore, I am interested in how these alterations accumulate in response to repeated mTBI, and/or are exacerbated by additional insults, such as exposure to alcohol. The overarching goal of my research is to identify potential therapeutics that can preserve or restore brain functions following TBI.

Marcus Weera, PhD

Degree: PhD Purdue University
Advisors: Nicholas Gilpin, PhD
Research: Neural mechanisms underlying substance use and co-morbid disorders.
Department: Physiology

I am interested in elucidating the neural circuits and neurobiological  factors that underlie substance (primarily alcohol) use disorders. Further, my research seeks to understand the neural bases of co-morbid substance use and psychiatric (e.g. post-traumatic stress) disorders, as well as between different types of substance use disorders. The goal of my research is to inform prevention and treatment strategies for substance use and related psychiatric disorders.
