Andrea Borges, PhD

Visiting Postdoctoral Scholar

Andrea completed her Bachelor's in Biomedical Sciences at Universidade Federal de São Paulo (UNIFESP) and her PhD in Sciences at UNIFESP, where she focused on global cerebral ischemia in rats. Since 2009, she has been a lab manager in the Department of Psychobiology at UNIFESP. In 2021, she began her postdoctoral training in the same department, working with viral tracers in mice. She joins the Barker Lab on a FAPESP grant to train in application of in vivo electrophysiology to investigation of behavioral flexibility.

Christina Curran-Alfaro, MS

PhD Candidate, Neuroscience

she/her/hers

Christina completed her MS in biology, with a concentration in neurobiology, at Rutgers-Camden in 2020. Her MS thesis work explored circuitry involved in spatial memory utilizing a teleost model. In her doctorate, she is currently using a rodent model to investigate the effects of chronic low-dose ethanol exposure on value-guided decision-making, glutamate receptor subunit expression, and neural correlates which may contribute to aberrant reward seeking.

Laura Giacometti, PhD

Research Assistant Professor

she/her/hers

Laura completed her PhD with Dr. Ramesh Raghupathi in 2018, where her dissertation focused on sex differences in long term behavioral alterations following adolescent mild traumatic brain injury. Her research focuses on sex and hormonal regulation of reward seeking and astrocyte function following chronic drug exposure and HIV infection.

llk34@drexel.edu

Sam Goldberg, MA

Research Assistant

Sam completed his BA in psychology and neuroscience at Denison University and his MA in Applied Psychological Science at Pacific University. He plans to pursue graduate school for neuroscience and explore the integration of neurobiological research with clinical work. He is interested in research involving the neurological impact of substance use disorder.

sg3856@drexel.edu

Kari Haines, PhD

Postdoctoral Scholar

Kari completed their PhD in Addiction Neuroscience at Indiana University Indianapolis. Their dissertation focused on how gonadal hormones influence alcohol seeking and drinking in selectively bred alcohol-preferring rats. In the Barker lab, Kari is expanding their expertise on sex differences in preclinical models of addiction.

kmh533@drexel.edu

Mark Namba, PhD

Postdoctoral Scholar

Mark completed his PhD in Neuroscience under the mentorship of Drs. Janet Neisewander and Foster Olive at Arizona State University, where his primary focus was unraveling neuroimmune mechanisms of motivated behavior and the impact of HIV on cue-induced drug seeking. As a postdoctoral researcher in the lab, Mark is building upon his expertise in behavioral pharmacology and addiction neurobiology by examining the role of glutamatergic and neuroimmune mechanisms in cocaine craving using translational rodent models of comorbid HIV and cocaine use disorders.

mdn54@drexel.edu

Mitch Nothem, PhD

Postdoctoral Scholar

Mitch completed his PhD with Dr. James Barrett in 2020, where his dissertation focused on the effects of peripheral nerve injury and gabapentin on cortical pain processing. His postdoctoral work focuses on the interaction between chronic pain and substance use disorders.

man83@drexel.edu

Jessalyn Pla-Tenorio, PhD

Postdoctoral Scholar

Jessalyn completed her PhD under the mentorship of Dr. Richard J. Noel at Ponce Health Sciences University in Puerto Rico, where her dissertation examined the effects of the astrocytic HIV-1 protein Nef on glutamate transporter expression and cocaine-seeking behavior. As a postdoctoral researcher, she is now investigating how estrogen influences glutamate regulation and contributes to sex-dependent differences in the comorbidity of HIV and cocaine use disorder.

Kylie Volksdorf, BS

Master's Student

she/her/hers

Kylie completed her BS in Biology/Psychology at Loyola University Maryland in 2023. She is currently a Master's student in Drexel's Neuroscience program. Her MS work is currently focusing on investigating how stress disrupts astrocytic glucocorticoid receptors in HIV and cocaine-seeking behavior in a sex-specific manner.

kv463@drexel.edu

Qiaowei Xie, MS

PhD Candidate, Pharmacology and Physiology

Qiaowei completed her MS in Drug Discovery and Development in Drexel University. Now as a PhD candidate in the lab in the Drexel Pharmacology and Physiology program, her research focuses on the effects of HIV infection on cocaine locomotor sensitization and relapse-like seeking behaviors and associated neuronal and peripheral inflammatory mechanism underlying neurobehavioral outcomes of HIV infections in mouse models.
