Abrianna Mihalkovic, M.A.

Research Associate

Abby is the 1st lab member! She earned her MA in Psychology (Beh. Neuro.) from the University at Buffalo. Her prior research involved preclinical and clinical investigations of addiction, examining genetic and psychosocial risk factors of substance abuse.

Brianna Cullins, B.S., B.A.

Research Collaborator

Brianna graduated from UNC Charlotte in May 2019 with a B.S in Psychology and a B.A. in Spanish. Prior to joining the lab in fall 2021, she worked at a behavioral health inpatient hospital where she became broadly interested in how external factors can cause changes in the brain that may lead to psychiatric disorders. She plans to earn a Ph.D. in Psychology and pursue a career in academia and research.


Undergraduate Research Assistants

Chase Carter

Chase is a junior majoring in Psychology and is interested in neuroscience because of its ability to explain the mysteries of the human mind. Through the billions of neurons in the nervous system, thoughts and consciousness are created. Neuroscience has the ability to explain the underpinnings of these processes. As we map and learn more of the mind, neuroscience is the path to novel solutions to the many illnesses and imperfections of the brain.

He volunteers in the lab because our research has the potential to determine the neural processes behind addiction. This could aid the millions that face addiction in their daily lives.Expereiencing the consequences of addiction firsthand, motivates him to seek solutions to help people in their battles.


Robby Greenspan

Robby is a junior majoring in Neuroscience. His interest in neuroscience stems from his interest in the complexity of human behavior along with hoping to help find effective methods to solve mental illness. He is excited at the prospect of working with new and exciting research methods like optogenetics to see how he can pursue this hope and passion.

IT MIGHT BE YOU?!

We are actively recruiting for graduate students and postdoctoral fellows.

Interested in investigating "How too much of a "good thing" alters neural circuits and affects future behavior?"

Come work on projects investigating 1) how experience-dependent plasticity in the nucleus accumbens regulates reward processing, with a focus on the consumption of palatable foods and stress modulation of food intake, 2) examine the regulatory role of neuromodulators in hedonic feeding.

If interested, please email Dr. Christoffel with the subject line: "Postdoc Applicant " or "Ph.D. applicant" with a brief description of your goals and experience, CV, and 2-3 references (name and email).

For interested undergraduates, please email with subject “Undergrad Research Interest” to Abby Mihalkovic and cc Dr. Christoffel with the following information: (1) availability (hrs/week), (2) previous related experience, (3) short description of why you are interested in this lab and (4) specify if you are seeking course credit for your time in lab.
