Patterns of drug-related behavior: role of VTA DA neurons and inhibitory GPCR-dependent signaling
Regional IP and Licensing Associate
Institution and Major:
Marquette University, B.S., Biomedical Sciences, 2017
My projects focus on studying patterns of drug intake as well as the cellular and molecular mechanisms underlying these pathological behaviors. Specifically, mMy graduate research focuses mainly on studying how dopamine neuron signaling in the ventral tegmental area affects intake and responsiveness to drugs of abuse.

Undergraduate or Post-Doc-Bac Research:
What Got You Interested In Research?
I have always been interested in science, and I am naturally drawn to solving problems and answering difficult questions. As an undergraduate, I was encouraged to volunteer in a neuroscience lab in order to explore my interests further. After joining the lab, my passion for neuroscience grew exponentially. I began taking neuroscience classes, and my interest in pursuing a career in neuroscience was solidified.
Why Did You Choose MN?
I chose the University of Minnesota because of the breadth of research being conducted here, along with the warm environment that I experienced when I interviewed. It seemed like a place to grow as a scientist and as a person, surrounded by an endless number of intelligent and supportive faculty and students.
Student Mentor and the Best Advice They Gave:
Janna Moen: She gave me a ton of great advice on how rotations work and the best ways to choose professors with whom to rotate. She also gave me a lot of tips before going to Itasca and moving to the Twin Cities, which made my transition a lot smoother and less stressful!
Favorite Itasca Memory:
My favorite Itasca memory was when the entire class went out on the lake for an afternoon to hang out and relax.
