Briana M. Mason, Ph.D.

Postdoctoral Fellow

Personal Statement:

I am a current postdoctoral researcher in the laboratory of Dr. Gregory T. Collins. My main goals are to characterize the behavioral responses to drugs that directly or indirectly alter dopaminergic pathways, evaluate drugs that modulate the reinforcing effects of illicit substances, and utilize these drugs as potential pharmacotherapies to reduce the reward-related behaviors associated with repeated drug administration.

My current work will contribute valuable knowledge in substance use disorder research, as well as provide novel directions in substance use disorder treatment.
