Research Interests    
Dr. Justice-Bitner’s research has two main areas of focus: G-protein coupled receptor signaling (protein-protein interactions) and resistance of bacteria to natural antimicrobials.

To investigate the role that protein-protein interactions may have in the process of addiction, Dr. Justice-Bitner uses the yeast two-hybrid technique. Dr. Justice-Bitner’s previous research used this technique to discover 3 new proteins that interact with the mu-opioid receptor. She is currently using this same technique to try to uncover more binding partners for the cannabinoid receptor 1 (CNR1 or CB1). This receptor is involved in a variety of physiological processes including metabolism, pain, appetite, and addiction.

To investigate the ability of bacteria to become resistant to natural products, Dr. Justice-Bitner uses a modified Kirby-Bauer method. She has begun testing different essential oils with known antimicrobial activity to see if various species of bacteria can become resistant to the antimicrobial effects of these oils.
