Dr. Cocucci studies basic mechanisms of membrane trafficking and is interested in how these processes deviate during cancer development when compared to normal cells. His research adopts multiple techniques, including traditional biochemistry, cell biology, and high resolution fluorescent live cell microscopy. Dr. Cocucci’s goal is to define novel targets for cancer therapy and to improve drug delivery, studying the internalization pathways and the mechanisms of endosomal escape adopted by artificial and biological nanovectors.

My interdisciplinary research program is inspired by the metabolic diversity of microorganisms and the vast array of compounds they produce. Working at the interface of chemistry and biology, my group combines approaches in chemistry, biochemistry, bioinformatics, genetics, and systems biology to discover new natural products, identify bioactivity and mode of action, and to decipher the metabolic basis of their biosynthesis. Ultimately, we seek to translate insights gained from our investigations into solutions for modern day challenges facing human health and the environment. These include new antibiotics to counter drug-resistant pathogens, novel herbicides and biocontrol agents to improve pest management and food security, and engineered biocatalysts to facilitate chemical production by green chemistry and industrial biotechnology.

The Chromatin Design Lab develops engineered proteins and biosensors to study chromatin regulation and transcriptional control. We aim to create custom molecular tools, including mutant-selective binders and sensors that recognize specific combinations of post-translational modifications. These approaches will be used to investigate how histone modifications and transcription factors regulate gene expression, and to design new strategies for targeting diseased epigenetic regulation.

Dr. Mefford is interested in the use of active learning to promote student engagement with science and to foster deeper understanding of often controversial topics associated with drug use and addiction. She strives to instill good research techniques to help engrain learning as a lifelong process.
