I was raised in a small town in northeast Ohio. My parents were either first or second generation Italian-Americans. We had an extended family where my aunts and uncles were like parents, and my cousins were my sisters and brothers. Our motto was family, food, and fun. My parents were never formally educated but they valued it greatly. They instilled a sense of hard work that only a middleclass immigrant family can, while we played and watched sports. My brothers and I worked hard and when we went to college we were expected to get a solid education. I still carry these principles with me today; work hard and have fun doing so.

Our research efforts center on vitamin A and its metabolites, since they are essential skin cells maturation and development. My laboratory is involved with the design of new retinoids that are effective drugs to prevent/treat disease without toxicity. More specifically, my research group designs, syntheses and studies how our UAB retinoids bind to the retinoid X receptors (RXRs) and act as agonist in important signaling pathways. We have used structural biological studies (x-ray diffraction; quantum mechanical and molecular dynamic computational methods), thermodynamic approaches (ITC; DSC), and recently hydrogen-deuterium exchange mass spectrometer (HDX MS) to understand the molecular interactions between retinoids and RXRs.

Our group is most well-known for the design and translational development of UAB30, a Class II UAB rexinoid. UAB30 is now in human clinical trials that are evaluating it for toxicity, pharmacology, and its efficacy as a new drug for cancer prevention. UAB30 is being carefully evaluated by the NCI and UAB clinicians, since it does not cause toxicity associated with other clinically used retinoids. UAB30 does not cause lipid toxicity or have other unfavorable effects on metabolism, yet it is efficacious in preventing cancer derived from epithelial tissues.
I teach a variety of biochemistry courses ranging from metabolic biochemistry (CH460) to protein structure and physical biochemistry methods (CH461/464). I also teach introductory graduate courses on physical biochemistry emphasizing the understanding of the thermodynamics small molecule binding and recognition to macromolecules (CH700).
