From my early days in Florida, where I split my time between fishing and soccer, to my current pursuits in the field of biochemistry, my journey has been one of passion and discovery.


My fascination with biochemistry took root during my university years, leading me to pursue a Ph.D. at the University of Tennessee, Memphis, under the mentorship of Dr. William L. Taylor. It was here that I honed my skills and deepened my understanding of developmental, molecular biology, and gene function.


Post-graduation, I embarked on a groundbreaking venture using transparent zebrafish as a model for human diseases. Through innovative genetic modifications, I developed transgenic zebrafish expressing green fluorescent protein, enabling real-time monitoring of internal tissues in live animals. This work laid the foundation for my subsequent endeavors.


As an assistant professor, I brought this novel animal model to the University of Cincinnati, forging collaborations with a Fortune 100 company in drug discovery and toxicology research. This experience afforded me invaluable insights into the intricacies of the pharmaceutical industry, from operations to economics.


My research steamed full speed ahead towards exploiting the zebrafish for use in small molecule discovery research applicable to cardiovascular disease, diabetes, and neurodegenerative diseases. During this time I personally witnessed with my own experimentation the central role of nicotinamide adenine dinucleotide (NAD) in controlling pathogenesis for all of these diseases. NAD research perennially yields remarkably positive therapeutic discoveries. The field of NAD biology quickly became a burning passion of mine, where niacin has emerged as distinctly exceptional and therapeutically beneficial in the clinic.


Driven by this newfound passion, I took on leadership roles within the niacin/NAD research community, spearheading initiatives such as themed journal volumes and contributions to advanced nutrition textbooks. Through these endeavors, I discovered my affinity for writing—a skill I have since cultivated and leveraged to advance medical education.  


As a continuing medical education writer, I embrace the role of an unbiased conduit for medical knowledge. I am deeply committed to delivering valuable insights and therapies to medical professionals, paraprofessionals, and patients alike.


In my pursuit of scientific excellence and education, I find fulfillment and purpose—a journey I continue to embark on with enthusiasm and dedication.
