A Short History

I completed my undergraduate education in Conservation Biology at Arizona State University in 2009, graduating magna cum laude, and earned my Doctor of Medicine (MD) from Ross University School of Medicine in 2016. My medical education and clinical training took me from Dominica to Brooklyn, Washington, D.C., and London, providing exposure to medical practice across diverse communities and healthcare systems.
In 2021, I returned to academia and joined Grand Canyon University, where I am now a Professor of Biomedical Sciences. My teaching has focused primarily on neuroscience, pathophysiology, anatomy and physiology, and medical physiology, and I have been extensively involved in undergraduate research mentorship and curriculum development.
My principal research focus is the Parkinson’s Project, which I co-lead with Maurice Jabbour, PhD. Our group investigates potential neuroprotective compounds in cellular models of Parkinson’s disease, with current work examining norpsilocin and its effects on cellular viability, apoptotic signaling, and gene expression. This work has contributed to peer-reviewed publication and numerous conference presentations while providing undergraduate students with opportunities to participate directly in biomedical research. I have also co-led interdisciplinary research examining loyalty and prosocial behavior and helped establish the Prosocial Animal Lab, which studies helping behavior in rodent models.
Across my work in biomedical education and research, I have sought to integrate medicine, neuroscience, and mentorship while providing students with meaningful opportunities to engage with the biomedical sciences both inside and outside the classroom.
Outside of medicine and academia, my interests include music performance—guitar, piano, accordion, and vocals—as well as illustration and graphic design, which I have pursued professionally at various points for more than a decade. I also enjoy travel and have explored regions throughout Central and South America, the West Indies, and Europe.
