About
I am a tenured Professor at St. John's University's College of Pharmacy and Health Sciences and Adjunct Professor at NYU Grossman School of Medicine. A molecular biologist and translational bioinformatician/biocurator with a Ph.D. in Oncological Sciences (University of Utah), I completed a Postdoc at Memorial Sloan Kettering Cancer Center. I have spent over two decades bridging bench science and scalable digital infrastructure. As a long-standing curator, editor, and contributor to the Reactome Pathway Knowledgebase, I am part of the Leadership Team deploying ReactomeAI — an initiative to transform open biomedical pathway knowledge into intelligent, AI-driven tools for clinical diagnostics, drug discovery, and precision medicine.
