Ryon Graf, Ph.D 

Mission Statement


Time is our most valuable resource in the world, and one for which medical science can grant more for patients: more time with family, more sunsets, and more experiences. To that end, I am passionate about developing technology that can extend both life and quality of life. Day-to-day, I enjoy promoting a work community that is inclusive, collaborative, and purpose-driven. In doing so, I seek to not only add more years of life to patients, but add more life to years, including our own.


Skill Sets

Data Science & Clinical Biostatistics: Application of data science and clinical biostatistics to prospective trial and real-world datasets: data wrangling, data visualization, and statistical inference. Fluent coding in R and KNIME.


Scientific & Strategic Diligence: Evaluation and consolidation of information from published literature, guidelines, press releases, conferences, and regulatory filings to inform strategic decisions through briefs and white papers. Strong written and verbal communication skills.

Publication & Evidentiary Build: Contextualization of aforementioned data and diligence to support strategic product development and evidentiary builds for clinical validity and clinical utility through publication of peer-reviewed scientific literature.
