About the expert
Focus: Early cancer detection and prevention via peptide-array technology
Founder of Calvary, a company developing peptide-array technology for early cancer detection in dogs and people. Approaches cancer through neo-antigen patterns from RNA-processing errors, with a comparative-oncology angle that bridges canine and human disease biology. Has a direct commercial interest in the diagnostic and vaccine work discussed; this does not invalidate the content but is worth knowing when reading performance claims.
Why this matters
Translational researcher and inventor focused on early-stage cancer detection in dogs through a peptide-array blood test that reads antibody patterns linked to tumor signaling. Strongest on the dog-cancer early-detection problem and on building affordable diagnostics; less certain on whether his preventive cancer vaccine framing translates into population-level outcomes, and his role as founder of Calvary (the company commercializing the test) means his performance numbers should be read alongside independent veterinary replication as it appears.
