Education & Training:

• MD – SUNY Upstate Medical University
• Internship – Internal Medicine, Tufts University School of Medicine / St. Elizabeth’s Medical Center
• Residency & Chief Residency – Dermatology, University of Utah
• Fellowship – Dermatopathology, University of Chicago

Research Interests:

Dr. Duffy’s scholarly work centers on the histopathology and surgical management of melanoma and non-melanoma skin cancers, with particular attention to Mohs surgery outcomes, opioid prescribing practices, and rare cutaneous neoplasms. His investigations span molecular drivers of melanoma metastasis, recurrence patterns in special-site nevi, and clinicopathologic correlations in challenging dermatologic entities.

Publication Trends:

Across more than 40 peer-reviewed contributions, Dr. Duffy has concentrated on three dominant themes: (1) optimizing surgical margins and post-operative care in Mohs and melanoma surgery; (2) delineating histopathologic features that predict biologic behavior in melanocytic and fibrohistiocytic lesions; and (3) describing novel or rare cutaneous presentations—from carcinosarcoma to drug-induced eruptions—to expand diagnostic acumen.

Scientific Awards & Recognition:

• Board Certified – American Board of Dermatology (Dermatology & Dermatopathology)
• Consistently high patient-experience ratings (4.9/5 average over 474 reviews)

Grants & Advising:

While specific grant numbers are not detailed, Dr. Duffy’s extensive publication record and editorial roles imply ongoing extramural or intramural funding. No formal roster of graduate students was provided; he trains residents and fellows in Mohs surgery and dermatopathology.

Laboratory & Clinical Teams:

Dr. Duffy works within the multidisciplinary cutaneous oncology teams at the Huntsman Cancer Institute and University of Utah Department of Dermatology, collaborating with dermatopathologists, medical oncologists, and reconstructive surgeons to deliver comprehensive care for high-risk skin cancer patients.
