New Resident Highlight: Meet Dermatology Resident Dr. Nathalie Ly!

Nathalie grew up in Sheboygan, Wisconsin in a lively family of eight. She completed her undergraduate studies at the University of Wisconsin–Madison, where she double-majored in Biology and Human Development & Family Studies and earned a Certificate in Global Health. During that time, she developed an early interest in how science and human connection intersect—a theme that has guided her path ever since.

She went on to earn her M.D. from The Ohio State University College of Medicine, where she discovered her passion for dermatology and became involved in research on skin and hair disorders. Dr. Ly spent a year at the University of Minnesota as a Predoctoral Clinical Research Fellow under the mentorship of Drs. Maria Hordinsky and Ronda Farah, studying everything from platelet-rich plasma (PRP) and exosomes to the scalp microbiome.

Outside of medicine, Dr. Ly loves to bake—especially macarons and cheesecakes—and find the next tastiest eats. She also enjoys sharing her Hmong heritage through embroidery and mentoring students from underrepresented backgrounds who aspire to careers in medicine. Dr. Ly hopes to build a career in dermatology that combines her interests in skincare innovation, hair disorders, and community advocacy.

New Resident Highlight: Meet Dermatology Resident Dr. Matt Mahoney!

Matt spent most of his life in Iowa— growing up near Waterloo, earning degrees in biology and theology at St. Ambrose University, and attending medical school at Des Moines University.

He’s spent the last three years in the Twin Cities caring for children while completing a pediatrics residency (also here at the U!) and hopes to bring that same heart to his future work as a pediatric dermatologist.

Matt loves making patients feel seen, heard, and comfortable— because he knows skin concerns can come with insecurities and worries. His clinical interests focus on improving how doctors communicate with patients and expanding access to pediatric dermatology care in rural communities.

When he’s not in clinic, you can find Matt enjoying time outdoors, exploring modern art museums and architecture, visiting local farmers markets, and spending time with his wife, Megan.
