FRANCESCA MARIANI ’91
Honored by USC for Outstanding Teaching

Francesca Mariani, an associate professor in the Keck School of Medicine at the University of Southern California, received the 2023 Associates Award for Excellence in Teaching. This is USC’s highest honor for outstanding teaching.

Serving as the director of USC’s first-of-its-kind master’s program in stem cell biology and regenerative medicine, Mariani also co-directs the California Institute for Regenerative Medicine (CIRM) COMPASS program for aspiring undergraduates and oversees a parallel initiative, CIRM EDUC4, catering to post-graduates. These programs help students prepare for careers in stem cell science through mentoring and hands-on research. Mariani’s own work focuses on the role of stem cells in large-scale cartilage and bone regeneration.

Reflecting on her commitment to student interaction, Mariani says, “Interacting with students is not just about sharing knowledge; it can be a transformative conversation that empowers students to carve meaningful paths in the intricate journey of life.”

ISABEL PLAKAS ’19
Selected by the U.S.-Ireland Alliance as Mitchell Scholar

Isabel Plakas ’19, who is pursuing a master’s degree in nursing at Johns Hopkins School of Nursing, recently became the first Mawrter to receive a George J. Mitchell Scholarship. Plakas was one of only 12 individuals selected to be a 2025 scholar out of nearly 350 applicants.

Named to honor former U.S. Senator George Mitchell’s contribution to the Northern Ireland peace process, the scholarship program is designed to introduce and connect generations of future American leaders to the island of Ireland, while recognizing and fostering intellectual achievement, leadership, and a commitment to community and public service.

Plakas will begin studying addiction recovery at Trinity College Dublin this fall.

“I started doing harm reduction work in 2018, when I studied abroad in Spain through ���ճԹ�’s collaboration with Hamilton College,” she says. “When I returned in the fall, I took

a course by Dr. Anne Montgomery at Haverford that looked at the overdose crisis in the United States, specifically Philadelphia. I learned about harm reduction, which challenged preconceived notions I had about drug use and the war on drugs.”

After graduation, Plakas moved to Boston to do research but found herself unfulfilled.

“I recalled meeting a ���ճԹ� alum named Sarah Mackin (’07) during my senior year at ���ճԹ� who did harm reduction work in Boston. I reached out and began volunteering at the syringe exchange she ran. I will always be grateful that she accepted me into the community and mentored me.”

Plakas soon got a job next door as a harm reduction specialist at Boston Health Care for the Homeless. “During my first week, a nurse told me, ‘You’re either going to love it or hate it, and you’ll know right away,’” Plakas says. “I loved it.”

After three years, Plakas left to go to nursing school at Hopkins, but ���ճԹ� has continued to find her. “I work at Sex Workers Promoting Action, Risk Reduction, and Community Mobilization (SPARC), a drop-in center for female and nonbinary sex workers in southwest Baltimore,” Plakas says. “The team here is incredible, and during an outreach shift last year, I was excited to learn that my coworker Dr. Sangeeta Iyer is also a ���ճԹ� graduate (Class of 2002).”

At Hopkins, Plakas has received the Nursing Scholar Award from the National Association of Hispanic Nurses, and she serves as co-president of Nursing Students for Harm Reduction.
