Michael Kemp Nation MD’81, 80, died Oct. 4, 2025. He practiced pediatrics in the Twin Cities for more than three decades.

Born in Indianapolis, Dr. Nation earned both Bachelor of Arts and Bachelor of Science degrees at Washington and Lee University, where he organized protests against the Vietnam War—a reflection of his lifelong belief in peace and social justice. He began teaching high school science while completing a master’s degree in biology from Wesleyan University. His love of learning and compassion for others led him to Brown, and then the University of Minnesota to complete his pediatrics residency. There he met the love of his life, Janet, a nursing student assigned to the same patient as he on the maternity ward. They married in 1984.

Dr. Nation spent his entire career at Central Pediatrics in St. Paul, and was a member of the professional staff at Children’s Minnesota Hospital, where he served three terms as chief of staff. He volunteered at Children’s Home Society, providing medical care to babies awaiting adoption. He served on the Park Nicollet Medical Center Community Oncology Institutional Review Board as well as on the board of the Friends School of Minnesota. After retiring in 2015, he volunteered with the Minneapolis University Rotary Club and the Minnesota Landscape Arboretum, and supported numerous humanitarian and environmental organizations.

A devoted father and grandfather, Dr. Nation nurtured his daughters’ sense of compassion and critical thought, filling their childhoods with home-cooked meals, conversations at the dinner table, and long hikes along Minnesota’s North Shore. His legacy is one of peace, intellect, humor, and kindness.

He is survived by his wife, two daughters and sons-in-law, three grandchildren, and five siblings and their families. To honor him, consider cooking a meal for loved ones, pouring a glass of aquavit, laughing at the Sunday comics, vaccinating your children, tending a garden, bringing your spouse coffee in bed, saying hi to a baby, or visiting a museum. Donations in his memory may be made to Children’s Minnesota Hospital, Children’s Home Society and Lutheran Social Service of Minnesota, or The Nature Conservancy.

James Rudolph RES’01, MD, 54, died March 26. He was a professor of medicine and of health services, policy, and practice at Brown University, and the director of the Center of Innovation in Long-Term Services and Supports at the Providence VA Medical Center.

Dr. Rudolph grew up on the south side of Chicago and studied at the University of Illinois at Urbana-Champaign and Loyola University Chicago Stritch School of Medicine, where a mentor in geriatric medicine set the trajectory of his career. He completed his internal medicine residency at Brown and his fellowship in geriatrics at Harvard. There he went on to become director of the VA Boston Geriatric Research, Education, and Clinical Center; clinical director of geriatrics at two hospitals; and director of the VA Patient Safety Center of Inquiry in Delirium. He joined Brown’s faculty in 2015.

Throughout his career, Dr. Rudolph worked to improve the lives of older adults, particularly those affected by delirium and the vulnerabilities of hospitalization and long-term care. He was a founding leader of the American Delirium Society and helped build an international community of clinicians and scientists dedicated to reducing the suffering associated with delirium. During the COVID-19 pandemic, his team’s work studying infections in nursing home residents informed national policy and strengthened protections for older adults.

To colleagues across Brown, Dr. Rudolph was a generous mentor, a thoughtful collaborator, and a leader who delighted in bringing together “nerds who care about older people” to solve hard problems. Just a few weeks before his death, he received the 2026 Dean’s Award for Faculty Research Mentoring from The Warren Alpert Medical School and the Dean’s Award for Excellence in Mentoring in Public Health, making him the first person to receive both honors in the same year. His humility, humor, and unwavering commitment to improving care for older adults shaped the work of Brown’s community and the careers of many who trained with him. His influence will continue through the people he mentored, the collaborations he built, and the patients whose lives were improved by his work.

He is survived by his wife, Maura, their three children, as well as his colleagues and friends. Gifts in his memory may be made to the American Delirium Society and the Helen (Sundall) Goyer RN Memorial Scholarship at Loyola University Chicago, or consider donating blood in his honor.

Americo Esquibies Cutti, MD, MBA, MPH, PMD’29, 61, died May 23. He was a clinical professor of pediatrics at The Warren Alpert Medical School and director of pediatric pulmonology at Hasbro Children’s Hospital.

Born in Peru, Dr. Esquibies Cutti earned his medical degree at the Universidad Peruana Cayetano Heredia in Lima and then served as a volunteer physician in the Peruvian Amazon, providing care to communities with limited access to health services. He later immigrated to Brooklyn, NY, where he completed his pediatrics residency and began his career as a pediatric pulmonologist. He worked at several institutions, including Yale and SUNY Downstate Health Sciences University, before coming to Brown.

Dedicated to lifelong learning, Dr. Esquibies Cutti attained his MBA in health care management from Quinnipiac University and an MPH in biostatistics from SUNY Downstate. As a physician, he was known not only for his clinical skills but also for the profound care he brought to every patient and family interaction. As a mentor, he modeled medicine as both a science and a human calling. He nurtured curiosity and encouraged excellence among a generation of trainees.

Whether tending to his garden or walking along the beach with his dog, Max, Dr. Esquibies Cutti found great peace in nature. He had a deep appreciation for the arts, attending operas, ballets, and theatrical shows. As an avid world traveler, he loved exploring new cultures, sampling diverse cuisines, and connecting with people everywhere he went. Each exciting adventure was an opportunity to create lasting memories alongside his family.

Dr. Esquibies Cutti is survived by his wife, Fabiola Balarezo, MD; two daughters, Sofia Esquibies and Victoria Esquibies MD’29; and two brothers.

Caroline Yowa Tschibelu MD’11, 49, died June 19. She was an emergency medicine physician.

Born in Paris, Dr. Tschibelu earned her undergraduate degree from the University of Massachusetts Boston and completed her residency in emergency medicine at Rutgers University Medical Center in New Jersey.

While Dr. Tschibelu was proud of her medical career, it was her vibrant spirit that truly defined her. She was lively, energetic, and effortlessly stylish, with an infectious smile and a contagious laugh that brightened every room. She approached life with a “glass half full” attitude, finding joy in every opportunity and inspiring those around her to do the same.

Dr. Tschibelu treasured time with family and close friends. She loved discovering new restaurants, traveling to new places, and creating lasting memories over good food, meaningful conversations, and laughter. Her quick wit, sense of humor, and genuine kindness made her the heart of every gathering. She had a remarkable ability to make people feel welcome, valued, and at ease.

She is survived by her husband, William; her daughter; her parents; three siblings; and many relatives and friends whose lives were enriched by her kindness and compassion.

Edward R. Feller, MD, PMD’03, 80, died July 21. He was a distinguished physician, researcher, teacher, and mentor at The Warren Alpert Medical School since 1978.

Born in Brooklyn, NY, Dr. Feller earned his bachelor’s degree from the University of Pennsylvania and medical degree from New Jersey Medical School. He completed internal medicine training at McGill University and a gastroenterology fellowship at Harvard. He developed expertise in endoscopic techniques to visualize the pancreatic and bile ducts and had joined the faculty at Harvard when he was recruited to Providence. He went on to lead the Division of Gastroenterology at The Miriam Hospital for 18 years.

A clinical professor of medical science at The Warren Alpert Medical School, Dr. Feller was passionate in his commitment to medical students and their education. He co-directed the Community Health Clerkship, supervised a weekly journal club at The Miriam for third-year students, and held a secondary appointment in the Brown School of Public Health. In 2002, he left clinical practice in order to spend more time teaching. Most recently Dr. Feller was teaching in the first-year Doctoring program and serving as a faculty adviser. His impact on generations of trainees is evident in the scores of scientific publications and presentations on his CV co-authored with residents and medical students.

Dr. Feller was a seven-time recipient of the Senior Citation, the highest honor a graduating class can confer on a faculty member. He received the W. W. Keen Award from the Brown Medical Alumni Association in 2012, and the Association of American Medical Colleges honored him four times with the Humanism in Medicine Award, which recognizes excellence in mentoring. Perhaps more meaningful than any award are the many alumni who considered him one of the most influential people in their lives, inviting him to weddings, baptisms, bar mitzvahs, and other milestone events long after they’d graduated from Brown.

In his personal life, Dr. Feller was an avid ultramarathon runner, completing 50-mile and 100-mile races in the wilderness. He was a connoisseur of the arts, with a deep appreciation for theater, music, and literature. He is survived by his children, Alexander Feller MD’03 and Sophie Claire Feller, MD; his brother; his nephews and niece; his beloved golden-doodle, Oliver; and countless friends, students, alumni, and colleagues. Dr. Feller was predeceased by his wife, Wendy.

Gifts in Dr. Feller’s memory may be directed to The Warren Alpert Medical School of Brown University, Division of Advancement.
