College of Dental Medicine Student Nikolas Christoffel Connects Future Health Leaders Across Borders
When 130 medical and dental students from around the world arrived in New York City this summer for the fourth annual ICEP Global Academic Immersion Travel (AIT) Conference, fourth-year Columbia College of Dental Medicine student Nikolas Christoffel saw the culmination of six months of planning. Held July 30 through August 3, AIT 2026 brought together students and clinician-scientists for scientific programming, cultural exchange, and relationship building, with Christoffel serving as president of Columbia’s ICEP Global chapter and head organizer of the conference.
The conference was the latest chapter in Christoffel’s involvement with ICEP Global, the International Collaboration and Exchange Program. Founded at Columbia in 2014 by Dr. Anette Wu, MD, MPH, PhD, associate professor of pathology and cell biology at Columbia University Vagelos College of Physicians and Surgeons, ICEP now partners with more than 40 universities across five continents to foster international collaboration among future health professionals.
“The purpose of the program is to build a network of medical and dental students around the world, from some of the top universities in the world, to prepare the future healthcare leaders to collaborate with one another,” Christoffel said. The goal is to “create personal relationships with the idea that when future healthcare threats or challenges arise, such as a pandemic like COVID, healthcare leaders will be able to work together across borders.”
Christoffel was drawn to that mission as a first-year dental student. After missing the opportunity to study abroad as an undergraduate because of the COVID-19 pandemic, he was eager to make international experiences part of his dental education. Through ICEP, he participated in the online program and later spent the summer between his D1 and D2 years conducting biomaterials research at National Taiwan University School of Dentistry. There, he began forming friendships with students from Taiwan and elsewhere.
“I made some really good international connections through this program,” he said. “So I decided to become more involved in it.”
He went on to serve as a senior national student leader and later as Columbia chapter president, eventually leading the AIT Conference in NYC. Organizing the conference meant managing everything from fundraising and accommodations to venues, catering, and recruiting speakers, all alongside the demands of clinic, classes, boards, and residency applications.
The conference brought together participants representing universities across about 13 countries. Its theme, “Sustainable Global Collaboration in Medicine and the Health Sciences for Society,” came into focus during the opening program at the German Consulate in New York, where keynote presentations and a panel explored science diplomacy and how international partnerships can contribute to scientific innovation and advances in health care.
“Transatlantic collaboration, especially between the US and Germany, can help pave the way for increased partnership for scientific innovation and medical advances,” Christoffel said.
Over the following days, participants took part in scientific and cultural programming that included lectures, student presentations, a Model UN debate, and visits to academic and research environments. The scientific program included keynote presentations from Columbia clinician-scientists Dr. Michel Sadelain, MD, PhD, a pioneer in cancer immunotherapy best known for developing CAR T-cell therapy, and Dr. Stephen Tsang, MD, PhD, whose work focuses on inherited retinal diseases and precision therapies.
Christoffel said Sadelain’s presentation was a highlight, offering students valuable advice on pursuing research careers.
For all of the conference’s formal programming, however, the moment Christoffel felt best captured its purpose was much simpler. During a picnic in Central Park, students brought their own food, gathered together, and began talking.
“People connected spontaneously and without any effort,” he said. “I think that showcases the goal of the program. People connect, become friends naturally. And these connections, the hope is that they last a lifetime.”
Christoffel has seen that longevity firsthand. Shortly after the conference, he returned to Taiwan and Japan, where he reconnected with students he had first met years earlier through ICEP. “It’s awesome to know that I have friends and connections through this program around the world,” he said.
Leading AIT 2026 also gave Christoffel an education that extended beyond the dental curriculum. Organizing an international conference required him to navigate different cultures and viewpoints while balancing months of planning with clinic, classes, boards, and residency applications. “This leadership experience and the experience of organizing a conference is very unique and something that can’t really be acquired through a traditional academic program,” he said. “It’s something that you need to step up and voluntarily pursue.”
Looking back on the experience, Christoffel said the work left him with both lasting relationships and a sense of accomplishment. “Ultimately, I think it was a very valuable experience and something that I will always look back on with a lot of pride.”
