Introducing the 2025 TeachAids Fellows

TeachAids has delivered health education to over 500M people across 82 countries—from children and parents to coaches, teachers, and healthcare providers. Behind this impact is a vast network of interdisciplinary researchers, scientists, industry leaders, and a dynamic group of young professionals who collaborate behind the scenes to make the magic happen.

Among them is a select group of Global Health Fellows—a cohort of early-career individuals who join TeachAids each year through a competitive program launched in 2020. These fellows are chosen for their exceptional commitment to global health, education, and public service. They contribute dynamic energy and perspective, working alongside seasoned experts to support the organization's mission of delivering world-class, accessible health education.

This year, Nandika Chatterjee, Aileen Lê, Lisiane Nemlin, Brandon Nguyen, and Angeline Yu were selected for the 2025 class of TeachAids Fellows. Though they follow a range of academic and professional paths, they share a common goal: to strengthen TeachAids’ work and expand access to vital health education.

Brandon Nguyen is a recent Stanford graduate who majored in human biology with a pre-med focus. A Division I gymnast for five years, he earned a scholarship after starting gymnastics at age six. Now preparing to apply to medical school, he’s drawn to sports medicine and primary care for their unique blend of science, movement, and patient connection.

His path towards medicine began early, shaped by his mother’s work as a diabetic counselor at a county clinic. “I saw firsthand the gratitude her patients had for the care she gave,” Nguyen said. “Witnessing those moments showed me the profound impact that simple compassion can have on someone’s life, and it inspired me to follow a similar path.”

At TeachAids, Nguyen has been working with our design and content teams to adapt video narratives from the Concussion Story Wall into short reels to reach a wide-ranging audience on social media. His work highlights stories from youth, parents, and veterans, helping ensure these compelling lived experiences reach broad and varied audiences.

Contributing to a project with real-world impact reinforces his belief that meaningful work in health care goes beyond a clinical setting.

“I remind myself that the work I do extends far beyond myself,” he said. “Keeping that bigger picture in mind, knowing that my efforts contribute to something greater, fuels my passion and motivates me to keep moving forward.”

Beyond academics and athletics, he’s a visual artist who enjoys sketching and once created a detailed mountain landscape entirely from pen dots.

Aileen Lê is a senior at Stanford, majoring in human biology with a minor in poverty, inequality, and policy. She combines science with social and environmental awareness in her academic and extracurricular pursuits.

“In elementary school, I was a spelling bee kid. Really, my favorite word to spell was responsibility. And I could spell it in two seconds, one second. I still can,” Lê said.

That early love for the word reflects her strong sense of responsibility and purpose in her work today. Whether supporting nonprofit strategy, partnership building, or research at TeachAids, she brings a deep commitment to helping build systems that are fair, sustainable, and centered on improving health equity.

At TeachAids, Lê supports expert advisors with nonprofit strategy, partnership building, and research to grow the organization’s global reach.

“I learned about the many ways you can impact health through multi-sector solutions—not just from a provider perspective, but through education, government, NGOs, even the private sector. That broadened my view of what’s possible,” she explained.

Beyond her professional roles, Lê enjoys upcycling clothes inspired by her grandmother’s sewing skills, exploring art galleries, and sipping matcha at local cafés.

Lisiane Nemlin is a New York-based professional working full-time at McKinsey & Company. Her background in global health, communications, and education continues to shape her approach to consulting and research.

At TeachAids, Nemlin helps translate complex brain science studies into relatable educational messages that enable learners to understand, prevent, and manage brain injuries.

“I work on sharing research from the TeachAids Brain Research Institute of Innovation,” Nemlin said. “It’s an interdisciplinary team of neurologists, neuropsychologists, and learning scientists focused on measuring impact and behavior change. The goal is to make science accessible, not just to college grads like us, but so even my mom could get it. This is imperative because brain research is meant to help everyday athletes and families understand what’s happening with their bodies.”

Her interest in health communication began as a member of her school debate team. “It is quite literally my passion. When I find a new topic, I get obsessed with it and have to research everything about it,” Nemlin said.

In her free time, she enjoys traveling, immersing herself in cultural experiences, and watching movies in theaters with her brothers.

Angeline Yu is a full-time researcher working at the intersection of public health, communications, and equity. She recently earned a master’s in Community Health and Prevention Research at Stanford, where she also completed a bachelor’s in Science, Technology and Society with a biology minor. Her academic achievements include a Cardinal Service notation in recognition of her commitment to public service.

“I have always been interested in medicine and knew I wanted to be a physician from the age of eight when my grandpa suffered from a stroke and I helped take care of him,” Yu said.

As a Global Health Fellow at TeachAids, she supports the team across research, communications, and outreach, contributing to the news blog, supporting the development of accessible educational content, and helping our public relations team shape media strategy. Her work amplifies TeachAids’ mission across local and global communities.

“I never really realized how large the scope of health and medicine was beyond patient-provider care,” she said. “I’m really happy I stayed true to my journey and found ways to make it more multifaceted.”

Outside of work, she’s an avid equestrian and a former member of the Stanford Equestrian Team.

“I love love love to spend time around horses and riding,” Yu said. “Even though my competitive days are over, I still find peace in being with them. It’s the only time the world goes silent and I can just focus on the connection between me and my horse.”

Nandika Chatterjee is a Brooklyn-based journalist and editor who supports the TeachAids media team with communications, content strategy, and outreach. She helps with writing and editing for the news blog and assists in managing back-end media efforts.

She brings a background in political reporting, culture writing, and visual storytelling, and a zeal for clear, impactful communication.

“What draws me to both journalism and public health is the same thing: the power of clear, accurate storytelling,” Chatterjee said. “Whether I’m writing about investigative journalism, global health, or education, I’m always thinking about who the information is for, how it’s being told, and how it can actually make a difference.”

Off the clock, Chatterjee enjoys early morning walks with her dog, weekend hikes, and copious amounts of coffee. She’s rarely without a camera and loves capturing scenes from everyday life.

Together, these TeachAids Fellows are among the youngest members of a vast, multidisciplinary team. They bring energy and fresh perspectives that influence the work of seasoned researchers, all while learning from world-class experts in medicine, education, and technology. Through collaboration across generations and disciplines, they help foster a dynamic environment that strengthens both the organization’s culture and the educational products it develops. More than participants in a program, these fellows are part of an evolving ecosystem—one in which every stage of the journey contributes to the whole.
