With more than 135,000 followers on Instagram, Mochammad Rizal has become a leading voice in science communication and evidence-based nutrition in Indonesia.
Through humor, simplicity and storytelling, the registered dietician translates complex nutrition research into accessible, practical tips for everyday life. His growing online reach has opened doors to writing books, speaking at more than 200 events and contributing to national conversations on health and wellness, all while he is pursuing a Ph.D. in nutrition at Cornell.
His research bridges artificial intelligence, precision nutrition and evidence synthesis. Working with the Mehta Research Group, he explores how large language models can support nutrition care, from dietary assessment to personalized meal planning.
Rizal spoke with CHE communications about his work:
Q: What inspired your research?
A: Growing up in Indonesia, I saw people facing anemia, stunting and obesity all at once. These challenges inspired me to explore how technology can bridge the gap between science and real-world needs, making nutrition care more accessible and culturally relevant for everyone.
Q: What impact do you hope your work will have?
A: I hope my work helps redefine how AI is integrated into the practice of nutrition, ensuring that the technology we build is equitable, ethical and centered around people. I want AI to amplify the work of nutrition professionals, not replace them.
I’m grateful to be supported by the Indonesia Endowment Fund for Education (LPDP), which allows Indonesian scholars like me to gain world-class training and return home to contribute to national development. After completing my Ph.D., I plan to bring what I’ve learned at Cornell back to Indonesia to strengthen research, education and innovation in nutrition.
Q: What do you enjoy most about being a graduate student in Human Ecology and DNS?
A: What I love most is the interdisciplinary spirit. Conversations about nutrition here blend seamlessly with data science, public health and human behavior. It constantly reminds me that science isn’t just about algorithms — it’s about people.
As an international student, I’ve also found a strong sense of community here. The warmth and mentorship I’ve received have made Cornell feel like a second home.
Q: What do you enjoy doing outside of your research?
A: I love exploring the natural beauty of Ithaca and New York State — hiking, skiing, kayaking, and visiting farmers’ markets.
Q: Is there a fun or unexpected fact about you?
A: I’m passionate about science communication. My Instagram account started as a small experiment and has now grown into a community of more than 135,000 followers. It’s been rewarding to see how social media can inspire healthier habits and spark curiosity about science.
