We tend to think that good genes make us thin and healthy, whereas bad genes make us fat and sick. But what if we could turn our “good” genes on and our “bad” genes off, and improve our overall health by making the right dietary and lifestyle choices? The science of epigenetics suggests we can do just that. In this course, we will start with an introduction to epigenetics, the study of how lifestyle factors can change gene activity without actually modifying the underlying DNA. With that basic foundation in place, students will discover how food is a powerful signal to our genes that can have a positive (or negative) impact on our metabolism, longevity, and mental wellbeing. Specifically, we will explore basic concepts in nutrigenomics, the study of how gene expression can be modified by certain nutrients and bioactive food compounds. We will have live Q&A sessions with some of the world’s leading scientists in this field, including Professor Randy Jirtle (University of Wisconsin), Steve Horvath (UCLA), and Professor Michael Skinner (Washington State). Using the information covered in this course, students will be able to design a personalized nutrition action plan to positively impact their gene expression.


  • Course sizes are limited.
    You won't have 5,000 classmates. This course's enrollment is capped at 65 participants.

  • Frequent interaction with the instructor.
    You aren't expected to work through the material alone. Instructors will answer questions and interact with students on the discussion board and through weekly video meetings.

  • Study with a vibrant peer group.
    Stanford Continuing Studies courses attract thoughtful and engaged students who take courses for the love of learning. Students in each course will exchange ideas with one another through easy-to-use message boards as well as optional weekly real-time video conferences.

  • Direct feedback from the instructor.
    Instructors will review and offer feedback on assignment submissions. Students are not required to turn in assignments, but for those who do, their work is graded by the instructor.

  • Courses offer the flexibility to participate on your own schedule.
    Course work is completed on a weekly basis when you have the time. You can log in and participate in the class whenever it's convenient for you. If you can’t attend the weekly video meetings, the sessions are always recorded for you and your instructor is just an email away.

  • This course is offered through Stanford Continuing Studies.

Lucia Aronica, Lecturer, Stanford Prevention Research Center (SPRC)

Lucia Aronica’s research investigates how diet affects gene activity through epigenetic modifications, and how we can use these modifications to design personalized weight-loss strategies. She is also an adjunct professor of physiology at San Jose State and an advisor for companies active in the personal genomics and self-tracking technology spaces. She has published research papers in Cell, Genes & Development, and the EMBO Journal. Aronica received a PhD from the Universität Wien.
