Teaching & Mentoring


Dr. Roberto teaches a course titled “The Science and Politics of Food” offered through Penn’s MPH program. This course provides an introduction to the many forces that shape what we eat, including biological, psychological, political, legal, social, and economic. In the course, students discuss and critically evaluate scientific research on food policies designed to improve the world’s diet. The course has a strong focus on the communication of health information and issues of health disparities as they relate to food environments and food policies. In addition, course assignments, activities, and lectures are designed to develop skills related to critiquing research and communicating evidence-based opinions in a clear and compelling manner.


Dr. Roberto is highly committed to mentoring undergraduate, masters, and PhD students and postdoctoral fellows interested in studying behavioral science and policy, with a focus on food and public health issues. The PEACH lab has a diverse group of members with varied backgrounds and interests related to public health and food issues. We meet regularly to discuss PEACH research projects and current events related to food policy. We also have meetings focused on professional development and training opportunities for students such as critiquing journal articles, tips on presenting research, and translating research for lay audiences. The lab also invites outside speakers to share their research with our group. The goal of the lab is to foster a supportive environment for students to voice opinions and learn from and teach one another. Lab members are also encouraged to collaborate with each other on research projects. The lab has a growing network of alumni who have been valuable resources for current members seeking advice about future employment opportunities and career paths. To keep up with our alumni and learn more about their work, sign up for our annual newsletter.

Lab members are expected to commit approximately 8-10 hours per week to a PEACH research project and be active participants in regular lab meetings. Involvement in a PEACH research project can provide opportunities for hands-on research experiences that may include training in experimental and observational research, eating behavior studies, online survey development, IRB correspondence, content analyses, managing and analyzing data, contributing to manuscript preparation, and developing independent research projects.

If you are interested in learning more about practicum or paid opportunities to get involved in the PEACH lab, email the lab manager Sophia Hua to set up a meeting with Dr. Roberto.
