Faculty Spotlight

Reina Engle-Stone

Dr. Reina Engle-Stone’s office has a colorful map of the world and some of the ephemera around her desk includes a Ziploc bag of aromatic bouillon cubes from Cameroon, in West Africa, where she’s done a lot of her research. 

Her focus is micronutrients. Specifically, assessing whether large populations are getting enough of them (or sometimes too much), and then making recommendations about nutritional fortification.

Designated Emphasis

PICN Graduate Students

A formal Designated Emphasis in International and Community Nutrition is available to doctoral students in participating graduate programs.

Successful completion of the requirements for the Designated Emphasis will be recognized on the student's diploma at the time of awarding the doctoral degree. For example, students of the Graduate Group in Nutritional Biology will receive a "Ph.D. in Nutritional Biology with emphasis in International and Community Nutrition".

Kathryn G. Dewey

Kathryn G. Dewey, Ph.D., PICN Director

For nearly 35 years, UC Davis distinguished nutrition professor and PICN Director Kathryn Dewey has been a leader in research on maternal and child nutrition, infant feeding, and assessment of child growth. Her work has contributed key evidence prompting changes in global policies and guidelines.


The UC Davis Program in International and Community Nutrition (PICN) coordinates research and training activities concerning human nutrition problems of low-income countries, and of ethnic minorities and disadvantaged groups in the United States.  PICN also offers a Designated Emphasis program for doctoral students in participating graduate programs.

The specific objectives of the PICN are:

  • To conduct basic and applied research on issues of human nutrition relevant to low-income and disadvantaged populations.
  • To plan and manage the educational curriculum leading to a Designated Emphasis (minor) in International and Community Nutrition for doctoral students of the participating graduate programs, and to coordinate training activities for other graduate students and post-doctoral fellows.
  • To provide technical assistance to national governments and international agencies concerned with food and nutrition policies.
  • To foster collaborative exchanges of students and faculty between UC Davis and research and training institutions abroad.

Invest in the Future

Malnutrition is a leading cause of death in young children throughout the world. For infants and children under the age of two, the consequences of malnutrition are particularly severe, often irreversible. Improved nutrition for mothers and young children is one of the best investments we can make to achieve lasting progress in global health and development. 

Join us in making a difference in the fight against malnutrition by making a donation to our fund to establish an endowed chair in maternal and infant nutrition in the Department of Nutrition.



PICN Seminars are now available online.
