Cornell PIN has one of the largest networks of alumni of any international nutrition program.  Over 160 doctoral degrees and 109 master’s level degrees have been awarded over the last four decades and Cornell PIN alumni work all over the globe. Members of our network are continuing to contribute to better nutrition everywhere, working with international agencies, national governments and bilateral donors, educational and research institutions, non–governmental organizations, the private sector, and as practitioners and consultants in a diverse array of programs and initiatives. Our greatest impacts are through the endeavors of these talented people.

I encourage students interested in both chemistry and healthy food to consider nutritional sciences as a career.

portrait of Dr. Acuin

Cecilia S. Acuin, PhD '13: Chief, Nutrition Assessment and Monitoring Division, Food and Nutrition Research Institute, Department of Science & Technology, Philippines

Advisors: Dr. Gretel Pelto, Dr. Jean-Pierre Habicht

Current Focus: I am responsible for the conduct of the Philippine National Nutrition Surveys, and oversee nutrition research projects of three Sections: the Nutritional Assessment Section, the Nutritional Statistics and Informatics Section, and the Nutritional Interventions, Evaluation and Policy Section. My research interests are in the areas of maternal and child health and nutrition, health and nutrition systems and operations research, and risk factors of non-communicable diseases. My advocacies include equity in health and nutrition, and the cause of persons with disabilities, particularly those with autism and other developmental disorders.

Cornell PIN experiences: The diversity of people and experiences I was exposed to made me appreciate the many different ways that nutritional sciences may be used. While we (researchers) would like to see evidence as the basis for decisions, the reality is that resources and contexts dictate how such evidence is ultimately applied.

Suggestions for current graduate students: Take advantage of every opportunity to meet new people and explore new environments. Talk to the faculty, even those outside PIN and outside DNS, and learn not just from their lectures but, more importantly, also from their experiences.

I also work in Nepal and Uganda, two SUN countries, on a case study of the roll-out of national multi-sectoral nutrition plans.

Cornell PIN experiences: Graduate study in PIN taught me critical thinking to conceptualize and implement research, and analytical skills to present and critique research findings. PIN was one of few programs that trained students to develop a policy perspective to keep our specific work relevant in the larger context.

Suggestions for current graduate students: Explore and take opportunities that bring new experiences and exposure to new challenges. Be hands-on and organized.

portrait of Dr. Greiner

Ted Greiner, MS '77, PhD '83, retired

Advisor(s): Michael Latham

Current Focus: Editor-in-chief of the journal of the World Public Health Nutrition Association ( called World Nutrition, which would be delighted to receive manuscripts from Cornell students and alumni. The journal is funded through membership fees and is free to both readers and authors.

Cornell PIN Experience: When I first set foot on the Cornell campus, I literally danced under the trees. I knew I had finally found my calling in nutrition. When I first started (January 1974), I made appointments with 18 nutrition professors around campus to learn what they were doing and if the would be interested in a new grad student working with them. I had been a teaching or research assistant multiple times by the time I left (July 1983). The first was working on a literature review for Professor Jere Rivers on the impact of hard vs. soft water on heart disease. I got hooked on international nutrition in Professor Michael Latham's class because of his in-depth knowledge of what it's like in the field and his love of Africa and its people. He remained a mentor and friend until his passing in 2011. I worked closely with him on three Cornell International Nutrition Monographs and several papers, the last in 2010, The Great Vitamin A Fiasco.

Rebecca Heidkamp, PhD '11, Assistant Scientist, Institute for International Programs & Center for Human Nutrition, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD,USA

Advisors: Rebecca Stoltzfus, Jean-Pierre Habicht, Kathleen Rasmussen

Current focus: I lead a multi-country project in Africa focused on developing technical methods and building government capacity for high-level evaluation of maternal newborn child health and nutrition policies and programs. I’m also involved in several smaller projects related to measuring and modeling nutrition programs at scale.

Cornell PIN experiences: I still credit NS7030 for the communications and critical thinking skills that underlie much of my current work. The strong relationships I developed with my DNS mentors and peers continue to this day. I’m currently on a WHO committee that involves three fellow DNS alumni and am working on a small grant with another DNS peer who works at a different institution.  Not to mention the wonderful global reunions I’ve had – by chance or design – with DNS friends and faculty in Dar es Salaam, Nairobi, Quebec, Switzerland, India and beyond!

portrait of Dr. Herforth

Anna Herforth, PhD '10, Independent Consultant and Researcher, New Haven, CT, USA

Advisor: Per Pinstrup Andersen  

Current focus: My work focuses on linkages between agriculture, food security, and nutrition around the world.

Cornell PIN experiences: Launching the Food Agriculture and Nutrition Group (FANG) during graduate school was practice in connecting people across disciplines professionally. The FANG model was scaled up in partnership with Emily Levitt Ruppert, who founded the Ag2Nut Community of Practice. Emily and I saw this group from our first meetings of five people around a conference table in DC to now, a vibrant online community of over 2000 people in over 90 countries (and counting). This group created a unified statement of Key Recommendations for Improving Nutrition through Agriculture and Food Systems which has been adopted by the UN FAO, USAID, and used by many other organizations. 

Suggestions for current graduate students: Satisfying work is only partly about the subject matter, and mostly about how you spend your time every day. Notice how you feel when you are doing what you do. Turn toward experiences and collaborations that bring you energy and peace. These essential skills of noticing and responding are self-taught; graduate school is a great time to practice them.

Andrew Jones, PhD '11, Assistant Professor, Department of Nutritional Sciences, School of Public Health, University of Michigan, Ann Arbor, MI, USA  

Advisor: Per Pinstrup-Andersen

Current focus: My research program is focused on understanding the influence of agriculture and food systems on the diets and nutritional status of women and children in low- and middle-income countries. Specifically, I examine: 1) biophysical, sociocultural and microbial mechanisms via which smallholder agricultural production systems influence maternal and child nutrition; and 2) the role of food systems changes associated with the “nutrition transition” in potentiating risk of concurrent undernutrition and obesity at community-, household- and individual-scales.

Cornell PIN experiences: The faculty members in PIN and throughout DNS are not only world-class researchers, but also dedicate enormous energies to supporting students. The education I received at Cornell provided me the foundational skills and knowledge to launch and lead an independent research program in international nutrition. But perhaps more importantly, I continually draw from the example set by PIN and DNS faculty in ensuring that my priorities are centered on student mentorship, and shared learning through collaboration.

jackie kungu

Jacqueline Kung'u, PhD '08; Regional Adviser Research and Evaluation (Africa Region), Nutrition International

Advisor: Rebecca Stoltzfus

Current focus: Nutrition International’s work focuses on strengthening health systems in Africa through evidence–based programming. My role involves: contributing to the technical quality of the MI’s programs and research in Africa; guiding the utilization of evidence as a basis for NI’s programs, and participating in the generation and dissemination of new evidence related to diverse health and nutrition programs among country level stakeholders, presentations in national, regional and global meetings and publications in scientific peer reviewed journals.

Cornell PIN experience: At Cornell I learned that my opinion counts and I should never be afraid to share it. There were various opportunities for reflective and independent thinking throughout the program and I actually remember thinking how much others valued my opinions. I also remember that I had a wonderful mentorship relationship with my advisor and that despite being a very accomplished researcher, she still valued my input in research.

Suggestions for current graduate students: Have clear career goals that you are committed to but be flexible enough to see opportunities around you. Always invest in others by mentoring and empowering upcoming researchers. It's time consuming but very rewarding! 

portrait of Dr. Leroy

Jef Leroy, PhD '05; Senior Research Fellow, Poverty, Health, and Nutrition Division,International Food Policy Research Institute (IFPRI), Washington, D.C., USA

Advisor: Jean-Pierre Habicht

Current focus: Jef Leroy, a Belgian citizen, is a Senior Research Fellow in IFPRI’s Poverty, Health, and Nutrition Division. He studies the impact of two large-scale integrated food and nutrition programs in Burundi and Guatemala on maternal and child nutrition and health. He is also involved in research on the impact of aflatoxin on child linear growth in Kenya and Mexico and studies the measurement of linear growth retardation. Before joining IFPRI in July 2009, he was a research associate at the Center for Evaluation Research and Surveys at Mexico’s National Institute of Public Health in Mexico. In Mexico, he worked on the impact evaluation of large scale programs, including the impact of Mexico’s urban and rural Oportunidades programs on child nutrition and health, and the impact of the Programa de Apoyo Alimentario (a cash and in-kind transfer program) on household food consumption and women's weight. He has also conducted research on child mortality.

Cornell PIN experience: The “vitamin A course” was remarkable. The course started with molecular structure of β-carotene and retinol, and ended with vitamin A-related programs and policies. The insights from this course are extremely relevant for impact evaluation: it serves as a reminder not only to remember the underlying biology of the problems we are trying to address, but also reminds us to focus on understanding the (behavioral) pathways of impact.

Advisors: Jere Haas, Jean-Pierre Habicht

Current focus: My role as Dean involves strategic oversight of teaching and learning development and academic administration in the faculty.

My teaching and research is in the field of public health nutrition, with a core interest in using research to strengthen nutrition policy & programming – particularly in relation to food and nutrition security, food systems, micronutrient malnutrition, and non-communicable disease prevention.  My work has involved projects throughout the Asia-Pacific region, with the principal areas being Australia, Indonesia and Papua New Guinea.

Cornell PIN experiences: For me, the two major features of the International Nutrition program at Cornell were:

  1. exposure to a range of great teachers and researchers in international nutrition as a cross-disciplinary field, that provided a perspective and way of approaching nutrition issues that has continued to be valuable over time; and
  2. most significantly, an international cohort of colleagues also studying for the PhD that provided an incredibly supportive environment, set a challenging standard for learning and research, and an enriching network of colleagues since graduation.

Victoria Quinn, MS '82; Helen Keller International’s Senior Vice President for Programs, Washington DC

Advisor(s): Jere Haas

Background: After getting my Masters in 1982, I moved to Africa for 16 years (Kenya, Malawi and Ghana). During this time I worked close to 9 years as the Regional Program Coordinator of the Cornell Food and Nutrition Policy Program and was seconded to UNICEF’s regional office for eastern and southern Africa in Nairobi.

I later received my PhD from Wageningen University in the Netherlands in 1994.  My thesis was titled “Nutrition and National Development:  An Evaluation of Nutrition Planning in Malawi from 1936 to 1990” (published by Wageningen Agriculture University Press, The Hague, The Netherlands). In 1998 I returned to the United States and settled with my husband and son in Washington DC where I served for over 8 years as the Senior Technical Manager overseeing the flagship programs for the USAID-funded LINKAGES Infant Feeding project.

Current Focus: Since 2006 I’ve been serving as Helen Keller International’s Senior Vice President for Programs based in their Washington DC office. In this capacity I oversee HKI’s programs in nutrition, eye health and neglected tropical diseases across the regions of Sub-Saharan Africa and Asia Pacific. My specific areas of expertise include food security and nutrition policy and surveillance, infant and young child feeding (including aspects of food marketing), micronutrients, women’s nutrition as well as nutrition sensitive programming especially within the agricultural sector. Most recently I co-edited and authored the 3rd edition of the Oxford University Press textbook “Nutrition for Developing Countries” with Savage-King, Burgess and Osei which was published in late 2015 and later awarded the distinction of  “Highly Commended” in the Public Health category under the 2016 British Medical Association Book Awards:
