Three alumni honored with Alumni Impact Awards

Three Department of Food Science and Human Nutrition alumni recently were presented the 2017 Alumni Impact Award.

Celeste Clark ('77, nutrition) and Susan Roberts ('73, dietetics) were honored during the FSHN Alumni Awards Banquet Oct. 26, at the Hansen Agriculture Student Learning Center. The third winner, Tunyawat Kasemsuwan ('91 & '95, food science and technology), could not make it to the banquet, so a special ceremony took place Nov. 10, during which he gave a brief seminar and then was presented his award.

The FSHN Alumni Impact Award recognizes individuals who have excelled and made an impact in their professions or community, and maintain the spirit of Iowa State University. This is the seventh year alumni have been honored with this award.

This year's winners are:

Celeste Clark, '77 MS nutrition

Celeste Clark holds a bachelor of science degree in food and nutrition from Southern University. She came to Iowa State University to pursue a master of science degree in nutrition, which she earned in 1977. Clark later went on to receive her doctoral degree in food science and human nutrition from Michigan State University in 2004.

Clark has more than 30 years of corporate experience and is an internationally known and recognized expert in the field of food and health policy. She held several positions with Kellogg Company over the years, including manager of nutrition communications, director of food service marketing and sales, senior vice president of global public policy and external affairs, and chief sustainability officer. In addition, she serves on a number of boards, including Mead Johnson Nutrition, W.K. Kellogg Foundation and Diamond Foods, Inc.

In his nomination letter, Kris Spence wrote the following about Clark, “Dr. Celeste Clark demonstrates a passion for serving others and leaving the world a better place than they found it, both through her professional career accomplishments and her private philanthropy and mentoring. At Kellogg, she always provided me with great advice and support, and she was an exemplary role model for doing what is right.”

Tunyawat Kasemsuwan earned his bachelor of science degree in biotechnology from Mahidol University in 1987. He continued his education at Iowa State University, receiving his master’s degree in food science and technology in 1991, followed by his doctoral degree in 1995, all under the direction of Dr. Jay-Lin Jane.

Kasemsuwan currently serves as the director of Global Innovation at Thai Union, one of the world’s largest seafood processors. In this position, he works to develop global innovation strategy and build new infrastructure to support company strategic growth.

Prior to joining Thai Union, Tunyawat held dual positions as a senior director of technology for Asia Pacific and global clinic/infant nutrition for Ingredion. He was also an inaugural director for research and development for Asia, Europe and Latin America regions of Mead Johnson.

In her letter of support for Tunyawat’s nomination for the Alumni Impact Award, Dr. Jane wrote, “Dr. Kasemsuwan has shown drive and determination to get jobs done since he was a graduate student. He is highly creative and has a demonstrated leadership. These characteristics assured his outstanding career achievements. In addition to all those unique abilities, Dr. Kasemsuwan also has a very pleasant personality. He was well liked by professors, staff and colleagues.”

Susan Roberts, '73 BS dietetics

Susan Roberts holds a bachelor of science degree in dietetics, which she earned at Iowa State University in 1973. Following the completion of her dietetic internship, Roberts went on to earn her master’s degree in preventive medicine and environmental health from the University of Iowa.

Presently, Roberts is the vice president for Partnership for a Healthier America.

She’s also the president of Sue Roberts Health Concepts, a health and wellness consulting firm she started that empowers and supports individuals in their health journeys. It was thru working with this firm that HyVee decided to begin hiring registered dietitians. The grocery chain now employs more than 250 registered dietitians throughout the Midwest, some of which are Iowa State graduates.

In a nomination letter, Dr. Ruth Litchfield wrote the following about Roberts: “She is very deserving of the Alumni Impact Award from the Department of Food Science and Human Nutrition.
