Ann E. Hagerman is an American biochemist and distinguished academic, widely recognized for her extensive research on the chemistry and biology of tannins and other plant polyphenols. She is a Distinguished Professor of Biochemistry at Miami University in Oxford, Ohio.
Career and Research: Hagerman's primary research contributions revolve around understanding the complex interactions of tannins—a class of astringent, polyphenolic biomolecules—with proteins and other biological macromolecules. Her work has significantly advanced the fields of plant biochemistry, nutritional biochemistry, and chemical ecology. Key areas of her research include:
- Tannin-Protein Interactions: Investigating the mechanisms by which tannins bind to and precipitate proteins, affecting their function, digestibility, and palatability. This research has critical implications for animal nutrition and the food industry.
- Plant Defense Mechanisms: Exploring the role of tannins as a defense against herbivores and pathogens in various plant species.
- Biological Effects of Tannins: Studying the impact of dietary tannins on digestion, nutrient absorption, and animal physiology, including their potential anti-nutritional and medicinal properties.
- Analytical Chemistry of Polyphenols: Developing and refining methods for the extraction, identification, and quantification of tannins and other plant secondary metabolites.
Her work has been instrumental in elucidating how tannins contribute to the astringent taste in many foods and beverages, and their broader ecological significance in plant-animal interactions.
Academic Affiliations: Ann E. Hagerman has dedicated a substantial part of her academic career to Miami University (Ohio), where she has achieved the rank of Distinguished Professor of Biochemistry.
Impact and Recognition: Professor Hagerman is a highly cited researcher and is considered a leading authority in tannin chemistry and its biological implications.
