Reference excerpt

Teresa Kaye Woodruff is an American university administrator and medical researcher in human reproduction and oncology, with a focus on ovarian biology, endocrinology, and women's health. She is President Emerita of Michigan State University, having served as interim president from 2022 to 2024. Woodruff initially joined Michigan State University as the Provost and Executive Vice President for Academic Affairs in 2020. In 2025, she was a recipient of the National Medal of Science, the first person from Michigan State University to receive the honor. Woodruff was previously Dean of the Graduate School and Professor in the McCormick School of Engineering at Northwestern University. She served as the Thomas J. Watkins Memorial Professor and Vice Chair for Research and Chief of the Division of Reproductive Science in Medicine in the Department of Obstetrics and Gynecology at the Feinberg School of Medicine at Northwestern University in Chicago, Illinois. Woodruff is credited with coining the term oncofertility and founded the Oncofertility Consortium at Northwestern Memorial Hospital. She is also founder and chief of the Division of Fertility Preservation and founder and director of the Women's Health Research Institute at Northwestern University. In 2026, she was elected to the American Philosophical Society and the Royal Society.

Education Woodruff graduated with a Bachelor of Science degree in Zoology and Chemistry from the Olivet Nazarene University in 1985. She was awarded the "O" Award in 2016, presented "to honor alumni who exhibit the characteristics and ideals of their alma mater." She completed her graduate study at Northwestern University, receiving a Ph.D. in Molecular Biology and Cell Biology in 1989. She was recognized by Northwestern with their highest honor for an alum, the Northwestern Alumni Association Merit Award in 2012. She is the recipient of two honorary degrees (Honorary Scientiae Doctoris, i.e., D.Sc.), nationally from Bates College in Lewiston Maine (2010) and internationally from University of Birmingham, School of Medicine in Birmingham, UK (2016).

Career

Ovarian biology research In 1986, as a graduate student in the laboratory of Kelly Mayo at Northwestern University, Woodruff cloned the protein subunits that form the peptide hormones inhibin and activin. This work was recognized in 2000 by the Endocrine Society Weitzman Award, which is presented to "an exceptionally promising young clinical or basic investigator who has not reached the age of 50." After completing her doctorate in 1989, Woodruff completed a postdoctoral fellowship at Genentech, Inc in South San Francisco, CA, where she contributed to the development of inhibin and activin assays, which are used today for the diagnosis of Down syndrome and to measure the ovarian reserve. She is named as inventor on five patents based on her work at Genentech. Woodruff also continued her research into the physiology of inhibin and activin in pituitary and ovarian function in rodent and the effects of recombinant human inhibin and activin in primates. Woodruff returned to Northwestern University as a faculty member in 1995 to study inhibin and activin actions and interactions within the pituitary-gonadal axis, characterizing the regulation of subunit assembly and ligand processing in the ovary, the ligands' role in paracrine regulation of folliculogenesis, and their signal transduction pathways in the regulation of follicle-stimulating hormone (FSH). In collaboration with Theodore Jardetzky, she solved the crystal structures of activin with its receptor and with its bioneutralizing binding protein follistatin. In 2015, her lab used in silico methods to design small molecule activin antagonists based on the structure of activin bound to its receptor. Using single-cell elemental analytical methods at the Argonne National Laboratory in collaboration with inorganic chemist Tom O'Halloran, Woodruff discovered a role of zinc in the regulation of oocyte maturation and at the moment of fertilization. Using single-cell x-ray fluorescence, Woodruff and O'Halloran described the phenomenon of the "zinc spark," an event during which 10 billion zinc ions are lost from the egg. The discovery of the zinc spark was named as one of Discover magazine's top 100 stories of 2016.

Worked examples

Example 1 — a first encounter with Teresa Woodruff

Start with the simplest possible case. Write down what Teresa Woodruff claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Teresa Woodruff before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Teresa Woodruff ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Teresa Woodruff

In research: Teresa Woodruff appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Teresa Woodruff in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Teresa Woodruff is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century American scientists, 20th-century American women scientists, 21st-century American scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Teresa Woodruff outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
