Reference excerpt

Hannele Ruohola-Baker (born December 10, 1959) is a Finnish biochemist. She is a professor of biochemistry and associate director of the Institute for Stem Cell and Regenerative Medicine at the University of Washington in Seattle, Washington. Her research focuses on the molecular biology of stem cells and on the use of Drosophila (fruit flies) as model organisms for human diseases.

Early life and education Ruohola-Baker was born in the small village of Kullaa, Finland, in 1959. She received her bachelor's and master's degree from the University of Helsinki and received her Ph.D. in cell biology from Yale University in 1989, studying cellular transport and advised by Susan Ferro-Novick. She then moved to a visiting fellowship at the Ludwig Institute for Cancer Research at the Karolinska Institute in Stockholm and subsequently to a postdoctoral fellowship at the University of California, San Francisco with Yuh Nung Jan and Lily Jan.

Academic career Ruohola-Baker began her faculty career at the University of Washington in 1993 and became a full professor in 2004. She held a Pew Scholars grant from 1996-2000.

Research Ruohola-Baker's research focuses on stem cells and the molecular requirements for differentiation, with particular interest in the role of microRNA and in the relationship between metabolism and epigenetic changes in different types of stem cells. The research group also has a long-standing interest in studying the Notch and S1P signaling pathway using Drosophila as models of human diseases, particularly Duchenne muscular dystrophy and cancer.

Personal life Ruohola-Baker is married to fellow UW biochemist David Baker, who won the 2024 Nobel Prize in Chemistry.

Worked examples

Example 1 — a first encounter with Hannele Ruohola-Baker

Start with the simplest possible case. Write down what Hannele Ruohola-Baker claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Hannele Ruohola-Baker 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 Hannele Ruohola-Baker 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 Hannele Ruohola-Baker

In research: Hannele Ruohola-Baker appears in astronomy 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 Hannele Ruohola-Baker 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: Hannele Ruohola-Baker is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1959 births, 21st-century American women, American women academics, so understanding it makes those chapters shorter.
In everyday life: Look for Hannele Ruohola-Baker 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.
