Key takeaways

Jan E. Leach belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Jan E. Leach to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jan E. Leach from memory before moving on to harder problems.

Reference excerpt

Jan Elnor Leach (born 1953) is an American plant pathologist. She is known for her research of the molecular biology of plant pathogens, particularly those affecting rice plants. She was the co-editor of the Annual Review of Phytopathology from 2015-2022 and is a fellow of the American Association for the Advancement of Science and a member of the National Academy of Sciences.

Early life and education Jan Elnor Leach was born in 1952 or 1953 in Lincoln, Nebraska to parents Jessamine and Lewis Leach. After attending Dordt University, a small college in Iowa, for two years, she transferred to the University of Nebraska–Lincoln, graduating in 1975 with a bachelor's degree in microbiology. She stayed at the University of Nebraska–Lincoln for her master's in microbiology, graduating in 1977. She attended the University of Wisconsin–Madison for her PhD in plant pathology, graduating in 1981.

Career After graduating with her PhD, she was a post-doctoral researcher from 1981 to 1984 at the East Malling Research Station in the United Kingdom. She then worked at Kansas State University as an assistant professor, becoming an associate professor in 1990 and a full professor in 1995. At KSU, she researched the bacteria Xanthomonas oryzae pv. oryzae, which is a bacterial blight of rice In 1997, she accepted a position at the International Rice Research Institute as a scientist and plant pathologist. She joined the faculty of Colorado State University in 2004 and she is a professor in the Department of Agricultural Biology in the Colorado State University College of Agricultural Sciences. She was made a University Distinguished Professor in 2007, and the Research Associate Dean of the College of Agricultural Sciences in 2015. She has served as the editor of the journal Molecular Plant-Microbe Interactions; she has been the co-editor of the Annual Review of Phytopathology with Steven E. Lindow from 2015 to 2022.

Awards and honors In 1996, she was made a Distinguished Graduate Faculty Member at Kansas State; in 1998, she was named a University Distinguished Professor. She was elected as a fellow of the American Phytopathological Society in 1998, the American Academy of Microbiology in 2000, and the American Association for the Advancement of Science in 2002. She was the president of the International Society for Molecular Plant-Microbe Interactions from 1999 to 2001. In 2019, she won the Agropolis Fondation Louis Malassis International Scientific Prize for Agriculture and Food in the "Distinguished Scientist" category. In 2021, she was elected member of the U. S. National Academy of Sciences.

Personal life She is married to Ned Tisserat, also a plant pathologist.

Worked examples

Example 1 — a first encounter with Jan E. Leach

Start with the simplest possible case. Write down what Jan E. Leach 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 Jan E. Leach 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 Jan E. Leach 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 Jan E. Leach

In research: Jan E. Leach 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 Jan E. Leach 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: Jan E. Leach is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s births, 21st-century American academics, 21st-century American women academics, so understanding it makes those chapters shorter.
In everyday life: Look for Jan E. Leach 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.
