Maria Harrison

Maria Harrison is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Maria Harrison rather than just read about it. In short: Maria J. Harrison is William H.

Key takeaways

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

Reference excerpt

Maria J. Harrison is William H. Crocker Scientist professor at the Boyce Thompson Institute for Plant Science, and adjunct professor in the School of Integrative Plant Science at Cornell University.

Education She received her PhD in biochemistry from the University of Manchester in 1987 for research investigating gene expression in tomato seeds supervised by T.A. Brown.

Career and research Harrison's lab, including post-doctoral, graduate, undergraduate, and intern students, utilizes a combination of molecular, cell biology, genetic, and genomic techniques to investigate the developmental mechanisms underlying the symbiosis and phosphate transfer between arbuscular mycorrhizal fungi (AM fungi; AMF) (including Glomus versiforme, Glomus intraradices, and Gigaspora gigantea) and the roots of model legume Medicago truncatula. Among Harrison's most notable findings are that plants use hormone signaling to regulate AM fungi symbiosis and that phosphate transport is critical to the maintenance of this symbiosis. These discoveries have allowed the field of fungal-plant interactions to pursue new research questions including future manipulation of phosphate acquisition in valuable crop species.

Honors and awards She was elected a member of the National Academy of Sciences in April 2019 and a Fellow of the Royal Society (FRS) in 2024. Other awards and honours include:

Cornell University College of Agriculture and Life Sciences Faculty Excellence in Undergraduate Research Mentoring Award (2015) The Dennis R. Hoagland Award (2015) American Academy of Microbiology (AAM) Fellow (2013) American Association for the Advancement of Science (AAAS) Fellow (2012) William H. Crocker Scientist (2011)

Worked examples

Example 1 — a first encounter with Maria Harrison

Start with the simplest possible case. Write down what Maria Harrison 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 Maria Harrison 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 Maria Harrison 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 Maria Harrison

In research: Maria Harrison 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 Maria Harrison 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: Maria Harrison is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American women, Alumni of the University of Manchester, American botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Maria Harrison 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.
