Katherine H. Freeman

Katherine H. Freeman is a biology 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 Katherine H. Freeman rather than just read about it. In short: Katherine Haines Freeman is the Evan Pugh University Professor of Geosciences at Pennsylvania State University and a co-editor of the peer-reviewed scientific journal, Annual Review of Earth and Planetary Sciences. Her research interests are organic geochemistry, isotopic biogeochemistry, paleoclimate and astrobiology.

Key takeaways

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

Reference excerpt

Katherine Haines Freeman is the Evan Pugh University Professor of Geosciences at Pennsylvania State University and a co-editor of the peer-reviewed scientific journal, Annual Review of Earth and Planetary Sciences. Her research interests are organic geochemistry, isotopic biogeochemistry, paleoclimate and astrobiology.

Academic background In 1984 Wellesley College awarded Freeman her B.A. in geology and classical civilization. At Indiana University, Bloomington she obtained her M.S. (1989) and Ph.D. (1991) in geology under the direction of John M. Hayes. Freeman then did a postdoc at the Skidaway Institute of Oceanography (Savannah, Georgia) in 1990-91, and subsequently joined Pennsylvania State University in 1991. Freeman was appointed a Distinguished Professor in 2015 and later an Evan Pugh University Professor in 2016 by Penn State. An Evan Pugh University professorship is the highest honor that Pennsylvania State University can bestowed on a member of its faculty.

Awards Freeman is a fellow of the American Geophysical Union (2013), The Geochemical Society and European Association of Geochemistry (2011), American Academy of Microbiology (2011), John Simon Guggenheim Memorial Foundation (2010), Geological Society of America (2007), and Canadian Institute for Advanced Research (2001). She was awarded the Heinz A. Lowenstam Science Innovation Award in 2012 from the European Association of Geochemistry. Her paper titled "Water, plants, and early human habitats in eastern Africa" earned the 2012 Cozzarelli Prize for Physical and Mathematical Sciences. She was elected to membership in the National Academy of Sciences in 2013. She received the 2017 Alfred Treibs Award from the Geochemical Society for her contributions to organic geochemistry. Freeman was also awarded the Nemmers Prize in Earth Sciences in 2020 for her significant contributions to the field of stable isotope geochemistry.

Worked examples

Example 1 — a first encounter with Katherine H. Freeman

Start with the simplest possible case. Write down what Katherine H. Freeman 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 Katherine H. Freeman 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 Katherine H. Freeman 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 Katherine H. Freeman

In research: Katherine H. Freeman 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 Katherine H. Freeman 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: Katherine H. Freeman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American earth scientists, 21st-century American women biologists, Academic journal editors, so understanding it makes those chapters shorter.
In everyday life: Look for Katherine H. Freeman 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.
