Reference excerpt

Sonya Dyhrman is an earth and environmental sciences professor who studies the physiology of phytoplankton and their role within marine ecosystems. She is also a fellow of the American Academy of Microbiology.

Education and career Dyrhman grew up in Washington where she spent days clamming on Puget Sound and started scuba diving before she could drive. She went to Dartmouth College and received her B.A. in 1994. She then earned her Ph.D. from Scripps Institution of Oceanography, University of California, San Diego in 1999. Following her Ph.D., she joined Woods Hole Oceanographic Institution as postdoc and transitioned onto the scientific staff in 2002. In 2014, she moved to Columbia University, Lamont–Doherty Earth Observatory (LDEO) where she is a professor in earth and environmental sciences.

Research Dyhrman uses molecular tools to examine phytoplankton in marine systems, with a focus on their ecosystem structure and biogeochemical impact. Her Ph.D. research examined the role of phosphate stress on phytoplankton where she identified proteins found in dinoflagellates grown under phosphate-limited conditions and then applied this tool to assess phosphate-stress conditions in the field. She has examined variability in how phytoplankton consume and produce different forms of phosphorus including dissolved organic phosphorus, polyphosphate, and phosphonates. Dyhrman has also looked at cell-specific phosphorus stress using Trichodesmium as a model cyanobacteria, and specifically examined how use Trichodesmium use phosphonate in the ocean. A portion of her research interests include investigations into diatoms, cyanobacteria, and harmful algal organisms.

Worked examples

Example 1 — a first encounter with Sonya Dyhrman

Start with the simplest possible case. Write down what Sonya Dyhrman 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 Sonya Dyhrman 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 Sonya Dyhrman 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 Sonya Dyhrman

In research: Sonya Dyhrman 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 Sonya Dyhrman 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: Sonya Dyhrman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1972 births, American oceanographers, Dartmouth College alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Sonya Dyhrman 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.
