Reference excerpt

Shawn D. Domagal-Goldman is a research space scientist at NASA Goddard Space Flight Center, who specializes in exoplanets, Archean geochemistry, planetary atmospheres, and astrobiology.

Education and career Domagal-Goldman has a master's degree in Earth Sciences from the University of Rochester and a PhD in Geosciences and Astrobiology from the Pennsylvania State University. Domagal-Goldman helped organize FameLab events in the US. He also talks about NASA science in public forums, such as AwesomeCon. He is a recipient of the 2019 Presidential Early Career Award for Scientists and Engineers.

Research For his research into "the early Earth and other terrestrial planets, he works on utilizing isotopic trends as proxies for atmospheric processes and elemental cycling", which "includes work on the fundamental controls on iron isotope fractionation and on global controls on mass-independent Sulfur isotope fractionation (S-MIF)". For extrasolar planets, he works on "spectroscopy-based characterization techniques" that inform scientists about "a planet's surface climate, habitability, and ecosystems". His research experience includes:

July 2007–present, Atmospheric Modeler, NASA Astrobiology Institute · Virtual Planetary Laboratory July 2010–July 2012, NASA Astrobiology Management Postdoctoral Fellow, Oak Ridge Associated Universities, NASA Headquarters July 2008–July 2010, Research Associate, University of Washington Seattle · Department of Astronomy Research Associate at Penn State

Personal life Domagal-Goldman has a daughter, her name is Maya.

Worked examples

Example 1 — a first encounter with Shawn Domagal-Goldman

Start with the simplest possible case. Write down what Shawn Domagal-Goldman 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 Shawn Domagal-Goldman 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 Shawn Domagal-Goldman 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 Shawn Domagal-Goldman

In research: Shawn Domagal-Goldman 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 Shawn Domagal-Goldman 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: Shawn Domagal-Goldman is common in secondary-school and first-year university syllabi. It links to neighbouring topics American scientists, Living people, Recipients of the Presidential Early Career Award for Scientists and Engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Shawn Domagal-Goldman 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.
