Key takeaways

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

Reference excerpt

Laura Grace DeMarco is an American mathematician who is a professor of mathematics at Harvard University, whose research concerns dynamical systems and complex analysis.

Career DeMarco received her Ph.D. from Harvard University in 2002 under the supervision of Curtis T. McMullen. She held an NSF Postdoctoral Fellowship and was an L. E. Dickson Instructor at the University of Chicago from September 2002 to August 2005. She was also an assistant professor at the University of Chicago, and then she moved to the University of Illinois at Chicago, where she was tenured and promoted to professor. She moved to Northwestern University in 2014, and was promoted to Henry S. Noyes Professor of Mathematics in 2019, before she moved to Harvard University in 2020. She has been appointed the Hollis Professor of Mathematicks and Natural Philosophy as of 2026 DeMarco is an organizer of GROW (Graduate Research Opportunities for Women) undergraduate conference.

Awards and honors In 2013, DeMarco became a fellow of the American Mathematical Society in the inaugural class of fellows. In 2017, she received the AMS Ruth Lyttle Satter Prize in Mathematics in Mathematics for her contributions to complex dynamics, potential theory, and the emerging field of arithmetic dynamics. In 2020, DeMarco was elected a member of the National Academy of Sciences. She was an invited speaker at the 2018 International Congress of Mathematicians, speaking in the section on Dynamical Systems and Ordinary Differential Equations. She is the 2023 AWM-AMS Emmy Noether Lecturer in recognition of her "fundamental and influential contributions to complex dynamics, arithmetic dynamics, and arithmetic geometry." Her work with Holly Krieger and Hexi Ye, "Uniform Manin–Mumford for a family of genus 2 curves", published in the Annals of Mathematics, won the 2020 Alexanderson Award of the American Institute of Mathematics.

Research DeMarco's research involves algebraic, arithmetic and complex dynamics with an emphasis on their interactions with each other. She has studied dynamically meaningful compactifications of the moduli space of rational maps on P 1 . {\displaystyle \mathbb {P} ^{1}.} In joint work with Curtis McMullen, she showed how simplicial metrized trees can be used to compactify the moduli space of polynomials. Together with Xander Faber, DeMarco has studied degenerations of complex dynamical systems from the viewpoint of Berkovich spaces. With Matthew Baker, DeMarco pioneered the study of unlikely intersections in arithmetic dynamics and formulated the dynamical André-Oort conjecture. Together with Holly Krieger and Hexi Ye, DeMarco proved the first instances of the uniform dynamical Manin-Mumford conjecture for Lattès maps and for quadratic unicritical polynomials. In collaboration with Niki Myrto Mavraki, DeMarco studied the notion of non-degeneracy for polarized dynamical systems and its relation to stability. Later with Niki Myrto Mavraki and Hexi Ye, DeMarco proved a uniform version of the dynamical André-Oort conjecture.

Worked examples

Example 1 — a first encounter with Laura DeMarco

Start with the simplest possible case. Write down what Laura DeMarco 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 Laura DeMarco 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 Laura DeMarco 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 Laura DeMarco

In research: Laura DeMarco 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 Laura DeMarco 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: Laura DeMarco is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American mathematicians, 21st-century American women mathematicians, Dynamical systems theorists, so understanding it makes those chapters shorter.
In everyday life: Look for Laura DeMarco 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.
