Jinyoung Park (mathematician)

Jinyoung Park (mathematician) is a mathematics 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 Jinyoung Park (mathematician) rather than just read about it. In short: Jinyoung Park (Korean: 박진영; born 1982) is a South Korean mathematician at the Courant Institute of Mathematical Sciences at New York University working in combinatorics and graph theory. She and Huy Tuan Pham proved the Kahn–Kalai conjecture on estimating the positions of phase transitions in statistical mechanics and random graph theory.

Key takeaways

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

Reference excerpt

Jinyoung Park (Korean: 박진영; born 1982) is a South Korean mathematician at the Courant Institute of Mathematical Sciences at New York University working in combinatorics and graph theory. She and Huy Tuan Pham proved the Kahn–Kalai conjecture on estimating the positions of phase transitions in statistical mechanics and random graph theory.

Education and career Park entered Seoul National University in 2001 and received her B.S. in Mathematics Education in 2004. She worked as a mathematics teacher in secondary schools in Seoul from 2005 to 2011. She began her graduate studies at Rutgers University in 2014, where she received her Ph.D. in 2020 under the supervision of Jeff Kahn. Her doctoral work earned the 2022 Dissertation Prize from the Association for Women in Mathematics. She was a Member of the Institute for Advanced Study from 2020 to 2021. From 2021 to 2022 she was a Szegö Assistant Professor at Stanford University, where her postdoctoral mentor was Jacob Fox. She joined the Courant Institute of Mathematical Sciences at New York University in 2023, where she is currently an assistant professor.

Recognition In 2023, Park received the Maryam Mirzakhani New Frontiers Prize "for contributions to the resolution of several major conjectures on thresholds and selector processes". In 2024, she received the Dénes König Prize together with her coauthor Huy Tuan Pham, "for their outstanding research in discrete mathematics, in special recognition of their ingenious, short, and surprising proof of the Kahn–Kalai conjecture". The following year, she was the 2025 recipient of the Levi L. Conant Prize, given for her article "Threshold phenomena for random discrete structures" in the Notices of the American Mathematical Society.

Worked examples

Example 1 — a first encounter with Jinyoung Park (mathematician)

Start with the simplest possible case. Write down what Jinyoung Park (mathematician) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Jinyoung Park (mathematician) 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 Jinyoung Park (mathematician) 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 Jinyoung Park (mathematician)

In research: Jinyoung Park (mathematician) appears in mathematics 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 Jinyoung Park (mathematician) 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: Jinyoung Park (mathematician) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1982 births, 21st-century South Korean mathematicians, Combinatorialists, so understanding it makes those chapters shorter.
In everyday life: Look for Jinyoung Park (mathematician) 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.
