Reference excerpt

Yael Tauman Kalai (Hebrew: יעל טאומן קלעי) is a cryptographer and theoretical computer scientist and the Ellen Swallow Richards Professor at MIT in the Computer Science and Artificial Intelligence Laboratory. Previously, she worked as a Senior Principal Researcher at Microsoft Research New England.

Education and career Kalai graduated from the Hebrew University of Jerusalem in 1997. She earned a master's degree in 2001 at the Weizmann Institute of Science, working with Adi Shamir, and then completed a PhD advised by Shafi Goldwasser at MIT in 2006. After postdoctoral study at Microsoft Research and the Weizmann Institute, she became a faculty member at the Georgia Institute of Technology. She took a permanent position at Microsoft Research in 2008 and became a professor at MIT in 2024. She serves on the Scientific Advisory Board of the Simons Institute for the Theory of Computing.

Contributions Kalai is known for co-inventing ring signatures, which have become a key component of numerous systems such as Cryptonote and Monero (cryptocurrency). Subsequently, together with her advisor Shafi Goldwasser, she demonstrated an insecurity in the widely used Fiat–Shamir heuristic. Her work on delegating computation has applications to cloud computing.

Recognition Kalai was elected a Fellow of the International Association for Cryptologic Research in 2022 for foundational contributions in delegated computation and leakage-resilient cryptography, and service to the cryptographic community. Kalai was an invited speaker on mathematical aspects of computer science at the 2018 International Congress of Mathematicians. Her master's thesis introducing ring signatures won an outstanding master's thesis award and her MIT PhD dissertation was awarded the George M. Sprowls Award for Outstanding PhD Thesis in Computer Science. She was co-chair of the Theory of Cryptography Conference in 2017. She was awarded the 2022 ACM Prize in Computing "for breakthroughs in verifiable delegation of computation and fundamental contributions to cryptography".

Personal Kalai is the daughter of game theorist Yair Tauman. Her husband, Adam Tauman Kalai, works at OpenAI.

Worked examples

Example 1 — a first encounter with Yael Tauman Kalai

Start with the simplest possible case. Write down what Yael Tauman Kalai claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, 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 Yael Tauman Kalai 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 Yael Tauman Kalai 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 Yael Tauman Kalai

In research: Yael Tauman Kalai appears in computer science 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 Yael Tauman Kalai 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: Yael Tauman Kalai is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American women, American computer scientists, American cryptographers, so understanding it makes those chapters shorter.
In everyday life: Look for Yael Tauman Kalai 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.
