Hui Lei is a computer science 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 Hui Lei rather than just read about it. In short: Hui Lei is a Chinese-American computer scientist, software engineer, and technology executive. He is known for his work in cloud computing, big data, and mobile computing.

Key takeaways

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

Reference excerpt

Hui Lei is a Chinese-American computer scientist, software engineer, and technology executive. He is known for his work in cloud computing, big data, and mobile computing. He is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) and a Director of engineering at Meta Platforms Inc.

Education Lei received a B.S. degree from Sun Yat-sen University, an M.S. degree from New York University, and a Ph.D. degree from Columbia University, all in computer science. His Ph.D. thesis was titled "Uncovering and Exploiting the Intrinsic Correlations Between File References".

Career Prior to joining Meta, Lei was a vice president at Futurewei Technologies. He was with IBM until 2018, where most recently he was Director and CTO of Watson Health Cloud, an IBM Distinguished Engineer, and an IBM Master Inventor. The projects Lei has worked on include R3 Messaging, Mercury, and Mobile Crowdsensing. He has over 90 patents to his credit. Lei was Editor-in-Chief of the IEEE Transactions on Cloud Computing from 2016 to 2019. He served on the board of governors of the IEEE Computer Society from 2021 to 2022.

Honors and awards Lei was recognized with an IEEE Computer Society T. Michael Elliott Distinguished Service Certificate in 2014. The same year, he was admitted to the IEEE Computer Society Golden Core. In 2016, Lei was named a Fellow of the IEEE "for contributions to scalable and dependable data access in distributed computing systems." A year later, he received an IEEE Computer Society Technical Achievement Award "for pioneering contributions to scalable access to real-world data."

Worked examples

Example 1 — a first encounter with Hui Lei

Start with the simplest possible case. Write down what Hui Lei 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 Hui Lei 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 Hui Lei 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 Hui Lei

In research: Hui Lei 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 Hui Lei 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: Hui Lei is common in secondary-school and first-year university syllabi. It links to neighbouring topics American business executives in technology, American computer scientists, American software engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Hui Lei 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.
