Reference excerpt

Rüdiger Leo Urbanke (born 1966) is an Austrian computer scientist and professor at École Polytechnique Fédérale de Lausanne.

Life Urbanke studied at the Technical University of Vienna with the diploma as an electrical engineer in 1988 and at the Washington University in St. Louis with the master's degree in 1992 and his doctorate in 1995 under the supervision of Bixio E. Rimoldi. He then worked at Bell Laboratories.

Career From 2000 to 2004 he was an Associate Editor of the IEEE Transactions on Information Theory. From 2009 till 2012 he was the head of the I&C Doctoral School and in 2013 he served as a Dean of I&C.

Distinctions Urbanke is a co-recipient of the 2002 and the 2013 IEEE Information Theory Society Best Paper Award, a recipient of the 2011 IEEE Koji Kobayashi Computers and Communications Award, the 2014 IEEE Richard W. Hamming Medal and the 2023 Claude E. Shannon Award. He was selected as an IEEE Distinguished lecturer by the Information theory society for 2013-2014

and received a STOC Best Paper Award in 2016.

Worked examples

Example 1 — a first encounter with Rüdiger Urbanke

Start with the simplest possible case. Write down what Rüdiger Urbanke 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 Rüdiger Urbanke 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 Rüdiger Urbanke 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 Rüdiger Urbanke

In research: Rüdiger Urbanke 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 Rüdiger Urbanke 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: Rüdiger Urbanke is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 births, Academic staff of the École Polytechnique Fédérale de Lausanne, Austrian computer scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Rüdiger Urbanke 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.
