## Biography

A former student of École Polytechnique, Philippe Flajolet received his Ph.D. in computer science from University Paris Diderot in 1973 and state doctorate from Paris-Sud 11 University in 1979. Most of Philippe Flajolet's research work was dedicated towards general methods for analyzing the computational complexity of algorithms, including the theory of average-case complexity. He introduced the theory of analytic combinatorics. With Robert Sedgewick of Princeton University, he wrote the first book-length treatment of the topic, the 2009 book entitled *Analytic Combinatorics*.

A summary of his research up to 1998 can be found in the article "Philippe Flajolet's research in Combinatorics and Analysis of Algorithms" by H. Prodinger and W. Szpankowski, *Algorithmica* **22** (1998), 366-387.

At the time of his death from a serious illness, Philippe Flajolet was a research director (senior research scientist) at INRIA in Rocquencourt.

From 1994 to 2003 he was a corresponding member of the French Academy of Sciences, and was a full member from 2003 on. He was also a member of the Academia Europaea.
