Biography

After graduating from the National College Vasile Alecsandri in Galați, he studied at the University of Bucharest, where he was student of Grigore C. Moisil and Solomon Marcus.[2] Calude received his Ph.D. in Mathematics from the University of Bucharest under the direction of Solomon Marcus in 1977.[3]

He is currently chair professor at the University of Auckland,[4] New Zealand and also the founding director of the Centre for Discrete Mathematics and Theoretical Computer Science.[5] Visiting Professor in many universities in Europe, North and South America, Australasia, South Africa, including Monbusho Visiting Professor, JAIST, 1999 and Visiting Professor ENS, Paris, 2009, École Polytechnique, Paris, 2011; Visiting Fellow, Isaac Newton Institute for Mathematical Sciences, 2012; Guest Professor, Sun Yat-sen University, Guangzhou, China, 2017–2020; Visiting Fellow ETH Zurich, 2019. Former professor at the University of Bucharest. Calude is author or co-author of more than 270 research articles and 8 books,[6] and is cited by more than 550 authors.[7] He is known for research in algorithmic information theory, quantum computing, discrete mathematics and history and philosophy of computation.[8]

In 2017, together with Sanjay Jain, Bakhadyr Khoussainov, Wei Li, and Frank Stephan, he announced an algorithm for deciding parity games in quasipolynomial time.[9] Their result was presented at the Symposium on Theory of Computing 2017[10] and won a Best Paper Award.[11]

Calude was awarded the National Order of Faithful Service in the degree of Knight[12] by the President of Romania, Mr. Klaus Iohannis, in June 2019.
