Daisuke Takahashi is a professor of computer science at the University of Tsukuba,[1] specializing in high-performance numerical computing.
Education and career
Takahashi received a bachelor's degree in engineering in 1993 and a master's degree in engineering in 1995, both from Toyohashi University of Technology. He completed a Ph.D. in information science from the University of Tokyo in 1999. After working as a researcher at the University of Tokyo and at Saitama University, he joined the University of Tsukuba in 2001.[2]
Research
Takahashi's works include several records of the number of digits of the approximation of Pi.[3] His work on the computation of Pi has inspired his former student Emma Haruka Iwao, who broke a new record on March 14, 2019.[4]
In 2011, he was part of a team from the University of Tsukuba that won the Gordon Bell Prize of the Association for Computing Machinery for their work simulating the quantum states of a nanowire using the K computer.[5]
He is also known for his research on the Fast Fourier transform,[6][7][8] and is one of the developers of the HPC Challenge Benchmark.[9]
