Daisuke Takahashi (mathematician) explained

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]
