Daisuke Takahashi (mathematician)

Daisuke Takahashi is a full 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]

gollark: If you store data in open formats on stuff you control with decent backups, digital media does *not* randomly disappear.
gollark: Though I looked at it a while ago and silicon or germanium might be better.
gollark: Loads of things. The highest-density is data encoded in big diamonds through different isotopes of carbon.
gollark: I mean, if it's fun, why not, but I don't think it's the most effective way to preserve data.
gollark: I prefer to etch my important data on the moon with lasers.
