Biography

I received my B.E., M.E., and Ph.D. degrees in engineering in 2000, 2002, and 2005 from Keio University, Yokohama, Japan. From 2005 to 2012, I was with the NTT Cyber Space Laboratories (now NTT Media Intelligence Laboratories), Nippon Telegraph and Telephone Corporation (NTT). From 2010 to 2011, I was also a visiting researcher at Victoria University of Wellington. In 2013 I came back to New Zealand and was appointed as a Lecturer at the University of Canterbury, Christchurch. Then in 2014, I joined the Department of Mechanical Engineering as a Senior Lecturer in Mechatronics where I mainly teach electronics and computer engineering courses for the Mechatronics programme. I am also the Deputy Director of the Acoustics Research Centre at the Department of Mechanical Engineering.

Research | Current

Since I was studying towards my PhD I specialised in audio and acoustic signal processing particularly focusing on microphone arrays which is a technology that enables us to emphasise sound arriving from particular directions/locations.

After I received my degree I worked in industry for nearly 8 years where I had many opportunities to utilise my expertise in developing commercial products as well as growing my academic career. Because of this industrial experience the majority of my research focuses on problems in the real world. I always try to invent technologies that are practically effective and feasible but are also supported by theoretical principles. Some of my inventions have been adopted in commercial products which have been attracting many users/customers' interests.

Besides audio and acoustic signal processing, recently I am also interested in wider fields related to sound such as speech, audiology, psychoacoustics and linguistics.
