AH was born in Nagano prefecture, and took Dr. of engineering at the university of Tokyo in 1990 for industrial analytical chemistry. Since May 1997, AH has been engaged Research and education mainly in the Chikushi campus, Kyushu university. AH committed as mainly education-responsible positions of a variety of MEXT-supporting program for improving graduate school education (Initiatives for Attractive Education in Graduate Schools from 2005 to 2007, Global COE project from 2008 to 2013, Program for Leading Graduate Schools from 2012, and the other global education projects). AH made a great contribution for reorganization of Interdisciplinary Graduate School of Engineering Sciences as well as the faculty of Engineering Sciences, and is currently Senior Vice President of Kyushu University for Q-AOS, SHEAR, and Chikushi campus affairs.


AH has been engaged research topics listed below.

  • Laser-based analytical chemistry for ultrasensitive detection of environmentally and biologically important chemical species in a liquid phases.
  • Ultrasensitive detection of non-luminescent molecules in solutions by photoacoustic and thermal lensing methods.
  • Study of molecules on water by using nonlinear laser spectroscopy (second harmonic generation & multiphoton ionization), and by using synchrotron radiation.
  • Cell diagnostics with a laser fluorescence and photothermal microscopy.
  • Quantitative nondestructive evaluation and depth profiling of materials

Keywords: analytical molecular spectroscopy, laser chemistry, nonlinear spectroscopy, photothermal, single molecule detection, interfacial nanoenvironment, molecules on water, X-ray-ultraviolet correlation spectroscopy, and photochemical water-cleaning.

Relevant Countries in Asia & Oceania:

Australia, Bangladesh, China, Egypt, India, Korea, Malaysia, Myanmar, Singapore, Taiwan, Thailand
