Dr. Hirotaka Sakaue joined the University of Notre Dame in January 2015. Prior to this, he was a researcher at Japan Aerospace Exploration Agency (JAXA), Japan. He has research experiences in Germany (German Aerospace Center) and in UK (the University of Manchester) as well. With aerospace and bioengineering backgrounds, his research is on an interdisciplinary study of fluid mechanics (aerospace part) and functional chemistry (bioengineering part). Currently, he has two research columns from this interdisciplinary research: luminescent imaging and chemical flow control. The targets of these research columns are in fluid mechanics, flow control, green energy, and biomedical applications. Representative one in the luminescent imaging is the pressure- and temperature-sensitive paint technique. It involves a wide range of research topics from chemical sensor developments, optical characterizations, and unsteady flow applications in various flow regimes. Two main topics in chemical flow control are micro-fiber coating and ice-phobic coating.
