YOKOTA Kohei
My research consisted of conducting field investigation in urban rivers and application of Bayesian statistical analyses to unveil the underlying relations between fish distribution and geomorphological features. I can support your research with fine-tuned software, allowing efficient field investigations, as well as appropriate suggestions for handling diverse data. I would also like to develop software for maximizing aquatic organisms' habitat suitability, controlling for discharge and sediment supply.

MISAWA Ryota
I have been studying accurate, stable and fast formulations of boundary element method, its related eigenvalue solver in conjunction with the Sakurai-Sugiura ( contour integral ) method, as well as topology and shape optimization problems. I am thus fluent in numerical solvers and their application to structual optimizations in computational mechanics and computational electromagnetics. I hope to apply my knowledge and experience with numerical methods to support customers' research and developments.
