Kenta Ishiguro

I am currently a postdoctoral researcher working with Alain Tchana and Renaud Lachaize at KrakOS, Grenoble INP - UGA, France. I was a project assistant professor working with Kenji Kono at sslab, Keio University, Japan. I was an associate faculty member at Hosei University working with Toshio Hirotsu. I completed my Ph.D under the supervision of Kenji Kono at Keio university, Japan.

Interests

Operating systems, Hypervisor, Software security
