Professional Education

• Doctor of Philosophy, Osaka University (2007)
• M.S., Osaka University, Osaka, Japan Medical Physics and Engineering (2004)
• B.S., Osaka University, Osaka, Japan Radiological Technology Science (2002)

Faculty Advisor

• Paul Keall

Research Interests

My research interests focus on the development and application of functional imaging techniques for improving the therapeutic ratio of radiotherapy. I'm currently working with Dr. Paul Keall on the development and investigation of a novel functional imaging technique for pulmonary ventilation based on 4D-CT, and its application to lung cancer radiotherapy for adaptive functional avoidance.
