    Research on Improving Attack Resistance of Virtual Execution Environments

    I am engaged in research aimed at identifying parts of interpreters that could be exploited in attacks, in order to devise new attack techniques and their countermeasures ahead of attackers. To support this effort, I also conduct research on automated program analysis techniques.
    Ph.D. in Information Science and Technology
