Many computer security problems stem from buggy software. Attackers exploit software bugs to infiltrate systems and install malicious software (malware) such as viruses. Therefore, it is imperative to find bugs before an attacker can exploit them and to detect malware prior to infection. The primary goal of my research is to assure software security. I analyze programs to find bugs and to detectmalicious functionalities; studymalware and offensive techniques in order to develop defensive mechanisms; and engineer software that is secure and reliable.
