Our research group focuses on implementing advanced statistical and mathematical methodology in the area of network security. The members of our group range from computer scientists and networking experts to hardware designers and mathematicians. Our goal is to improve the speed and efficiency of detection methods for network and behavior anomalies. We collaborate with several network security oriented organizations and companies to help them with difficult tasks related to advanced processing of observed network flows and network packets.
