Research Focus

At VIMAN Lab, we investigate novel methods to model, measure, manage and secure distributed/cloud computing applications that have real-time resource allocation needs and require high-speed networks.

With broadband access and cloud computing becoming integral in our society, end-user applications (e.g., video-on-demand, videoconferencing, remote visualization, remote instrumentation, real-time data analytics) are increasingly becoming data-intensive, mobility-supported and network-dependent. Consequently, we are motivated by the challenges in studying theoretical foundations as well as developing tools for designing/measuring/managing/securing networks and cloud platforms. We strive to deliver the Quality of Service (QoS) required for meeting the end-user Quality of Experience (QoE) expectations in applications (e.g., healthcare, advanced manufacturing, public safety, new media, bioinformatics).

    "Hacker Trackers" High School Students Summer Camp


    (Organizer: Summers@Mizzou)
    Do you like playing detective for investigating cyber attacks? Are you interested in learning tools and coding for detecting cyber attacks and developing cool visualizations to track cyber attacks? In this summer camp, you will assume the role of expert witnesses by conducting a network forensics investigation to catch cyber-criminals who were attacking a “Good online gaming” company. You will learn coding with a database and analyze attacks with a public cloud platform. You will also collect evidence to demonstrate to the jury the geographical location of the “cyber-criminal mafia” and the extent of damage caused for compensation.
