Brief Overview

    The Social Computing Research Lab conducts theoretical and experimental research to overcome critical emerging problems when societies and computing technologies interact closely with each other, while simultaneously enabling new applications. There is a significant emphasis within the group on addressing big-data challenges via effective data mining, data fusion and machine learning techniques, along with security and privacy of designed services and applications. The group's research is strongly multi-disciplinary involving collaborators in computer science, electrical engineering, behavioral sciences, clinical psychiatry, environmental engineering and education. Practical applications of our research are in cyber safety, digital privacy, cyber security, smart healthcare, disaster management, environmental sustenance and more. Students are constantly encouraged to innovate and transition outcomes from the lab to industry.

Current/ Recent Research Projects

  • Multi-disciplinary and Privacy Preserving Techniques to Combat Cyber Risks among Teens
  • - This project integrates data mining techniques, learning algorithms, social science theories and privacy expectations of end users to design context and data driven solutions to model, and detect risks to teens emanating from cyber use. This project is supported by National Science Foundation [Project 1] [Project 2].

  • Assessing Human Behavior from Internet Usage
  • - This project designs techniques for extracting meaningful data emerging from human interactions with emerging technologies like Internet and Smart-Phones, and subsequently design classification algorithms to understand human behavior. Applications of this research are in pervasive mental health care, advancing cyber security and detecting cyber bullying. This project is supported by National Science Foundation [Project].

  • Designing Citizen Science Applications for Water Management
  • - Modern smart-phones come equipped with a number of sensors like accelerometers, gyroscopes, humidity, light-intensity sensors and more. This project designs effective algorithms to enable real-time sensing, transmission and processing of such multi-modal sensor data from a number of devices to enable new citizne science applications in the realm of water management, disaster prediction, environmental sustenance and more. This project is supported by National Science Foundation [Project].

  • A Multi-disciplinary Framework to Model Cyber Criminals
  • - This project integrates theories from criminology with learning algorithms in computer science to understand the evolution of crimes and criminals in cyber space. Applications of this project lie in understanding group behavior of cyber criminals, early detection and intervention for cyber criminals, and early detection of cyber crimes. This project is supported by National Science Foundation [Project].

  • Secure Communications in Wireless Sensor Networks
  • - This project designs and deploys cross-layer algorithms for enhnacing security and privacy of wireless sensor networks operating in the presence of adversaries.

  • Trustworthy, Secure and Privacy Preserved Communications in Vehicular Networks
  • - This project designs algorithms integrating theories from computer sciences (wireless communications, information theory and machine learning) with theories from transportaiton engineering (platoon dispersion and level of service) to enhance trust, security and privacy in emerging intelligent transportation systems.

  • Protecting Information Confidentiality in Critical Infrastructure Systems
  • - This project designs algorithms for protecting confidentiality in modern critical infrastructures like Smart-Grids which are characterized by tight cyber-physical interactions. The algorithms designed seamlessly integrate network topology design, formal methods and control theory.
