Research

The members in our group hold a wide variety of research interests from embedded systems to graphics design. We encourage ideas from different disciplines to diverge our research domain, but our group's core research focuses on the following areas. 


  
  • Intelligent medical systems
    • The goal of our intelligent medical systems research is in assisting clinicians and medical staff in the patient monitoring process and clinical diagnosis. Our work in this domain focuses on collecting and analyzing medical data from hospitals and from wearable healthcare platforms to gain a comprehensive view of patients and their symptoms. Our partnership with the Ajou University Hospital and the School of Medicine allows us access to both clinical and biosignal data (with IRB approval) from real patients. 

   
  • Low-power embedded systems and cyber physical systems
    • Miniaturized sensors collected to low-power embedded platforms will play a critical role in collecting data from the real-world in a scale that was previously impossible. Our research focuses on maximizing the capabilities of low-power, resource-limited computing platforms so that they can independently play a critical role in not only capturing the environmental characteristics, but also in autonomously analyzing and adjusting the physical world. 
      • SecureIoT (Certificate-based Security for Resource Constraint Internet of Things)

     
  • Smart devices and systems
    • Smart devices today typically refer to computing platforms such as smart phones, watches or glasses. On one perspective we are looking into how we can improve the sensing capabilities of these smart devices, by developing algorithms to calibrate the low-quality sensing data that these platforms currently provide. On another perspective, our group is performing research on designing new smart device platforms that can assist a larger population, especially for the socially weak.
