  • 03/2020 – The iPower3Es group virtualizes 95% of our research operations because of COVID-19.
    • This is a new challenge for us, but it also gives us a great opportunity to optimize our work a lot better with remote designing, testing, and reporting.
    • We are still moving ahead as fast as we can with our interesting projects.

Welcome to iPower3Es

Our research mission is to address challenges in co-optimizing efficiency and size with performance in different electronic systems and applications, including:

  • High-performance computing and data centers
  • Robots: futuristic ones
  • Mobile and automotive devices
  • DC-houses and DC-buildings
  • Low-power biomedical implants
  • Internet of Things (IoTs)


Our team combines individuals who love what we are doing for future energy-efficient electronics systems. We strongly support diversity in our group, department, and school where creativity is fostered together with a strong work ethic. And also very importantly, we have fun. 

We are always looking for good team members. Outstanding and self-motivated students interested in joining the iPower3Es group are recommended to contact Prof. Le directly.
