So received his B.A. degree in physics from Hamilton College, his M.S. degree in materials science from MIT and his Ph.D. degree in electrical engineering from the University of Southern California. He started his career as a research scientist at Hoechst Celanese and Motorola Corporate Research Laboratories. While at Motorola, he was instrumental to commercialization of the world’s first organic light emitting diode (OLED) displays used in mobile phones in 2000. He later became the head of OLED Research at OSRAM Opto Semiconductors. In 2005, he joined the Department of Materials Science and Engineering at the University of Florida and later became the Rolf E. Hummel Professor of Electronic Materials. He is a Fellow of the National Academy of Inventors, Institute of Electronic and Electrical Engineers (IEEE), Optical Society of America (OSA) and International Society for Optics and Photonics (SPIE).

Research interests

Prof. So’s research interest is in the area of organic and nanocrystal materials for optoelectronic device applications. He is currently studying the morphological, dielectric and interfacial effects on the properties of polymeric solar cells. So is also investigating the use of corrugated substrates to enhance the light extraction efficiency of OLEDs. His interests include:

  • Organic and molecular electronic materials and devices
  • small molecular organic materials
  • conjugated polymers and organic-inorganic hybrid perovskite materials
  • quantum dots
  • carrier transport
  • photophysics and optoelectronic devices such as light emitting devices, solar cells, novel transistors and optical sensors
