Video: Paul Braun on 3D photonic crystals

Using epitaxial growth avoids defects and results in a crystal with potential applications in metamaterials, lasers, and solar energy.

29 September 2011, SPIE Newsroom. DOI: 10.1117/2.3201109.02

Paul Braun is a professor of materials science and engineering at the University of Illinois at Urbana-Champaign.

The Paul Braun Research Group performs research in the fields of materials chemistry, polymers, biomaterials, organic and inorganic self-assembly, electronic materials and photonics. Braun's research focuses on understanding and exploiting self- and optically directed-assembly for the synthesis of highly functional nano and microstructures. Through this approach, Braun has created unique 3D optical devices, advanced rechargeable batteries, self-healing coatings, and 3D biological scaffolds.

He has published more than 100 papers, and is co-inventor on 10 patents and patent applications, including several which are licensed by Autonomic Materials Inc., a company he co-founded with other faculty at Illinois to commercialize self-healing materials.

Braun received his PhD in materials science and engineering from the University of Illinois in 1998. Following a one-year post-doctoral appointment in the Condensed Matter Physics Research Department at Bell Labs, he joined the Illinois faculty in 1999. He currently holds a primary appointment in the Department of Materials Science and Engineering, and is affiliated with the Beckman Institute, the Frederick Seitz Materials Research Laboratory, the Micro and Nanotechnology Laboratory, and the Department of Chemistry.

In 2010, Braun received a Friedrich Wilhelm Bessel Research Award from the Alexander von Humboldt Foundation.

He was interviewed for SPIE Newsroom in August 2011.
