Short CV

Dr. Heike Riel is IBM Fellow and the Manager of the Materials Integration & Nanoscale Devices (MIND) group at IBM Research – Zurich, Switzerland. She is responsible for projects in the area of III-V semiconductors for applications in electronics, optoelectronics and energy harvesting and molecular electronics.

Heike Riel studied physics at the Friedrich-Alexander University of Erlangen-Nürnberg, Germany, and received a PhD from the University of Bayreuth, Germany, in 2003 for her work on the optimization of multilayer organic light-emitting devices. After an internship at the Hewlett-Packard Research Laboratory in Palo Alto, she joined the IBM Zurich Research Lab in 1998 as a PhD student, and became a Research Staff Member in 2003. From 2008 to 2014 she headed the Nanoscale Electronics Group and since 2014 she has been leading the MIND group. In 2011, she graduated with an MBA from Henley Business School. In 2013, Heike Riel was named IBM Fellow, the company's highest technical distinction and became Member of the IBM Academy of Technology.
