At least from 8.15 to 18.00 this is true. Here is an overview.
Dr. StephanWeber was born in Berlin. He studied electrical engineering from 1985 to 1990 at the Technical University Berlin. In 1990 he moved to the Hahn-Meitner Institute for Nuclear Physics. The focus here was the modeling of discrete semiconductors, integrated circuits, etc. (suported by the BFMT project "Model Library for Complex Analog Models). After he received his PhD (on Modeling of Field-Effect Transistors) he moved to Siemens (now Infineon Technologies) in July 1995, where he started with the design of DECT receivers. Now he is responsible for the development and concept engineering of Silizium RF power amplifiers and is also involved with special CAD topics like on-chip coils, transistor modeling, technology optimization, etc. He holds many patents on circuits and system topologies for DECT, receicers, amplifiers, bias and control circuits, etc. At home he has not much to do with electronics - anymore. However the cupboards are still overcrowded by old stuff (amplifiers, radios, power supplies, etc.), thousands of components, measurement equipment, etc.
2002 he joined Cadence VCAD in Feldkirchen close to Munich, and works in the area of IC design and EDA software.
My old professor told us "The most important skill one can learn at a university is to learn how to learn.". I do not fully agree. Even more important is fun and solid knowledge on EE basics as a foundation to work creatively.
