Bodo's WBG Expert Talk

Talk to the experts! Join my virtual roundtable, focused on wide bandgap technology. Our goal is to keep the dialog going on, independent of any events that are hosted on fixed dates. These expert talks will build on the articles we published in the magazine, giving you the chance to ask questions to the experts out of the industry.

If you are interested in participating as an expert, please plan your article for the magazine. We will then invite you to one of the upcoming rounds. Our aim is to give as many companies as possible this opportunity, as we are sure that a wide variety of contributions is of value to everyone. Different speakers will bring new perspectives and approaches.

A huge thank you goes out to all participants of our successful April edition of Bodo’s Expert Talk, of course especially to the speakers for making this such a lively discussion!

Recordings of all previous Expert Talk sessions are now available here.

We look forward to the next episode, coming to you on July 27th.
And don’t miss the current issue of the magazine – it is waiting for you in my archive!

Below you find the articles that are addressed in my last expert talk. Recordings will be available about one week after the event.
