I have been working in the energy industry for over nine years now. In my opinion, the energy industry is one of the most exciting and innovative industries. Due to the various (environmental) political, social and economic changes in the energy system, this worldwide transition will accompany us for decades and never really come to an end. Together with my colleagues from consistency, I am looking forward to confront this challenge. For me, the promotion of innovation and the development of new business models is an extremely interesting and fascinating field. As a consultant, I love the challenge of getting to know new companies and bringing my skills and experience to bear. This is the only way we can develop and implement tailor-made and individual solutions for our customers.

I studied environmental engineering and business administration at RWTH Aachen University and St. Gallen (CH) Afterwards I did my PhD at the Laboratory for Machine Tools and Production Engineering in the field of Production Systems.

As a family father, time and cohesion within the family are very important to me. I enjoy the weekends at home and undertake a lot with my wife and our three children. I also enjoy spending time with my second family at the start of each week. The nice thing about consistency is the smooth transition between private and professional life. The unique selling point of consistency is the integration of both worlds. The obvious added value is that none of us has to decide between private life and career – at consistency both are possible.
