    Our Team

    International team, strong in analytics

    KYOS employs a talented team of quantitative consultants with relevant experience in energy and commodity markets. All consultants have one or more MSc. in Mathematics, Econometrics, Finance or Physics, and a large percentage holds a PhD.

    Our products and services add value. KYOS' software and advisory services contain state-of-the-art modelling techniques, and they are primarily developed to make work easier. Our consultants have worked in energy trading companies and therefore realize what the specifications of a good product are. It is our core strength to translate a sound analytical approach into a useful service.

    The team of KYOS consultants is led by Dr. Cyriel de Jong and Hans van Dijken.
