Trygve Kastberg Nilssen is an associate professor at Department of Economics and Finance at School of business and law at University of Agder. He has studied applied mathematics and has a PhD from University of Bergen and master from University of Oslo.

Nilssen’s research is within computational science and he’s been working on problems in finance, medicine and multiphase flow problems from the oil industry. This has resulted in a series of scientific papers which are published in international journals like:Journal of Energy Markets, Mathematics of Computation, Advances in Computational Mathematics, Journal of Optimization, Theory and Application, Computational GeosciencesandSIAM Journal on Scientific Computing.

In 2010 Nilssen won a “Best Paper Award” (On the optimal exercise of swing options in electricity markets) on the Energy Finance-conference in Germany.

Nilssen has held tens of presentations on international conferences in Europe, USA and Asia. He has also been a visiting researcher at University of California at Los Angeles.

Nilssen has also experience from the private sector and he has been working on development of software and simulators, e.g.  a simulator for stock selection in the stock market, a simulator of the electrical activity of the human heart and a simulator of multiphase flow in oil and gas. He has also been developing software for doing condition based maintenance in the oil- and gas industry.

At high school Nilssen was one out of five students who qualified for representing Norway in the international physics Olympiad.
