Bjorn Tyreus is the principal of SySim Consulting LLC. Bjorn holds a B.S. degree in Chemical Engineering from the Royal Institute of Technology, Stockholm, Sweden and M.S. and Ph.D. degrees in Chemical Engineering from Lehigh University, Bethlehem, Pennsylvania.
Bjorn has over 40 years of industrial experience, including employment with Unifos, British Petroleum, Nobel Kemi, and DuPont, from which he retired as a DuPont Fellow after 33 years of service.
Bjorn specializes in the analysis and operation of chemical- and biochemical processes of all scales. He brings deep knowledge of thermodynamics, transport phenomena, process dynamics and control to the table for each assignment.
Dynamic models are often tools in Bjorn’s analysis of a process. The models vary in complexity and scope, depending on the need, and Bjorn has found it to be most efficient to write and implement these models from first principles using Object-Oriented Programming languages such as C++, Java, and Swift.
