Intern from the Eindhoven University of Technology

yorrick vissers Yorrick Vissers, a master student at the TU Einhoven visited the Chair of Process Dynamics and Operations. He spent three months, from September 2014 to December 2014, within our group. During this time, he worked on an optimization framework for distributed management in the scope of the European project DYMASOS.

Congratulations to Professor Ignacio E. Grossmann


The Chair of Process Dynamics and Operations would like to congratulate Professor Ignacio E. Grossmann on his 65th birthday wishing him many successes in the years to come. On this occasion, Elsevier journal Computers and Chemical Engineering published a special issue entitled "A Tribute to Ignacio E. Grossmann".

Professor Ignacio E. Grossmann, an academic son of Professor Roger Sargent from Imperial College, is a highly influential and leading researcher in process systems engineering. His research over the last forty years have had a unique influence and un-parallel impact in defining, shaping and substantially advancing process systems engineering to a key mainstream scientific engineering field of its own. Among many received awards and honors, Professor Grossmann became a Doctor in Engineering Honoris Causa at the TU Dortmund in 2012.

Visit from the University of Valladolid

UVA Marti Bueno

Two students from the University of Valladolid visited the chair of process dynamics and operations.

Juan Bueno, an Erasmus exchange student, spent nine month from October 2013 to June 2014 within our group. During this time he worked on integration of different control modules of a pipeless plant. The pipeless plant was built by the chair in the scope of the MULTIFORM European project.

Rubén Martí, a PhD student, stayed at the group from April 2014 for three months. During this time he worked on the challenges of two-stage stochastic programming. His main focus was the illustration of different decomposition techniques (price-driven coordination and augmented Lagrangian method) to decompose the problem of two-stage stochastic programming into several deterministic problems.
