Dear Sir or Madam,

Over the last two years I have come to know Roberto Mart´ınez de la Cruz, who has been an MSc candidate in our group, as well as a teaching assistant for my undergraduate course in computational modelling.

Since coming to our faculty, Roberto has repeatedly demonstrated high-quality performance. This has been especially true of our course program, which many students find difficult, yet in which he has performed well above average. As a teaching assistant, Roberto has also demonstrated skills which are not directly related to academic achievement. In general he is a good communicator, and explains even abstract concepts clearly. I have also appreciated his creativity in helping to create new quiz questions.

In general our Aerodynamics MSc track provides a background which is applicable to many of the activities on the professional career. In the case of Roberto, this has included several advanced courses in computational fluid dynamics, at which he has excelled.

In summary, I would not hesitate to recommend Roberto. With kind regards,

S. J. Hulshoff

Assistant Professor, Aerodynamics Group
