If you're stuck or confused he will go out of his way to help. He genuinely wants his students to do well and his classes usually have a high average. He lectured with powerpoints for most of the semester which made it hard to pay attention/follow but as long as I read the book homeworks and exams were totally do-able. As a bonus his accent is fun!

Great professor and the class is interesting. He does a lot of proofs so that might not be most people's style. Just make sure to read the book. He really likes fluid dynamics.

Prof. Roldan was very open to student feedback, which was refreshing compared to a lot of the other older engineering profs at UW. He really wanted the students to grasp the important and basic fluid concepts and seemed to really care about the class. However, he did a lot of derivations and could have spent more time on example problems.

Roldan cares a lot about the class. However, he focusses too much on proofs and derivations. The lectures can be boring and somewhat unhelpful in actually solving the problems. Tests are extremely fair and reflect the material covered by the homework.
