I had Professor Keller online because he was struggling with his health and the entire time he made it clear that he enjoyed teaching the class and was interested in the topics. The nicest older man I have ever met and I honestly feel honored that I was able to take this class. I liked the setup of his class and watching his lectures. I

Ed is the sweetest professor ever! He's very caring and super passionate about any subject he's teaching. I've taken 2 of his classes and the exams are very fair and the homework is not bad if you pay attention in section. I would highly recommend!!

Definitely knowledgable, an easy grader, and made attendance non mandatory which was great for remote pandemic learning. But most boring lectures I have ever had. If the course were in person we would have actually gone to river sites that may have made up for how terrible his lectures are. Would not recommend.

Im a hydro major so I took 3 classes with him. I survived fine but he spends 90% of class talking about himself and his research, so Ive basically heard his whole life story multiple times in different classes. This is pretty inefficient to actually cover content, and hes not great at explaining stuff. Nice enough person but not a great teacher.

Professor Keller was very understanding as a professor during this pandemic. His lectures weren't mandatory and he was always very friendly and welcoming to all of the students that would show up to class or office hours. He is also a very easy grader so its easy to do well in his class.

He talks A LOT and jokes a lot so it's hard to stay focused on what is actually important. But he's pretty funny and the book is interesting. He is easy going and very approachable. Slides are on Gauchospace but they don't always have words, so if you don't go to class, read the book. Writing your essays is the best way to study for MT & final.
