Excellent professor. She is engaging, high energy, and knowledgeable. I would take any class with her.
Her slides are excellent and comprehensive, but you'll definitely miss a level of understanding if you don't go to class. Her assignments and lectures are a nice blend of theoretical and applied.
A friend of mine once asked her about debugging and the next class she went up to my friend personally and gave them a paper on debugging in R. She is that personable, and she really cares.
I can't say enough good things about her.
