Professor Pimentel is the GOAT. He gave lectures in a very very very engaging way and is very easy in terms of leaving doable and interesting assignments.

Involves a lot of maths and stats in this class, but are all super helpful in terms of understanding RNA seq and underlying algorithms. He put a lot of effort into teaching this class and have very well prepared material.

Although I would appreciate he goes beyond RNA sequencing and maybe go through other stuff like proteomics data. But he's exams and HWs are all pretty fair and he offers extra credit opportunities that worth 5% of your grade in total.

His OH are super helpful and he is doing a wonderful job in explaining concepts during class. I would definitely recommend everyone taking this class, especially if you're doing RNA seq related research work. I honestly wish he will be teaching more lectures in the future cuz it's such an honor to take the class with such responsible and helpful professor.

This class was still in the works as I was taking it. It was a challenge for the professor to teach in a way that made sense to both the CS-focused students and the biology-focused students. I hope he figured things out and refined this course a little more. It was overall fairly easy but disorganized.
