I took Dr. Esdin for LS2.

He is a great professor, the best I think in the LS department. While taking LS3, all I can think about is how much I miss his class. His class is straightforward and Dr. Esdin is very clear and understandable. He is super super super nice during Office Hours too. There is a lot of material and despite the fact he tries to condense it, there is still a lot of material. He only tests on his lectures slides and what he says in class so you don't need to buy the book which is super expensive. If you need to use the book, which you rarely do, you can go look at it in Powell library. Anyways, I recommend him to anyone taking LS1 or LS2. I'm actually waiting for him to teach LS1 so I can take it.

I had Dr. Esdin for LS2, Fall 2009. Professor Esdin IS the best professor I had of the LS series. His lectures are interesting; he cares about his students; he doesn't go on random tangents, etc. etc. He is perhaps the best professor you can have for LS2. (My TA taught LS2 for 6 quarters and he can confirm this.) Just go to lecture and study the lectures notes (no textbook needed) and you'll be good. He likes to focus on small details to help create a curve and such - so make sure that you get the big picture first, then focus on the details. LS2 is an interesting subject, and Esdin makes it even more interesting - I think a lot of people switched to Physiological Science after taking this course.
