If you have an opportunity to take him, pull the trigger. Without a doubt the best professor I've had at Columbia. I switched in to his CC section after the first semester (not knowing who he was) and it might have been my best academic decision yet. He's knowledgeable on every text and pushes for a more diverse selection of literature. Also very athlete-friendly but does not treat athletes any more special than other students. Includes field trips (movies) and activities (mock trials, organized debates, etc.) to keep us engage. Also a lenient grader. I went from a B- essay writer to a A- essay writer.
