Dr. Shuai was a relief after the three weeks of Dr. Grunstein. Don't get me wrong, Grunstein was an amazing professor (and if you look him up, a figurehead in the histone field), but he went over so much material in such a short amount of time that it was difficult to keep up with him and his expectations.
Dr. Shuai had a very limited range of material, but made sure to go very in-depth, he stressed the basics so that we could build off a solid foundation once we hit the cancer lectures. He always asked us if we had questions before moving on to a new topic, and if he sensed the smallest hesitation on our part, would make sure to go over the topics that we had trouble on. He really stressed conceptual understanding of the material... on our "final" he maybe had 3 out of 7 questions that asked us to design experiments related to some of the regulatory pathways for apoptosis and cyclin... we therefore weren't expected to memorize pointless details, but to have a grasp of the concepts behind the topics. Overall, he was a great teacher, and my favorite of the MCDB M 140 Professors (who were all great to begin with)
