All schools let you choose the instructor…
NBB: Dr. Frenzle (NBB 301 for spring, neurodegenerative disease), Dr. Rosche (Neurobiochem, freshman seminars and some others as she pleases), and some others (maybe Dr. Nemenman if you wander to the computational/quantitative side) kind of lead teaching innovation in the dept. NBB also has some seminar team taught courses like drug development where they flat out have different speakers come in in such a way that balances the business and scientific perspective (note that Emory can easily have a class like this because we’re really big in pharma and also have an awesome pharmacology graduate program). There is also the very well known clinical practicum course where you actually meet patients and give case presentations on them.
Pre-med outside of NBB: Beck (biol 247-ecology, but mainly 240, organismal form and function if pre-med. A course taught superiorly to the human physiology course), Spell (biol 141/142), Abreu (biol 141/142), Eisen(several cool IDS courses, cell biology in the spring, sometimes epigenetics), Gerardo (evolutionary biology), Orloff(cancer biology), Antia(immunology), Crouse for human genetics (dry, but tests and teaches more in a way that emphasizes data analysis, which is better than Dr. Deal who keeps his class more at the level of biol 142, and is thus kind of a waste of time), Mulford/Weaver/McGill (general chemistry top 3, slight edge to Mulford/McGill), Weinschenk/Soria (ochem), any chemistry instructor for biochemistry (this is basically saying that the biochemistry offered by the biology department is inferior, especially since Escobar teaches it now) and biochem 2 when offered (in chemistry dept., Dr. Weinert will teach it. I pray she gets tenure because she’s a really good teacher. One of the few people to ever teach any sort of biochemistry course with a more problem based/case based method. Rigorous course, but really good and focuses on scientific thinking and research).
In general: You want to take the instructors that make you a) do data analysis/problem sets/case studies and b) write exams that go far beyond rote memorization. You can easily tell who these folks are because they are kind of polarizing as they are often known as good lecturers, but turn off many because they do challenge, so you’ll get a mixture of praise and fear from some of these people.
