I had a ton of fantastic professors over the past four years...it's crazy to think about the number of hours I spent with some of them (multiple classes over multiple semesters, in lab, etc)! I have really fond memories of almost all of my professors, and Phil's right that pretty much every professor you'll have at Hopkins is top notch in their field (my cog sci professor was awarded the equivalent of his field's Nobel last year - so cool! - and yet he is still down to earth, says Hi in the hallway, and suggested that we have class outside. often.).
Some of my favorites:
* Paul Smolensky (cognitive science) as mentioned above. Brilliant, but able to bring his content down to an understandable level without "dumbing it down" to the point where it didn't mean anything substantial - I learned SO much, without really feeling like I was trying hard. Instead, it just seemed interesting, and I wanted to keep reading more and more.
* Stefanie DeLuca (sociology) and Steve Plank (sociology) - two young professors hired relatively recently, with great drive & motivation to teach about their passion - sociology of education. Really inspiring, great advisers, and willing to sit and chat about current events in the field, future plans, or interesting articles from the news. Happy to meet at Starbucks, too - always a plus!
* Barksdale Maynard (art history) - yeah, it's a weird name, but he's really that cool. "Landed southern gentry turned Delaware architecture aficionado" is probably the best way to describe him. Encyclopedic knowledge, great slides, funny anecdotes about everything and everyone; generally interested in making sure that students got a lot out of his class. He would always encourage students to check in with him about their paper topics and would help with outlines, sources, etc.
* Qiao Zhang (math). Absolutely a dream. Wrote PERSONAL comments on 200+ calc II students' tests, commenting on what they did well and their areas to focus on in the future. Does problems in class & gives you time to try it on your own, so that you can see whether you got the hang of it or need to go home and review. Made me want to go to early morning math - I didn't think that was possible.
* Stewart Hendry (neuro). Michelle B. & Tanmay love him for good reason; he's funny & explains complicated things in easy ways. His on-board diagrams can get crazy, but they somehow seem easy to follow no matter what. Focuses on both details and the big picture, to make sure that even when you forget specifics, you'll still know why you should care in the first place.
* Larry Raifman (psych). Adjunct (part-time) professor trained as a lawyer and PhD in psych. Teaches fascinating classes on Law & Psych and Behavioral Finance. Tells good stories, always has something relevant to talk about from his work that day. Showed me how you can mix disciplines across traditional boundaries and find a place/job that's right for you.
