Professor Aaron Panofsky is one of the most kind, thoughtful and open-minded professors I've encountered so far in my experience here in UCLA. Although I did find some of his topics in regards to this class (DIY biology / GMO) abit more dense and confusing, Prof Panofsky teaches them in a way that makes it very comprehensible. As long as you pay attention in class and rewatch lectures before your midterms, you should be good to go. And if you do want to go deeper into a certain topic, his office hours are great + he is very willing to clarify questions there too :)
