professor
Shahriar Shahramian

The ultimate educator! It is too bad he is an adjunct professor and not full time... Other profs should attend his lecture to learn how to teach complex materials. I do find him intimidating... But that is probably my insecurity. He has a scary level of mastery of a wide range of topics. Oh did I mention he has a youtube channel?! yeah... he has his own lab at home. Search for "the signal path".

One of the best classes I have taken at Columbia so far. I studied under him for analog electronic circuits. The manner in which he navigates through various concepts intuitively is amazing. At the same time, he also makes you think and interact during the class. I used to look forward to this lecture every week. I strongly recommend taking any course he is teaching.

The gold standard in teaching and knowledge. The class even had lots of people who would come to listen to the lectures and actually asked questions and engaged with the prof. It looks like he is teaching something new next year. It doesn't matter what he teaches, take the course!

Absolutely amazing class. Although very challenging. Shahriar is an absolutely amazing professor, he's a great lecturer and cares about his students actually learning the material. That said, there is a lot of material to learn in this class, which covers transitor-level amps and feedback. Most of the learning curve is building a familiarity and intuition with the material, and so it takes a ton of time. Even if it seems simple when he goes through an example in class (he makes it look ridiculously easy) you need to put in time outside of class. Right at the beginning Shahriar told the class that we needed to put in 20-30 hours a week in this class, and when we didn't believe him we all failed the midterm. So put it the time. He was nice enough to weigh the second midterm and final more than the first, I don't think anyone actually failed the class although there were more than a few who dropped out. Altogether, an amazing class that simply takes a lot of work, taught by a an absolutely amazing prof. Shahriar also has a video blog (thesignalpath.com) that has a few gems in it. He's great, one of the best professors I've ever had.
