Hands down the best story teller I've encountered in my life, he teaches a number of classes on operations that are directly applicable in business, relationships, or life in general. Also genuinely one of the most approachable, humble, thoughtful, and knowledgeable professors at the school.

This guy is so good he never gets wasted on the MBAs, the school only provides him to those who fork out 10+k for a few hours and a piece of paper... He can almost make this worth it. He teaches his students how to apply principles of psychology and behavorial economics like no other professor in the school, reinforcing "here's what you should do tomorrow". His research interests in persuasion vs. negotiation are super relevant and applicable to almost any field and he teaches how to apply these immediately.

A student favorite for good reason: His class on organisational change helps prepare students with empathy, foresight, and people skills to an extent that they forget they're going into entry level grunt roles immediately upon graduating. Hopefully they keep the notes as this material ages well.

One of the better stock analysis classes in the school, and he is the favorite professor for it. He teaches you all the tricks in terms of smoke and mirrors to add to your excel, how to perform the exact valuation analyses and data to include to make your stock predictions up to industry standard... More importantly, he teaches you how to use the right language, reference the right stocks/investors/funds, pull the most appropriate quotes from the bible (The Buffet shareholder meeting letters). Overall he teaches you how to appear in order to be respected in the industry..

Try to ignore the part where he advises you to "use your judgement" to evaluate the management (what does this mean?!) or that your guestimate of the terminal value shouldn't exceed 2/3rds of the total stock (WTF did we just spend the previous 11 weeks calculating such exact numbers for then?!?!).

His negotiations classes at CBS are second to none and he is one of the most thoughtful, insightful, and charismatic speakers in the school. His negotiations sections are rightfully some of then most bid upon classes in the school.
