<p>Greg Lawler is an awesome person and a great mathematician, and I’m really happy to see him here. I took a few classes with him in both the College and in graduate courses, and he’s a fantastic lecturer and top-notch researcher. He also fits the bill of being a UChicago math professor, inasmuch as he puts quite a bit of emphasis on undergraduate education, something I understand as rather rare for top-notch researchers in general. In his undergrad classes, he would often invite people to dinner to discuss their ambitions in mathematics, and he would always hang around the student lounges during his time off.</p>
