## Lukas Wessels

**About Me **

I am currently a visiting scholar at the Georgia Institute of Technology in Atlanta hosted by Andrzej Święch and funded by a fellowship of the German Academic Exchange Service (DAAD). Previously, I completed my PhD at Technische Universität Berlin and the Berlin Mathematical School. My supervisor was Wilhelm Stannat.

**Book Recommendations**

These are some books that speak to me as a mathematician and have informed the way I think about my career.

- Timothy Gowers, June Barrow-Green, and Imre Leader (eds.):
*Princeton Companion to Mathematics*. Contains introductions to (almost) all areas of modern pure mathematics. Great to broaden the mathematical horizon. - Paul R. Halmos:
*I Want to be a Mathematician*(freely available). Paints a good picture of what it’s like to be a professional mathematician in the US: Starting from high school, going through undergrad, grad school, postdoc, all ranks of professor and a department chair. - Allison K. Henrich, Emille D. Lawrence, Matthew A. Pons, and David G. Taylor (eds.):
*Living Proof*(freely available). Tells the stories of 41 mathematicians and how they got to where they are now, highlighting obstacles they had to overcome on their journeys.
