hondo in seattle Posted October 6, 2023 Share Posted October 6, 2023 Urschel grew up in Buffalo, graduated from Canisius, became a Baltimore Raven, and just got a job as a math professor at MIT. He wrote his Ph.D. thesis on "Graphs, Principal Minors, and Eigenvalue Problems" and has published over a dozen peer-reviewed papers. All by the age of 32. Makes me feel like I haven't tried hard enough. 2 1 1 6 Quote Link to comment Share on other sites More sharing options...

Makes me feel like I haven't tried hard enough. I was an honors math major in college and read briefly the paper. https://math.mit.edu/~urschel/publications/thesis.pdf I agree with you I did not work hard enough but I got tired of school taking whatever work I could to pay bills. At one point I was being chased out of lounges for sleeping there and sleeping in office at my job since I had no housing. https://dspace.mit.edu/handle/1721.1/140006 2 Quote Link to comment Share on other sites More sharing options...

hondo in seattle Posted October 6, 2023 Author Share Posted October 6, 2023 5 minutes ago, LabattBlue said: Let alone understand what it means. 😂 If you don't want to read the whole thesis, Urschel provided a short summary: "This thesis considers four independent topics within linear algebra: determinantal point processes, extremal problems in spectral graph theory, force-directed layouts, and eigenvalue algorithms. For determinantal point processes (DPPs), we consider the classes of symmetric and signed DPPs, respectively, and in both cases connect the problem of learning the parameters of a DPP to a related matrix recovery problem. Next, we consider two conjectures in spectral graph theory regarding the spread of a graph, and resolve both. For force-directed layouts of graphs, we connect the layout of the boundary of a Tutte spring embedding to trace theorems from the theory of elliptic PDEs, and we provide a rigorous theoretical analysis of the popular Kamada-Kawai objective, proving hardness of approximation and structural results regarding optimal layouts, and providing a polynomial time randomized approximation scheme for low diameter graphs. Finally, we consider the Lanczos method for computing extremal eigenvalues of a symmetric matrix and produce new error estimates for this algorithm." Typical locker room jock talk. 2 Quote Link to comment Share on other sites More sharing options...
TheBrownBear Posted October 6, 2023 Share Posted October 6, 2023 Great story! Congrats to John! Also, it's pretty funny to think about going from a profession where your colleagues are guys like Tyreek Hill to becoming an MIT professor. 1 Quote Link to comment Share on other sites More sharing options...

WhoTom Posted October 6, 2023 Share Posted October 6, 2023 42 minutes ago, Don Otreply said: And? 😂 Several years ago, one of my colleagues interviewed for a professor's position at Purdue University. (He and I taught at a community college, and he had a side gig as an engineer because he was a workaholic.) The interviewer asked him about publications and he mentioned the textbook he'd written. Unfazed, the interviewer responded, "So that's just the one textbook?" Then he asked about any other honors of note and my friend said, "I have a patent in my name." Predictably, the interviewer followed up with, "So that's just the one patent?" Sheesh. 🙂 2 Quote Link to comment Share on other sites More sharing options...
