Shortly after learning he had been granted tenure Tuesday, Northwestern University mathematics professor Hugh Botkin told reporters that the promotion has motivated him to work harder than ever before in his chosen field. I was able to get this far in my career by publishing as many papers as possible and carefully negotiating departmental politics, but now the real work begins, said Botkin, 43, whose tenured faculty position ensures his employment until he voluntarily exits the job or dies. Im going to start teaching a lot more classes, advise as many Ph.D. candidates as possible, and voluntarily extend my office hours so I can provide students with as much one-on-one time as they need. Tenure is a huge honor, but it also comes with a lot of responsibility. From now on, anyone who enrolls in one of my classes can be certain my top priority will be how I can best serve them as a professor. Sources later confirmed Botkin was up half the night poring over teacher evaluations from his students and thinking about ways he could improve his lecturing style.
