Master’s graduation and two free optimization courses

It’s been a wonderful two years. Despite the challenges of social distancing, I was able to take a diverse assortment of courses in optimization, economics, and human factors; participate in research projects in two different labs; present at a conference in Jeju; and write (in both Korean and English) a thesis I’m rather proud of.

- Frankfurt
