Excerpt from student nomination: “As a classroom teacher, Prof. Levchenko is exceptional at explaining difficult concepts. He is really good at challenging students with homework problems, which are very involved and demanding but [helps them] understand materials and develop invaluable skills as a physicist. […] On top of being extremely competent in his research, he cares deeply about his students on a personal level, making sure students are doing ok in general in life and opening many doors for professional activities. As an aspiring theoretical physicist, Prof. Levchenko is someone I would not only like to work with but also want to be like when I reach that stage.”
