I graduated with Ph.D. in physics and MS in electrical engineering from Purdue and then joined Cornell University as a scientist. Last year I moved back to Purdue again. At Purdue I taught undergraduate physics for 5 semester and while at Cornell I tutored all level physics for 2 years.
I take the time to grasp students, understanding of the subject and then try to make the subject fun. this way students can grasp the complicated abstract ideas easily.
