Having worked for more than 10 years as a researcher in Physics, I am currently working as a teacher for Math, Physics and Chemistry for school students in Germany. I am involved in the teaching of these subjects from elementary school to high-school level. Meanwhile, having worked in Universities worldwide, I gathered experience in teaching university/ college students in more specialized Math, Physics and Chemistry subjects (Bachelor and Master), in close connection to relevant lab courses (where applicable). All this experience has allowed me to gain a more universal overview on these demanding and important subjects, which I would like to transmit to the future generations. My personal motto: "Tell me and I forget, teach me and I may remember, involve me and I learn."
