Hi. I am Jonas. I completed my Ph.D. in Physics in 2014 and worked for 8 years as a Professor in a Federal University in Brazil, where I had the opportunity to teach a wide list of topics in physics and math. I was already awarded a Humboldt Fellowship, which is a prestigious fellowship that brings high qualified academics from abroad to Germany. I am currently working as a postdoctoral fellow at the University of Konstanz. I offer private tutoring for high school and/or university-level students. I have expertise and experience in all high school topics and also in most topics at university level (classical physics, modern physics, quantum mechanics, electromagnetism, differential and integral calculus, linear algebra, vetorial calculus, and many more). Unfortunately, I don't speak German at the moment. So, I can only tutor in English, Portuguese or Spanish. I can give lessons face to face in the region around Singen - Konstanz, or online via Zoom/google meet. Please fell free to contact me in case you have some question.
