Teaching is one of my greatest passions. I have experienced great academic success at the school and university levels, and the credit goes to my amazing teachers and peers. Their positive influence on me as a student is at the core of my commitment to help out my students. I started up my tutoring career by teaching my young brother and his friends. Later I took up several jobs tutoring a small group of students in my home town.
Presently, I am a Ph.D. scholar specializing in Nanoscience. Here, I help my fellow researchers to prepare presentations, plan experiments, and interpret data.
