Hello, I am an experienced professor in the field of physics for the past 20 years. Teaching was always my passion. My inspiration is to make this world better place with the power of education. I worked in different environments ranging from Public colleges to private colleges and dealt with students of all the ages. I do understand the nuances of teaching and fortunately with all the experience that I have gained from all these ages, I can come down to the level of the student and teach them in a way where they can understand the subject. I strongly believe that unless the student starts imagining the particular topic in their mind, the cannot get the real essence of the subject. I am here with all this experience have developed this unique way of teaching so that no student is left behind.
Hope we learn together and make this world a better place .
