Exploring science to preserve nature


Dr. Ahsan Sarwar Rana

Throughout my life, I have been many things.

I was, and still am, and I will always be a student. I guess without learning new things, a person stops to grow… I hate being stagnant. I have a doctorate in Electrical Engineering.

I am a researcher and writer and have published several journal articles in well-reputed journals. The list can be found in my google scholar profile (Dr. Ahsan Sarwar Rana). My areas of research and publications are given at the end.

I am a teacher, and currently, I am serving as an Assistant Professor at Air University where I teach undergraduate, and graduate courses. The courses I have taught are also given at the end.

Through my writing, I would love to create an awareness among people about latest science and technology, especially from topics of optics, photonics, renewable energy. From these trends we can derive technology that is environment-friendly so that we can help nature as well.
