Dr. Ammar Ahmed Khan
Associate Professor
Syed Babar Ali School of Science and Engineering
Dr. Ammar Khan completed his PhD studies from the University of Cambridge. The focus of his PhD research was studying the application of disc-like (discotic) liquid crystals as hole transport layers in hybrid organic/in-organic dye-sensitized and perovskite solar cells. Furthermore, he also studied the interaction of liquid crystalline phases with two-dimensional graphene layers for display and lasing devices. Prior to his PhD, Ammar completed his Master of Philosophy (M.Phil) degree in the Engineering Department at the University of Cambridge, as a member of St Edmund’s College. His MPhil research was focused on the development of random lasers using Organosiloxane Smectic A liquid crystals as a distributed resonant cavity. Ammar is also a LUMS alumni and graduated from LUMS with a BS in Electrical Engineering.
At present, the focus of Dr. Ammar’s research is understanding self-assembly mechanisms of liquid crystalline physical gels, and apply them to DSSCs to increase the stability and lifetime. Furthermore, the interaction of organic-semiconductors with two-dimensional materials is also being investigated for chemical and biological sensing applications.
