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.
