In 2009, Khalid started his own lab at Emory University, where he currently investigates biophysical aspects of receptor-mediated cell signaling. To achieve this goal, his group has pioneered the development of molecular force probes and nano-mechanical actuators that are integrated with living cells. These materials are used to investigate the molecular mechanisms of a number of pathways where piconewton forces are thought to be important. These pathways include the Notch-Delta pathway, T cell receptor activation and the integrin-based focal adhesion pathway.
The David G. Lynn Group at Emory University works to understand the structures and forces that enable supramolecular self-assembly, how chemical information can be stored and translated into new molecular entities, and how the forces of evolution can be harnessed in new structures with new function. Some of our current research areas include the origins of prokaryotic and eukaryotic pathogenesis, template directed polymerization and dynamic combinatorial systems, amyloid diseases and protein self-assembly, and intelligent materials.
