Mechanical Engineering

Gordon Christopher Gordon Christopher received his Ph.D. in mechanical engineering from Carnegie Mellon University under the guidance of Professor Shelley Anna. His research focused on the use of microfluidic T-junctions to manipulate droplets (see references 1-4 below). He worked extensively in the characterization of complex fluids and their use in microfluidics using both shear and extensional rheology. During his post-doctoral work as an NRC fellow at NIST, he continued to develop his skills in the modeling and characterizing of complex fluids as well as developing novel microrheology techniques (see reference 5).

Dr. Christopher's current research interests are in the fields of microrheology, microfluidics and interfacial rheology. In his lab, new methods to characterize both bulk and interfacial rheology are being developed taking advantage of the unique properties of microfluidic flows.
