Dr. Kelly M. Schultz is an Associate Professor in the Department of Chemical and Biomolecular Engineering at Lehigh University. She obtained her B.S. in Chemical Engineering from Northeastern University in 2006 and a Ph.D. in Chemical Engineering with Professor Eric Furst from the University of Delaware in 2011 as a National Science Foundation graduate research fellow. While at Delaware, she was invited to speak in the American Chemical Society Excellence in Graduate Polymers Research Symposium and was selected as the Fraser and Shirley Russell Teaching Fellow. Following her PhD, she was a Howard Hughes Medical Institute postdoctoral research associate at the University of Colorado at Boulder working in the laboratory of Professor Kristi Anseth. As a postdoc, she was invited to participate in the Distinguished Young Scholars Summer Seminar Series at the University of Washington. She began her position as Assistant Professor at Lehigh University in 2013 and was a P.C. Rossin Assistant Professor in 2016 – 2018. Dr. Schultz was named one of TA Instruments Distinguished Young Rheologists (2014), was awarded a NSF CAREER award (2018) and the Libsch Early Career Research Award (2019). Dr. Schultz and her research group study emerging hydrogel materials developed for biological applications, such as wound healing and tissue regeneration. Of particular interest is the development of bulk and microrheological techniques that measure how 3D encapsulated human mesenchymal stem cells degrade and remodel synthetic hydrogel scaffolds during motility.

Lilian Hsiao is an assistant professor of Chemical and Biomolecular Engineering at North Carolina State University. She conducted her postdoctoral work at MIT from 2014-2016, received her Ph.D. in Chemical Engineering from the University of Michigan in 2014, and her B.S. in Chemical Engineering from the University of Wisconsin-Madison in 2008. She is the recipient of the AAAS Milligan Mason Award in 2019, an Individual Accomplishment Award from MIT Chemical Engineering for outstanding leadership, and a Rackham Fellowship at the University of Michigan for creative and outstanding dissertations. Her research group is interested in understanding the tribology of textured substrates, the microstructure and dynamics of suspension rheology, and the self-assembly of colloidal materials.

Susan J. Muller is Professor of Chemical & Biomolecular Engineering at the University of California, Berkeley where she holds the Class of 1955 Chair.  She has worked on problems related to polymer fluid mechanics, processing, rheology, and microfluidics for over 25 years at MIT, Schlumberger Cambridge Research, AT&T Bell Laboratories, and the University of California, Berkeley.  She has worked extensively in the area of viscoelastic instabilities, the role of polymer-solvent interactions in determining macroscopic flow behavior, shear-induced migration of polymers, and the behavior of DNA and other microscale objects in microfluidic devices.  Recent research on large scale flows has focused on drag reducing polymers and wormlike micellar solutions; recent work on microscale flows has focused on the design of microfluidic devices to trap and manipulate DNA, vesicles, and other microscale objects, and the use of microfluidics to make and analyze suspensions of soft particles.  She has served as Associate Dean of the Graduate Division at Berkeley, and as Program Director of the Particulate and Multiphase Processes program at the National Science Foundation.  Professor Muller holds a B.S.E. in chemical engineering from Princeton University, and a Ph.D. in chemical engineering from M.I.T.

Safa has been an assistant professor of Mechanical and Industrial Engineering at Northeastern University since 2017. Before joining Northeastern, he conducted two years of postdoctoral training at MIT (2015-17), after receiving his PhD from Case Western Reserve University in 2015. He received the best poster award of the 88th annual meeting of the Society of Rheology in Tampa, FL. His research group is generally interested in understanding the microstructure-rheology relationship in complex fluids, with focus on developing computational tools that enable investigation of mesoscale to bridge across different time and length sclaes. Rheological problems of interest that Safa pursues in his group span over dynamics of particulate suspensions, gels and self-assembled materials, viscoelastic suspensions, thixotropy and more.

Jennifer Hofmann is a doctoral student in the Department of Chemical Engineering at Stanford University, where she studies the hydrodynamics of intracellular transport with Professor Roseanna N. Zia.
