BioDerek Fong's research in environmental and geophysical fluid dynamics focuses on understanding the fundamental transport and mixing processes in the rivers, estuaries and the coastal ocean. He employs different methods for studying such fluid processes including laboratory experiments, field experiments, and numerical modeling. His research projects include studying lateral dispersion, in stratified coastal flows, the fate and transport of freshwater in river plumes, advanced hydrodynamic measurement techniques, coherent structures in nearshore flows, bio-physical interactions in stratified lakes, fate of contaminated sediments, and secondary circulation and mixing in curved channels.
Derek teaches a variety of classes at both the undergraduate and graduate level. Some of the classes he has offered include Mechanics of Fluids; Rivers, Streams and Canals; Transport and Mixing in Surface Waters; Introduction to Physical Oceanography; Mechanics of Stratified Fluids; Dynamics of Lakes and Reservoirs; Science and Engineering Problem Solving using Matlab; the Future and Science of Water; Hydrodynamics and Geophysical Fluid Dynamics.
Prior to coming to Stanford, Derek spent five years at the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution studying the dynamics of freshwater plumes for his doctoral thesis. He has also served as a senior lecturer at the University of Washington, Friday Harbor Laboratories in Friday Harbor, Washington.

Current Research and Scholarly InterestsThe Fordyce Lab is focused on developing new instrumentation and assays for making quantitative, systems-scale biophysical measurements of molecular interactions. Current research in the lab is focused on three main platforms: (1) arrays of valved reaction chambers for high-throughput protein expression and characterization, (2) spectrally encoded beads for multiplexed bioassays, and (3) sortable droplets and microwells for single-cell assays.

BioThe properties of ultrathin polymer films are often different from their bulk counterparts. We use spin casting, Langmuir-Blodgett deposition, and surface grafting to fabricate ultrathin films in the range of 100 to 1000 Angstroms thick. Macromolecular amphiphiles are examined at the air-water interface by surface pressure, Brewster angle microscopy, and interfacial shear measurements and on solid substrates by atomic force microscopy, FTIR, and ellipsometry. A vapor-deposition-polymerization process has been developed for covalent grafting of poly(amino acids) from solid substrates. FTIR measurements permit study of secondary structures (right and left-handed alpha helices, parallel and anti-parallel beta sheets) as a function of temperature and environment.
A broadly interdisciplinary collaboration has been established with the Department of Ophthalmology in the Stanford School of Medicine. We have designed and synthesized a fully interpenetrating network of two different hydrogel materials that have properties consistent with application as a substitute for the human cornea: high water swellability up to 85%,tensile strength comparable to the cornea, high glucose permeability comparable to the cornea, and sufficient tear strength to permit suturing. We have developed a technique for surface modification with adhesion peptides that allows binding of collagen and subsequent growth of epithelial cells. Broad questions on the relationships among molecular structure, processing protocol, and biomedical device application are being pursued.

BioFraser-Smith's research focuses on the use of low frequency electromagnetic fields, both as a means of probing (1) the interior of the earth, and (2) the space environment near the earth, as well as for communicating with, and detecting, objects submerged in the sea or buried in the earth, and for detecting changes taking place in the Earth and the near-Earth space environment.
