Biography

Sandra M. Troian is a Professor in the Department of Applied Physics and Materials Science at the California Institute of Technology. She obtained her B.A. from Harvard University in 1980, followed by an M.S. from Cornell University in 1984, and her Ph.D. in 1987. As a Moore Distinguished Scholar at Caltech from 2004-2005, she has contributed significantly to the field of micro/nanoscale fluidic systems. Her research interests include the dynamics and stability of small-scale confined flows, nonlinear dynamics, thermal phenomena at liquid/solid interfaces, micropropulsion characteristics based on free surface flows, and various aspects of self-similarity and pattern formation within these systems. Troian's work combines theoretical analysis, numerical simulations, and experimental methodologies to explore fundamental principles for engineering applications. Her current projects examine cusp formation in thermally and electrically driven films, nanofluidic behaviors, and advanced lithographic techniques for nanofilms. Troian is actively engaged in the study of pioneering techniques such as non-contact lithography and the dynamics of Marangoni wave phenomena in biophysical contexts.
