My research aims mainly at understanding better earthquakes, crustal deformation, and geomorphic processes.  
We use field observations, seismological and geodetic measurements, remote sensing to develop kinematic and dynamic models and inform theory.  Currently active projects concern: seismicity  and mountain building processes in the Himalaya; the imaging and dynamic analysis of seismic (‘regular earthquakes’) and aseismic (‘slow earthquakes’) fault slip; probabilistic forecasting of ground deformation and seismicity, in particular in the context of subsurface engineering operations (for CO2 storage or geothermal energy production for example; the effect of hydrology on crustal deformation and seismicity; ); dune dynamics on Mars and Earth

G. Bradford Jones Professor of Mechanical Engineering and Applied Physics; Investigator, Heritage Medical Research Institute

Professor Daraio focuses on materials science, condensed matter physics, and solid mechanics. Her lab is primarily interested in:

1. Developing a physical understanding of how stress propagates in nonlinear, ordered and disordered solid media at length scales ranging from nanometers to meters.

2. Studing the fundamental connections between structure and function in different physical domains (temperature sensitivity, electrical conductivity, etc.).

3. Exploiting this understanding for the creation of new materials and devices for engineering applications ranging from optomechanics to shock absorption.

To achieve these goals, her research takes advantage of nonlinearities in local material interactions (e.g., Hertzian contact interactions between particles or nonlinear interactions between nanostructures) to create novel systems and new materials with unprecedented global properties. These materials are composite systems in which typically basis elements that interact are arranged in well-defined geometries, such that the aggregate system as a whole exhibits properties that are not usually found in natural systems and can be exploited in engineering applications. Our work is primarily experimental, but it is informed by numerical and analytical studies, which serve as a guide in metamaterial construction and validation of their properties.

The Laboratory of Interfacial and Small Scale Transport {LIS2T} in the Department of Applied Physics and Materials Science at the California Institute of Technology specializes in both fundamental analysis and engineering design of micro/nanoscale fluidic systems. Of particular interest are small scale systems  dominated by large surface forces due to patterned capillary, van der Waals, Maxwell, thermocapillary and Marangoni fields. Theoretical analysis, numerical simulations (both continuum and molecular scale) and experimentation are all used to develop fundamental physical insight as well as robust design principles for application driven projects. Group focus is on formation, propagation, stability, coupling and control of nonlinear wave phenomena at the micro/nanoscale which induces rapid transport of mass, momentum and heat at moving interfaces. Systems of current theoretical interest include cusp formation in thermally and electrically driven thin films for super anti-reflecting coatings and space micropropulsion devices; nanofluidic phenomena involving Kapitza thermal jumps, layering transitions and thermal rectification in nanoscale devices; spatio-temporal parametric resonance and array formations in thin polymeric films exposed to large thermocapillary and Maxwell patterned fields; Lyapunov, modal and transient growth stability analyses of non-normal systems at zero Reynolds number; capillary and field enhanced propellant management systems for space micropropulsion applications; and solution of inverse problems for 3D lithographic patterning of nanofilms. Systems of current experimental interest include non-contact lithography of 3D micro-optical structures by patterned external fields; Marangoni wave phenomena and fractal wavefronts in biophysical systems; influence of layering transitions on slip behavior in nanoscale films; and optical wave propagation in structured polymeric waveguides.
