Jose AndradeJason Marshall
Postdoctoral Scholar in Mechanical and Civil Engineering

My research is focused on the multi-scale, multi-physics simulation of geomaterials.  Specifically, I am working on developing a computational framework to enable many types of multi-physics simulations to be performed within a single high performance computing Discrete Element Method (DEM) code.  My background is in the computational mechanics field with a BS from Cal Poly - SLO and a PhD from Carnegie Mellon University.

Jose AndradeShahrzad Roshankhah
Postdoctoral Scholar in Mechanical and Civil Engineering

My research is focused on modeling how the physical properties of geomaterials change upon heat and mass extraction or injection in subsurface area. Involved processes and material responses include multi-physics (hydro-thermo-chemo-mechanical), multi-phase (solid, gas, and liquid), and multi-scale (soil and rock grain scale to oil reservoir scale) phenomena that need to be better understood for improved efficiency and longer reliability of energy and environmental infrastructures.
I completed my PhD at the Georgia Institute of Technology in 2015. Now, as a post-doctoral scholar at the California Institute of Technology, I am modeling the effect of hydraulic fracturing on the evolution of mechanical and hydraulic properties of rocks, especially shales.

Xilin Lu
Visiting Associate in Mechanical and Civil Engineering

My research is focused on the constitutive modeling, instability, and failure of geomaterials; slope and underground excavation stabilities; long-term settlement of soft subgrade. I completed my PhD at Tongji University in 2009. Now, I am an Associate Professor at the Department of Geotechnical Engineering of Tongji University. Currently at Caltech, as an visiting associate at Professor Andrade's group, my research focuses on the initiation and evolution of instability in granular material and their applications in geotechnical problems.

My research interests include developing new methods and techniques to characterize and simulate granular materials at the grain scale.  In particular, my research focuses on a Discrete Element Method (DEM) variant that has the ability to capture particle shape and integrate our computations with experimental images and data.
Before I entered Caltech, I grew up in Hawaii, then attended the University of Southern California, graduating in 2012 with a BS in civil engineering.  Outside of school, my hobbies include surfing, soccer, and video games.

Eloïse Marteau

I got my B.S. and M.S. in Civil Engineering from Ecole Polytechnique Federale de Lausanne (EPFL), in Switzerland. After visiting Caltech for 6 months during my Master’s thesis, I joined Prof. Andrade’s group at Caltech for my Ph.D. in September 2012. My research focuses on understanding the micromechanics of critical state in granular media. During my spare time, I like doing synchronized swimming, traveling, and cooking.

I got my B.S. in Civil Engineering at Tongji University Shanghai, China. I am pursing my Ph.D. in Applied Mechanics in Dr. Andrade's group. My research focuses on incorporating grain morphology effect into the rheology of dense granular flows with special interest in the solid-liquid transition through both numerical simulation in the grain scale and experiment investigation. Outside of research life I enjoy swimming,jogging and traveling.

I received my B.S. from the National Technical University of Athens, Greece and my M.S. from the University of California, Davis both in Civil Engineering. I am currently pursuing my PhD in Applied Mechanics in Prof. Andrade's group. My research focuses on modelingreduced-gravity effects in granular media across different scales and phases (solid-liquid) through both discrete and continuum frameworks. In my spare time, I enjoy climbing, hiking and cooking.
