Siavash Khosh Sokhan Monfared
Postdoctoral Scholar in Mechanical and Civil Engineering
My current research focuses on multi-physics interactions of discrete particles. This includes exploring the physics of capillary and electro-magnetic interactions in granular systems with applications in bio-inspired mechanosensing and engineered entangled granular structures. I received my Ph.D. from MIT in civil engineering focusing on mechanics of heterogeneous porous solids and physics of confined fluids. Beyond research, I enjoy spending time outdoors.
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.
My research focuses on breakage at the grain scale for various granular media and how it affects the macro scale. I work to make predictions on the effects of breakage by developing new modeling techniques within discrete element modeling. Recently I have been using these new modeling techniques in collaboration with Jet Propulsion Laboratory (JPL) to model sample acquisition for missions to icy bodies in the Solar System. Before coming to Caltech, I got my BS in aerospace engineering at The University of Texas at Austin. Now I have switched to applied mechanics for my PhD here in California. Outside of school, I stay engaged in athletics and in leisure enjoy reading and gaming.
Robert Buarque de Macedo
I received my B.S. in physics from Carnegie Mellon University. I am currently pursuing a PhD in Applied Mechanics in the Computational Geomechanics group at Caltech. My general interest is in granular structures and the application of optimization techniques to models of granular materials. Outside of research I enjoy live music, yoga and playing guitar.
Rigoberto Moncada López
I obtained my B.S. in Civil Engineering at UNITEC, Honduras and received my master's degree in Civil-Geotechnical Engineering from Tohoku University, Japan. Currently, I am pursuing my Ph. D. in Civil Engineering at the Computational Geomechanics group from Caltech. My research interests include modeling of granular media and interaction with pore fluid, unsaturated granular response, stress state variation in granular materials and computational analysis of failure and shear banding. My prior research experience included granular erodibility, landslide mapping using GIS and remote sensing and slope stability.
Currently I am working on Discontinuum Modeling of Ice Sheets and Sea Ice, combining interparticle contact, thermal effects, particle breakage and fluid interaction.
During my free time I enjoy watching movies, jogging, eating out and traveling to new places.

I received my B.S. in Mechanical Engineering from University of Illinois Urbana-Champaign. I am currently pursuing my PhD in Prof. Andrade's group. My research focuses on the analysis of dynamic response of MDOF structures in computational and experimental methods. Outside of school, I enjoy hiking, doing road trips and gaming.
