Kali Allison
Kali is studying the conditions of a volcano's magma chamber prior to eruption using physics-based simulations.
Cansu Culha , Graduate Student
Cansu Culha completed BA degree in geophysics at University of California, Berkeley.
There she studied the active morphologies on Jupiter's moon, Europa's, surface. She
is stimulated by the creativity required to solve problems with minimal data.
In SIGMA, she is interested in studying volcanoes and crustal deformations
through the application of multiphase fluid dynamics. Her current work investigates
how crystals in magma chambers can govern what is observed on the surface.
Cooper Elsworth , Graduate Student
Cooper is a PhD student in the Department of Geophysics studying streaming ice flow in Antarctica. He joined the group from Penn State University, where he completed BS and MS degrees in Engineering Mechanics, focusing on computational methods for fluid-structure interaction. His research interests include coupled systems, fluid dynamics, glaciology and computational mechanics. In SIGMA, Cooper studies the stability and dynamics of ice streams, specifically those on the Siple Coast of West Antarctica.
Brent Lunghino
Brent Lunghino is a graduate student in the Computational Geosciences MS program. He holds a BS in Geological Sciences from Brown University. Brent joined Stanford after working as a research assistant at the US Geological Survey's Pacific Coastal and Marine Science Center where he studied tsunami hazards through sedimentology. His research interests are centered on using numerical simulation to understand physical processes in coastal systems, including modeling 3D interactions between flows and obstacles. In SIGMA, Brent is working on numerical models of tsunami hydrodynamics and sediment transport to inform engineering of coastal protection in regions threatened by tsunamis.
Tracy Mandel , Tracy Mandel
Tracy Mandel is a PhD candidate in the Civil and Environmental Engineering department, where she is a member of the Bob and Norma Street Environmental Fluid Mechanics Laboratory. Her research focuses on improving our physical understanding of how near-shore vegetation protects the coast from flooding and erosion. She studies the hydrodynamics of fluid-vegetation interaction through careful laboratory experimentation as a collaborator with the computational SIGMA group.
Simone Marras , Research Associate
I joined the Dept. of Geophysics at Stanford after 2 years as a National Research Council research associate
in the group of Prof. Francis Giraldo at the Dept. of Applied Mathematics of the Naval Postgraduate School in Monterey, California.
I received my doctoral degree in environmental engineering and scientific computing (numerical weather prediction)
from Universitat Politècnica de Catalunya (Spain) supervised by Dr. Oriol Jorba and Dr. Mariano Vázquez at the Barcelona Supercomputing Center.
My thesis and post-doctoral work mainly focused on the analysis and definition of dynamic diffusion schemes
for the stabilization of Finite Elements, Spectral Elements, and Discontinuous Galerkin methods on the one hand and large eddy simulation on the other.
At Stanford, I apply these methods to simulate tsunami-induced inundation and understand the role of coastal features in the mitigation of tsunami impacts.
I enjoy scientific writing, traveling and cooking with my wife, and spending time with our cat.
Zhipeng Qin , Post Doc Scholar
Before joining Stanford in June 2015, Zhipeng Qin held a
position as research assistant in Prof. Amir Riaz's CFD group at University of
Maryland, and received his doctoral degree in the department of Mechanical
Engineering. His doctoral dissertation investigated numerical simulation for
multiphase flow, and was mainly focused on the development of interface
advection schemes and jump condition capturing methods.
At SIGMA, the goal of Zhipeng's research is to advance
the basic understanding and predictive capabilities of complex multi-phase
flows in geyser and lava lake. He is pursuing this goal by applying
computational methods for the solver of Navier-Stokes equation with high
viscous difference.
