Ifeoma Anyansi , Graduate Student

Ifeoma Anyansi is currently a graduate student within the Computational and Mathematical Engineering department at Stanford University. Her research is at the intersection of machine learning, policy, and climate change.  She is drawn to the capacity of data science to spur community resilience in the face of storm surges, tsunamis, and sea level rise. By focusing on vulnerable populations, her research goal is to model the differential impact that coastal hazards will have in the upcoming century. This work is done in collaboration with Stanford’s Natural Capital Project.
She received her B.S. at Duke University in Civil and Environmental Engineering. Before attending graduate school, she served as a policy intern within the Office of The Chief Federal Sustainability Officer where she contributed to the adoption of sustainable practices at the federal level. Her personal interests include playing the piano, youth outreach, and diversity and representation in academia.


Cansu Culha

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.

 


Indraneel Kasmalkar , Graduate Student

 

Neel is a PhD student at the Institute of Computational and Mathematical Engineering (ICME). He graduated from the University of California, Berkeley with a B.A. in Mathematics. At SIGMA, Neel uses computational models to study the processes happening at the bed of a glacier and how they affect ice flow. In particular, his focus is on understanding the multi-phase interactions between the ice, the subglacial water channels and the underlying sediment layer.

 


Tobias Keller , Post Doctoral Scholar

 

Tobias Keller research aims at furthering the understanding of the physics of magmatic and volcanic systems. He pursues that goal by expanding available models for multi-component multi-phase flow in geodynamics, and by developing the next generation of magma dynamics simulation software. His current research is focused on understanding how the three-phase interaction between crystals, melt and vapor in subvolcanic magma bodies controls volcanic activity as observed on the surface.

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. 

 


Sergio Maldonado

Sergio joined the group in January 2016 after completing his PhD in Environmental Fluid Mechanics at the University of Edinburgh (UK). His doctoral thesis explored the development of mathematical models to study sediment transport and bed morphological evolution in open channels. Sergio also holds a M.S. in Coastal Engineering from Universidad Nacional Autónoma de México (UNAM) and a B.Eng in Mechanical Engineering from Tecnológico de Monterrey (ITESM, Mexico). At Stanford, he works with The Natural Capital Project on the development and enhancement of numerical models aimed at quantifying the protective service provided by coastal ecosystems. His main goal is to investigate, through numerical and analytical means, the interaction between hydrodynamics, vegetation and sediment transport in the near-shore area.

 


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

Simone 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.

Simone received his 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.

His 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, Simone applies these methods to simulate tsunami-induced inundation and understand the role of coastal features in the mitigation of tsunami impacts.

He enjoy scientific writing, traveling and cooking with his wife, and spending time with their cat.


Zhipeng Qin

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.

 


Adrian Santiago , Graduate Student

Adrian Santiago is pursuing a Ph.D. in Geophysics and an M.S. in Environmental Fluid Mechanics in the Civil Engineering department. He holds a B.S. in Civil Engineering from Virginia Tech, where he started using numerical models. Adrian grew up below sea level in the Netherlands, where he became inspired by the Dutch approach to coastal engineering. His research at Stanford will look at nature-based solutions to various coastal hazards, and will often be in collaboration with the Natural Capital Project. In the long-term, Adrian hopes to develop and implement sustainable solutions to sea level rise adaptation - inspired by work done in the Netherlands but adapted to American society.


Zihan Wei , Graduate Student

Zihan is a PhD student in Geophysics. He completed BS degree in geology at Peking University, where he did research on simulating thermal interactions between oil reservoirs and intrusive magma. In SIGMA, Zihan studies multi-phase flow in volcano conduit. Specifically, his research interest is on understanding the stability of core-annular flow and the behaviors of bubbles and crystals by combining the results of geochemical studies and computational flow dynamics.
