Graduate Students

Kali Allison

Kali is studying the conditions of a volcano's magma chamber prior to eruption using physics-based simulations.


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.

Ian Avery Bick , Graduate Student

I’m a recent Stanford graduate with an M.S. in Environmental Engineering & Science at Stanford. Much of my recent work stems from involvement with the Sustainable Urban Systems program as an independent researcher and a teaching assistant where I applied geospatial data to study urban systems. I’m currently working within SIGMA to develop the open-source Stanford Urban Risk Framework in Python that addresses both direct economic damages and equity in sea level rise and coastal flood exposure.

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.


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 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.


Arnav Mariwala , Graduate Student

Arnav Mariwala is a coterminal masters student in Geophysics studying coastal risk. His research focuses on the applications of natural ecosystems, such as coral reefs, for mitigation of climate-driven coastal hazards. Arnav is passionate about using data science and fluid models to better understand how coastal communities can adapt to sea level rise and more frequent storms, and in doing so build a more sustainable and resilient future.

Arnav received his B.S. in Physics from Stanford University with a minor in History, and has interests in clean energy, policy, and entrepreneurship. He is currently one of the Co-Presidents of the Stanford Energy Club, Stanford’s largest energy and environment student group, and previously served as an editor at the Stanford Daily.

Alana Papula , Graduate Student

Alana Papula is a graduate student in the Applied Physics department. She works to develop basic theory tailored specifically to the systems studied in SIGMA, including ice sheets, permafrost, and volcanic systems.  Focuses include the behavior of ice sheets flowing or sliding on mixed till-rock beds, as well as determining the conditions that lead to different degassing mechanisms in saturated granular media. Alana received her BS in Physics from MIT, where her research focus was experimental particle physics and her study focus was statistical mechanics.

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.
