Aakash Ahamed
Staff, Department of Geophysics - Knight Program
Research Assistant, Geophysics Faculty ProgramsBioAakash Ahamed (BS, with honors, Franklin and Marshall College; MSc, Boston College; PhD, Stanford University) is a hydrologist developing scientific methods for satellite and airborne remote sensing measurements with applications to water resources, natural hazards, and agricultural systems. His doctoral work focused on developing satellite-based models of groundwater mass changes in California's aquifers. Aakash previously worked as a support scientist in the Hydrological Sciences Lab at NASA Goddard Space Flight Center, where he constructed satellite-based models of flood and landslide hazards. He has also developed remote sensing analyses and software at Ceres Imaging, a successful precision agriculture start up based in Silicon Valley, and interned as a GIS analyst at the World Wildlife Fund for Nature in Washington, DC.

Sarfaraz Alam
Postdoctoral Scholar, Geophysics
BioSarfaraz Alam is a Postdoctoral Scholar at Stanford University, where he is modeling nitrate transport in groundwater and surface water to improve approaches to enforcement. His research integrates hydrologic modeling, contaminant transport, remote sensing, and data science to understand how climate and human-induced changes affect water resources and the environment. Sarfaraz earned his Ph.D. in Civil Engineering from UCLA in 2021.
Sarfaraz received an Outstanding Ph.D. student award, Dissertation Year Fellowship, and Graduate Division Fellowship at UCLA. He authored nine peer-reviewed journal articles and presented his research in over ten international conferences. -

My students and I devise new algorithms to improve the imaging of reflection seismic data. Images obtained from seismic data are the main source of information on the structural and stratigraphic complexities in Earth's subsurface. These images are constructed by processing seismic wavefields recorded at the surface of Earth and generated by either active-source experiments (reflection data), or by far-away earthquakes (teleseismic data). The high-resolution and fidelity of 3-D reflection-seismic images enables oil companies to drill with high accuracy for hydrocarbon reservoirs that are buried under two kilometers of water and up to 15 kilometers of sediments and hard rock. To achieve this technological feat, the recorded data must be processed employing advanced mathematical algorithms that harness the power of huge computational resources. To demonstrate the advantages of our new methods, we process 3D field data on our parallel cluster running several hundreds of processors.
Teaching
I teach a course on seismic imaging for graduate students in geophysics and in the other departments of the School of Earth Sciences. I run a research graduate seminar every quarter of the year. This year I will be teaching a one-day short course in 30 cities around the world as the SEG/EAGE Distinguished Instructor Short Course, the most important educational outreach program of these two societies.
