My primary research interest is in the field of development and applications of various
aspects of computational seismology including seismic modeling, inversion, and the
use of artificial intelligence to solve practical geophysical inverse problems.
Although the use of alternate energy resources are in place, to meet the rising energy
demands, it is expected that the fossil-fuels will remain to be the major energy supplier
in the coming decades. Consequently, to mitigate global warming caused from fossil-fuel
consumptions and attain a carbon-neutral future, carbon capture utilization and storage
(CCUS) is important. One major component of CCUS is carbon sequestration, where time-lapse
monitoring of the sequestered gases to ensure containment of the injected fluids is
essential. Using state-of-the-art waveform-based inversion tools to monitor the carbon
sequestered reservoirs has been one of my research interests over the past ten years.
Besides CCUS, natural hazards caused from climate change in now a challenging issue.
Recently, I have been interested in studying how geoscience can help in handling this
challenge. By accurately estimating ocean-water sound-speeds from marine seismic
data and mapping them onto temperature and salinity, I have been collaborating with
the atmospheric scientists in developing future climate models in which seismic data
will be one major component. Additionally, characterizing the methane hydrates, and
analyzing earthquake-related geohazards are some of my other research interests.

I strongly believe that good teaching challenges a student’s mind, allowing it to grow and develop. I also believe in teaching that goes beyond standard classroom lectures and provides students with hands-on experience with solving practical problems. I currently teach a graduate-level course on geophysical optimization theory that combines classroom lectures with hands-on exercises to solve practical problems. In addition, I also teach an undergraduate course on Petroleum Geology where I try to share my personal experiences in the oil and gas industry with the students.
