Hi there! My name is Mohammed Ombadi, and I’m a postdoctoral researcher at Lawrence Berkeley National Laboratory. I obtained my Ph.D. and M.Sc. degrees in Civil & Environmental Engineering from University of California Irvine. My research interests lies at the intersection of hydrology, climate sciences and data science. In particular, I'm interested in utilizing recent advances in data sciences and big data analytics to improve our mechanistic and predictive understanding of climate change impacts on the hydrologic cycle.  

Currently, I examine the impact of hydrological extremes and disturbances (e.g., floods and droughts) on water quality using data-driven approaches as part of the iNAIADs project. I also study the detection and attribution of climatic extremes in observational records as part of the CASCADE project.

Featured Publications


Dec 12 - 16, 2022 [Conference Presentations]

In this year's American Geophysical Union (AGU) Fall Meeting 2022, plan to stop by to check my presentations and secessions: 1) I'm a primary convener of a session on causal inference in hydrology; 2) Oral presentation on temperature volatility extreme events; and 3) Poster presentation on floods and impacts on water quality.

I represented Berkeley Lab, together with two talented postdocs, in the Bay Area Research SLAM (a competition across four national labs: Lawrence Berkeley National Lab, Lawrence Livermore National Lab, SLAC National Lab and Sandia National Labs.

Did you know that temperature can change by more than 15 degrees Celsius from one day to another? In my recent paper published in Weather and Climate Extremes (with my o-author Mark Risser), we analyze day-to-day temperature changes across the US, and we show that extreme changes have been increasing over the past 7 decades over Central and Eastern parts of the US.
