Babak Shafei, Ph.D.

Babak Shafei, is the founder and CEO of AquaNRG, an environmental and energy tech company headquartered in Houston, Texas. Under his leadership, AquaNRG has raised $1.4M seed fund through 3 Small Business Innovation Research (SBIR) grants from the US Department of Energy and National Science Foundation. 

He has more than 15 years of experience consulting major exploration and production companies to design and optimize energy production while mitigating the environmental footprint of their operations in conventional and unconventional plays. 

Babak holds Ph.D. in earth and environmental sciences from Georgia Institute of Technology where his Ph.D. thesis on multiscale reactive transport modeling received “Research Excellence Award”. In 2007, he received a prestigious Marie Curie fellowship from the European Commission which provided a unique opportunity for him to work on global water resources contamination and remediation strategies at Utrecht University in the Netherlands and ETH Zurich in Switzerland.
