Summary

Mohamed Ebaid is currently a Postdoctoral Fellow in The Cooper Lab at JCAP-LBNL. He earned a PhD in Physics from Chonnam National University in 2015. His research is mainly focusing on the cost-effective synthesis and in-situ characterization of emerging nanomaterials for applications in solar hydrogen generation, CO2 reduction, thin-film technologies, and optoelectronic devices. He has extensive hands-on experience in nanomaterials synthesis, clean-room processing, electrochemical measurements, FIB/TEM microstructure measurements, and in-situ XRD/Raman characterizations. He also has deep understanding of design-of-experiments and data analysis as well as instrumentation design, troubleshooting, and maintenance. Mohamed has a strong track-record in cutting-edge research with four patent applications and over 50 technical journal publications and conference presentations.
