Jhanis J. Gonzalez is Technical Director for Product R&D and Management at Applied Spectra, Inc. After receiving Dr. a BS in Chemistry and then PhD in Physics-Chemistry from the Universidad Central de Venezuela, Dr. Gonzalez joined the US-DOE Lawrence Berkeley National Laboratory, where he presently serves as a Principal Scientific Engineering Associate. His research focuses on understanding mechanisms of laser-material interactions (ablation) using nanosecond and femtosecond pulsed lasers and their impacts on LIBS, LAMIS, and all platforms of ICP-MS/OES systems. He is also involved in developing data analysis software and analytical methods for bio-imaging, energy, environmental, geochemistry, biological, and metallurgy industries. Dr. Gonzalez has authored/co-authored almost 100 peer-reviewed scientific publications and professional meeting abstracts on different (H-index = 29) that have received more than 2900 citations.

Dr. Jhanis J. Gonzalez C. obtained his Ph.D. degree in Chemistry (Physics-Chemistry) from the Universidad Central de Venezuela in 2002. He started his scientific career as a visiting scientist and postdoc researcher at Lawrence Berkeley National Laboratory (USA). Currently holds two positions, one as a Technical Director, Product R&D, and Management at Applied Spectra, Inc. and also as a Principal Scientific Engineering Associate at Lawrence Berkeley National Laboratory, Berkeley, CA. His research focuses on understanding mechanisms of laser-material interactions (ablation) using nanosecond and femtosecond pulsed lasers and their impacts on LIBS, LAMIS, and all platforms of ICP-MS/OES
systems. He is also involved in developing data analysis software and analytical methods for bio-imaging, energy, environmental, geochemistry, biological, and metallurgy industries. Dr. Gonzalez has over 70 manuscripts published in peer review journals, more than 70 presentations, and invited lectures at national and international conferences.
