Dr. John Gibson
John Gibson is currently a Senior Scientist in the Chemical Sciences Division of Lawrence Berkeley National Laboratory (LBNL). After receiving his BA in Chemistry (summa cum laude) from Boston University in 1979 and PhD in Physical Chemistry from the University of California, Berkeley in 1983, he joined the scientific staff of the Chemical Sciences Division of Oak Ridge National Laboratory (ORNL). At ORNL he explored chemistry of 11 of the 14 actinide elements, from thorium through fermium. His research emphasis there was on gas-phase actinide ion-molecule reactions to explore the distinctive chemistry of the 5f elements. In 2007, after 24 years at ORNL, he relocated to LBNL as a Sr. Scientist and Principal Investigator. At LBNL he has developed a unique electrospray ionization quadrupole ion trap mass spectrometry (ESI-QIT/MS) capability to further explore gas-phase f-element chemistry, with an emphasis on elucidating fundamental aspects of actinide ion complexation. The results furthermore provide a basis to evaluate and develop advanced computational methodologies for heavy elements. During the past decade, gas-phase ion chemistry of the actinides from Th through Cf has been studied at LBNL. The LBNL ESI-QIT/MS capability is now being employed in CAST to advance understanding of lanthanide and actinide coordination chemistry, with an overarching goal of providing a basis to develop advanced separations techniques. Gibson actively collaborates with many domestic and international scientists, both experimentalists and theoreticians. He has published some 170 peer-reviewed journal articles in the course of 34 years of heavy element research at ORNL and LBNL.
