Biography

Nils Hansen, the Principal Investigator of the Flame Chemistry and Diagnostics Laboratory at the Combustion Research Facility has long specialized in the development of the tools to elucidate the chemistry occurring in flames. As organizer of the international Workshop on Flame Chemistry series, he has been an important part of the validation efforts of chemically accurate models, and regularly hosts international collaborators. Spanning the range from ignition chemistry to the chemistry of soot and aromatic precursors, Dr. Hansen uses a highly sensitive molecular beam mass spectrometer and a tandem mass spectrometer to reveal important chemical pathways. As a facility scientist, he adapts these tools for use in plasma systems where they would provide much-needed validation of plasma chemistry reaction sets.

Research Interests

Interrogation of chemistries in reactive environments using high-resolution mass spectroscopy.

Education

Nils Hansen received his PhD in Physical Chemistry at the Christian-Albrechts-University of Kiel, Germany, under the guidance of Prof. F. Temps. Before joining Sandia, Nils worked with Prof. A. M. Wodtke as a postdoctoral researcher at the University of California, Santa Barbara, and as a staff member at the BASF AG, Ludwigshafen, Germany.
