Steve L Allman

Distinguished Technician


Steve Allman has more than 40 years of experience providing laboratory research assistance at ORNL.  He has developed expertise in designing, assembling, operating, repairing and modifying wide-ranging equipment and facilities in support of research, including a 3MEV VanDeGraff accelerator, ultra-high vacuum systems, mass spectrometers, FTIR spectrometers, cell-sorting flow cytometer, aerosol science instrumentation, and a wide variety of research lasers.  He has helped design, construct and operate electronic, optical, and mechanical subsystems used in scores of experiments in wide-ranging areas of study involving state of the art technology, and assisted with data acquisition and analysis on numerous experimental projects.

Steve currently is collaborating in research efforts to elucidate the human oral microbiome and to develop more efficient medical radio-isotope generators. He also serves as Laser Safety Officer for the EES Directorate and Electrical Safety Officer for the Biosciences and Environmental Sciences Divisions.
