Steve L. Allman is a research assistant in the Biological and Nanoscale Systems Group. He has more than thirty years of laboratory experience in development of ultra-sensitive atomic and molecular detection techniques based on laser spectroscopy and mass spectrometry.  More recently, he has been involved in flow cytometry and developing new technology for aerosol science and microbial biology applications.
Currently he is participating in projects involving:

  • isolation of novel environmental microbes through cell sorting flow cytometry
  • use of cell sorting flow cytometry for microbial genomics
  • microbial sorting and characterization on microfluidic platforms
  • impurity detection in solid materials using laser-induced breakdown spectroscopy
  • measurement and characterization of atmospheric particulates
  • development of new technology for inhibition of medically relevant bacterial biofilms

Steve also serves as Laser Safety Officer for the Energy and Environmental Sciences Directorate.
