Dr. John Bradshaw

Education

University of Pittsburgh, Ph.D. in Physics, 1989
Lehigh University, M.S. in Physics, 1984
Lehigh University, B.S. in Engineering Physics, 1982

Teaching

Introductory Physics, PHYS 111 & 112

Physics Laboratory, PHYS 121 & 122

Research

The primary focus of my research is mid-infrared materials and technologies, with an emphasis on applications to mid-infrared sources and sensors, particularly chemical sensing of hydrocarbons and air-quality measurements related to natural gas exploration and extraction. Currently, I am pursuing several projects:

  • Air quality measurements in the vicinity of the natural gas extraction sites at Beaver Run Reservoir, Westmoreland County
  • An external-cavity tunable diode laser for simultaneous measurements of methane, ethane, and other hydrocarbons in the 3.3-3.4 micron wavelength region
  • Synthesis and measurement of the electronic properties of HgSe and HgTe nanoparticles

Accomplishments

After a National Research Council Associateship at a U.S. Army Laboratory, Dr. Bradshaw became a staff physicist at what is now the U.S. Army Research Laboratory (ARL) in Adelphi, Maryland and stayed in that position for ten years. In 2001, he and four colleagues co-founded Maxion Technologies, Inc., to develop mid-infrared semiconductor lasers for commercial, government, and research applications. At Maxion, Dr. Bradshaw served as VP of Product Development from 2001 through 2009 and as a Senior Principal Research Scientist from 2009 through 2012. Maxion was acquired by Physical Sciences Inc. in September 2009 and by Thorlabs in November 2012. Dr. Bradshaw joined the Physics Department at IUP in August 2012.
