Dr. Michael Head


Mike founded Precision Measurement Engineering out of his garage in 1982, while completing his Ph.D at Scripps Institution of Oceanography in San Diego. The innovative micro-scale sensor he developed allowed researchers to track very small fluctuations of temperature and conductivity in water samples. Mike still works on research and development for PME, while his daughter leads the company.
