Dr. Siewick has been a Chief Scientist at Alion Science and Technology Corporation since 2005. He left academia after
defending his dissertation to begin a lengthy career developing novel sensing technology, sensors and sensing systems,
mostly for military purposes. He is the inventor of the reactance-bridge-based Alion Magnetic Effects Sensor that
on the changes in the impedance of a sensing coil over a range of AC frequencies to sense objects permeated by the
of the coil. His theoretical efforts over the past four decades are directed at the fundamentals of physics that forms
the basis for relativity and quantum mechanics.
