Charles W. Lewandowski is a graduate student in the Department of Physics.  In 2015, he received a Bachelor of Science in Mathematics and a Bachelor of Science in Physics from the University of Pittsburgh.  His current research consists of precision measurements of Newton's gravitational constant using magneto-gravitationally trapped microspheres.  He is also assisting on experiments to reach the quantum mechanical ground state of a harmonic oscillator using magneto-gravitationally trapped microspheres and testing theories of quantum gravity with this system.  His work consists of optics design, computational work, and vacuum and cryogenic system design and experiments.
