John Jaszczak has had an interest in collecting minerals since approximately age 4, but became a serious mineral collector at age 13. He earned a B.S. in Physics from Case Western Reserve University in Cleveland, Ohio and subsequently earned M.S. and Ph.D. degrees in Physics from The Ohio State University where he studied crystal surface roughening and quasicrystals. After conducting computational research in materials physics for two years at Argonne National Laboratory, he joined the physics department at Michigan Technological University where he now serves as Professor of Physics. He became Adjunct Curator at the university's A. E. Seaman Mineral Museum in 1992. He also is adjunct professor in the departments of Cognitive and Learning Sciences, and Materials Science and Engineering. He currently serves as associate director for education and outreach in the university's Multiscale Technologies Institute.
