Prior to my appointment at Duquesne University, I held a postdoctoral appointment at Oklahoma State University. I also held visiting positions at Universitӓt des Saarlandes, Saarbrücken, University of California, Berkeley and Carnegie Mellon University.

My field of expertise is experimental condensed matter physics, where it meets with Materials Science. I am interested in investigations of the structure-property relationships relevant to rational construction of new magnetic materials. For this purpose I use laser pulses and particle beams to obtain amorphous and nanocrystalline magnetic materials with controlled properties, such as controlled magnetic anisotropy. I also investigate mixed oxide nanoparticles to document the onset of solid solutions by mechanochemical activation at the nanoparticle scale. Most recently, I investigated the behavior of graphene during milling with ferrite nanoparticles. The investigation techniques that I use are Mӧssbauer spectroscopy, magnetic measurements, X-ray diffraction, electron microscopy and thermal analysis. These can be observed in my latest book, "Recent applications of the Mӧssbauer effect", published by Dorrance Publishing Company (2020).

The funding received from the National Science Foundation, Department of Energy, Petroleum Research Fund and Research Corporation made it possible to mentor over 30 students and 3 postdoctoral researchers.
