I did my undergraduate work at the University of Illinois at Urbana-Champaign (B.S. and B.A) from 1991-1996, and a year of graduate study at the University of Cambridge, UK (Churchill College) from 1996-1997.
During my graduate school years at Northwestern (1997-2001), my Ph.D. research (under the supervision of Prof. Seidman) focused on the nanoscale analysis of solute segregation at ceramic/metal interfaces (Ceramic/Metal Interfaces), and, more generally, on the study of early-stage phase separation and precipitation phenomena. Efforts were also directed towards the construction and commissioning of the Seidman Group three-dimensional atom-probe (3DAP, the predecessor to the lab's LEAP) and towards 3DAP data analysis (APEX).
After graduate school I worked in the Seidman Group as a Postdoctoral Fellow (2004-2005). I engaged in materials research related to improving the breakdown and dark current behavior of particle accelerator RF cavities. I oversaw upgrades to the lab's pulsed laser atom-probe (PLAP), and I was also involved in nanoscale materials research related to NUCAPT's newly-acquired (at the time) local-electrode atom-probe (LEAP). I was supervised jointly by Prof. Seidman and Dr. Jim Norem of Argonne National Lab.
From 2005-2006, I was a Staff Scientist in the Application Development and Engineering groups of Imago Scientific Instruments (Madison, WI; now a part of CAMECA, a Division of AMETEK, Inc.), where I worked on local electrode R&D, and on atom-probe application development (in particular, magnetic multilayer and semiconductor [Si-based] material applications).
I now (2006-present) work as the President at QuesTek Innovations (Evanston, IL), where I am a specialist in the fields of nanosturctural materials characterization and computational materials design. My work at QuesTek has focused on the development of high-strength steels for structural and gear applications, nickel superalloy development, high-strength/low-friction copper alloy development, advanced soft magnetic materials, advanced shape memory alloys, low-cost castable titanium alloys, and high-performance aluminum alloys. My work continues to be involved with advanced characterization techniques including LEAP atom-probe tomography and advanced serial-sectioning tomographic reconstruction analyses. I live in Chicago, IL with my wonderful wife Tania and my two kids (Sofia and Johnny).
