• Contributes to a research program investigating anti-thermal behavior of materials funded by the W.M. Keck Foundation
• Leads two collaborations with the Army Research Laboratory that focus on nanocrystalline thermal stability and characterization, and low-density boron carbide armor ceramics
• Mentors graduate and undergraduate students to aid in their research and professional development

Bethlehem, PA

• Dissertation: Investigating the Thermal and Phase Stability of Nanocrystalline Ni-W Produced by Electrodeposition, Sputtering, and Mechanical AlloyingAdvisor: Dr. Martin P. Harmer
• Critiqued solute segregation, chemical ordering, reduced atomic diffusivity, and impurity solute particle drag as potential thermal stability mechanisms
• Revealed that phase stability and the type and amount of impurities incorporated during bulk fabrication processing strongly influence nanocrystalline thermal stability
• Applied focused ion beam and aberration-corrected scanning transmission electron microscopy to survey nanocrystalline Ni-W on the atomic-scale
• Collaborated with research partners at the University of California – San Diego, Carnegie Mellon University, and the Army Research Laboratory
• Tracked the microstructural evolution of Ti-5Al-5Mo-5V-3Cr alloys that were subjected to post-weld heat treatments after electron-beam welding with aberration-corrected scanning transmission electron microscopy and.

Materials Science And Engineering

Continued the development of a kaolinite-based sintering and densification class project in the second and third years of the program by adding metallographic preparation and mechanical testing. Graded and provided feedback for quizzes, research updates, and semester term paper.

Materials Science And Engineering

Adapted labs utilized during the Lehigh Microscopy School for undergraduate use to teach modern microscopy techniques to undergraduate students.

Gaithersburg, MD

• Dissected commercially available composite baseball bats to search for reinforcing carbon nanotubes that may potentially harm consumers upon failure
• Employed Raman spectroscopy, focused ion beam microscopy, and scanning electron microscopy to determine that the nanotubes were located in the polymer epoxy surrounding carbon fibers

Laurel, MD

• Compared film thickness determination techniques to determine the coating thickness of gold and nickel overlayers on brass microelectronic circuit components
• Recognized that X-Ray Fluorescence exhibited the best combination of efficiency and accuracy compared to light optical microscopy, scanning electron microscopy, and transmission electron microscopy techniques.
