• Provide technical leadership and innovative solutions for resonator and sensor devices.• Advise and support device fabrication processing for R&D and programmatic initiatives.• Manage five sputter deposition systems in a class 10 cleanroom to develop deposition processes.• Exhibit a consistent ability to secure project funding through successful proposals.

• Advise and support device fabrication processing for R&D programs.• Developed deposition processes for RF piezoelectric resonators.

Raleigh-Durham, North Carolina Area

• Created a Markov Chain Monte Carlo (MCMC) routine to conduct Bayesian inference on X-ray diffraction (XRD) data that is quantified via line-profile analysis. This routine generates a better description of errors than what is available from least squares analysis.• Integrated the MCMC routine into LIPRAS, a least squares peak fitting software.

Raleigh-Durham, North Carolina Area

• Specialized in X-ray diffraction (XRD) techniques, attended numerous synchrotron experiments.• Created MATLAB and Python scripts to analyze and view diffraction data as well as read data files for further manipulation.• Analyzed ~45 GB of XRD data, through multiple software and MATLAB scripts.• Quantified strain and texture changes as a function of electric field in bulk and thin film ferroelectrics.• Elucidated the role of mechanical constraint and texture on domain reorientation in PZT films.• Determined that the stiffness of the underlying material stack impacts the extrinsic response of released PZT films used in microelectromechanical systems.• Studied the effects of electrical and mechanical loading on the domain and phase behavior of PZT multi-layered piezoelectric actuators.• 20 peer reviewed publications in: Acta. Mater., J. Amer. Cer. Soc, and Adv. Funct. Mater. Achieved by completing over 20 successful APS experiments and traveling internationally to work with collaborators..Advanced Photon Source at Argonne National Laboratory• Active user from 2012-2017, attended over 22 experiments• Generated scripts to automate experiments to facilitate data collection and minimize human error.• Wrote proposals to obtain beamtime to conduct in situ experiments of powders, bulk, and thin films with applied electric field, stress, or temperature.• High energy XRD beamline-In situ electric field XRD measurements of bulk and thin film ferroelectrics.• Nanodiffraction beamline- microdiffraction of ferroelectric thin films as a function of voltage.• High resolution powder diffraction beamline- XRD temperature measurements of powder ferroelectrics.

Arizona State University

• Monitor usage of liquid nitrogen, chemicals, and gases used by facility. Documented and reported any problems or trends tools may experience that could potentially lead to equipment failure.• Promotion from Lab Aide to Member of Nanofab Process Development Team.• Operated various research tools in the cleanroom’s metrology and lithography suites in order to train students and faculty as well as carry out service requests.• Trained users on Field Emission Scanning Electron Microscopy (FESEM) and X-Ray microanalysis as well as perform service request using these tools to analyze and image samples.

Pennsylvania State University

• Project Title: Time-Resolved Study of Anisotropic Nanostructure Growth Using Integrated Droplet-Based Microfluidics and X-Ray Absorption Spectroscopy.• Successfully created a microfluidic device in order to synthesize gold nanoparticles within the device.• Participated in REU symposium at Penn State University (PSU) and presented results at Georgia Tech.
