ACADEMIC AND PROFESSIONAL EXPERIENCE CREOL: College of Optics and Photonics, University of Central Florida, Orlando, FL Senior Research Scientist, 2011 – present (Bass Group: Dr. Michael Bass) • Managed experimental aspects of groups activities including design, implementation, and processing

data for reports, manuscript preparation, and professional meetings. • Performed extensive optical studies on titanium doped spinels, and other solid state samples. Studies

included absorption, fluorescence, luminescence lifetime, and laser emission studies. • Performed linear and nonlinear optical experiments on large core fibers to determine maximum bend

and transmittance losses at low and high fluences. Collaborated with modeling team to comprehend results and to acquire optimal results for dissemination to other researchers outside the immediate field.

• Worked with a modeling team to design a femtosecond seed fiber laser system for a commercial laser company. My most significant contributions were related to the nonlinear aspects of the program. Was responsible for a thorough laser characterization and quality test of one of the company’s femtosecond commercial seed laser options to determine its feasibility within their product line.

• Executed chemically cleaning processes and prepared polycrystalline and single crystal synthetic diamonds for optical absorption calorimetry, luminescence, and ellipsometry studies. Performed optical microscopy to determine\quantify micro-fractures and dark spots.

CREOL: College of Optics and Photonics, University of Central Florida, Orlando, FL Senior Research Scientist/Group Manager, 2004 – 2011 (NLO Group: Van Stryland and Hagan) • Prioritized the research group’s activities, including all aspects (experimentally-theoretically-

programmatically) of funded programs running in parallel (as many as five), to satisfy funded program’s responsibilities and deliverables while planning for anticipated non-funded programs.

• Conducted experimental and theoretical linear and nonlinear optical characterization of many classes of optical materials.

• Responsible for writing manuscripts and presentations for journals, conferences, proposals, and program reviews, with the ability to tailor each for the intended audience. Effectively communicated complex concepts and ideas to the intended audiences’ level of understanding.

• Wrote and implemented numerical models and simulations of light-matter interactions to extract linear and nonlinear optical parameters from experimental results.

Wake Forest University, Winston Salem, NC Post-Doctoral Research Associate, September 2003 to September 2004

Researched and characterized various nanomaterials and organics for organic electronic devices (OLEDs and OPVs) and their optical testing. Designed and set up the nonlinear optics lab from inception while prioritizing ongoing experiments without significant delay.

RESEARCH EXPERIENCE 2011 to present, I have been a Senior Research Scientist at the University of Central Florida in the College of Optics and Photonics (CREOL) and have been employed in Dr. Michael Bass’s group working on laser characterization and linear and nonlinear materials characterization. From 2004 to 2011, I was employed in the NLO group directed by Drs. Eric Van Stryland and David Hagan helping to manage their group and perform linear and nonlinear optical spectroscopy. From 2003 to 2004, I managed and maintained the optics facility in the Center for Nanotechnology and Molecular Materials at Wake Forest University under the direction of Dr. David L. Carroll where I performed my postdoctoral education. From September 2000 until 2003, I was responsible for managing and maintaining the optics division of the Center for Optical Materials Science and Engineering Technologies (COMSET) under the direction of Dr. John Ballato at Clemson University.

These positions have afforded me the opportunity to conduct a diverse array of projects from conception through design, implementation and completion into a product or publishable output. My research focus has been on the linear and nonlinear optical characterization and modeling of various optical materials (µ-conjugated and non-conjugated organics, wide/narrow gap semiconductors, glasses, plasmonic nanostructures, etc.) and the development and analysis of new experimental techniques (white light continuum generation for Z-scan and pump-probe and the double-pump probe technique for long-lived absorptions, etc.). My work within these research groups involved projects ranging from nanomaterials growth, scanning probe microscopy (AFM, SNOM, STM) and electron microscopy (SEM, TEM, EELS), to polymeric electro-optical device fabrication and testing (organic-LEDs (OLEDs) and organic-photovoltaics (OPVs), laser characterization, and various materials characterizations). This diverse variety of projects required frequent collaborations and provided a strong working knowledge of many experimental techniques and scientific disciplines.
