Photonics Industries International Inc. NOV ’06 – FEB ‘09

Product Manager DM Series (AUG ’07 – FEB ‘09)

Responsible for the day-to-day operations of a $4.3M product line, overseeing a group of six scientists, engineers and technicians responsible for all phases of research, design and production.

•Audited existing processes, identified critical gaps and designed new corrective procedures. Authored new work procedures and trained staff for improved productivity and safety.

•Implemented Quality improvement program including spot audits, root-cause analysis, and implementation of remedial actions.

•Handled customer complaints including physically visiting customer plants and collaborating with production engineers to identify and solve issues. Demonstrated exemplary customer service strengths in oral and written communications.

•Facilitated numerous Root Cause Failure Analysis Investigations in regard to product and/or system failures.

•Produced short/long term production scheduling, forecasting, monthly analysis, and cost forecasting.

Key Accomplishments:

•Solved significant design flaws in the cooling systems that were resulting in customer complaints and product failures.

•Streamlined production procedures to reduce costs and increase production by 23%.

•Performed numerous domestic and international on-site visits for Demonstration, Integration and Customer Training. When needed provided on-site field service and repair to reduce “down-time” and restore customer confidence resulting in nearly a 30% increase in DM sales over 18 months.

Sr. Laser Engineer R&D (NOV ’06 – AUG ‘07)

R&D Group member responsibilities included new product development and product improvement initiatives for existing product(s) line. Experienced in taking products from concept to production.

New product developments include:

•EE494/594 - Consumer Optoelectronics

Research Assistant – Center for Advanced Electronic and Photonic Materials (CAPEM) and the Laboratory for Advanced Spectroscopic Evaluation (LASE) (2001 – 2003)

•Resolved the phase segregation of indium due to growth temperature in InGaN/GaN multiple quantum well heterostructures on a sapphire substrate.

•Resolved the spontaneous polarization of AlGaN resulting from the asymmetry in the tetrahedral sub-structure of the wurtzite lattice. This included performing CW and time-resolved photoluminescence experiments on quaternary AlInGaN/AlGaN quantum well materials, analyzing and modeling the data.

•Assisted in the acquisition of the lab formerly known as Optek located in Baltimore, MD. Primarily responsible for the market analysis of all equipment, tear down, transportation, and set-up of the facility in its current location on the campus of the State University of New York at Buffalo now known as CAPEM

•Responsible for two ultrafast laser laboratories one Spectra-Physics system the other a Coherent Inc. system which include: Ti-sapphire oscillator(s) and a regenerative amplifier pumped by a CW Ar+ laser as well as a visible and an infrared optical parametric amplifier and several frequency doubling and tripling setups.

Research Assistant - Laboratory for Advanced Spectroscopic Evaluation (LASE) (1998-2001)

•Resolved the presence of piezoelectric fields within p-i-n GaN/InGaN multiple quantum well structures. Specifically time integrated and time-resolved photoluminescence measurements and theoretical calculations of the effect of these fields; and how these fields influence the carrier dynamics and how the piezoelectric field will affect the design of GaN/InGaN devices.
