Work Experience
Southwest Research Institute,
San Antonio, TX
2017 - 2021
Developed advanced electromagnetic nondestructive testing techniques to address clients applications:
Residual stress measurement in aluminum structures using innovative eddy current techniques; applications include cold-worked holes and heat affected zone in welds;
Low frequency eddy current detection of second-layer fatigue cracks around fastener holes containing aluminum alloy or Inconel bushing;
Eddy current detection of second-layer cracks around martensitic steel bushing using magnetic saturation techniques;
Evaluating the effects of machining parameters on the surface quality and geometrical imperfection of Inconel bushing using eddy current rotational probes;
High-resolution eddy current techniques for quality control of additively manufactured parts – mapping surface roughness, detecting porosity and material defects;
Detection of grinding induced thermal damage of ferromagnetic material in finish ground parts using eddy current probes;
Electromagnetic modeling of NDE problems using CIVA software.
Cummins Allison,
Carlsbad, CA
2015-2017
Developed theoretical models for eddy current sensors used in coin recognition and authentication;
Provided expertise in pulsed eddy current, multi-frequency eddy current techniques.
Albany Instruments Inc.,
Charlotte, NC
2001 - 2015
Designed novel eddy current testing systems, based on giant magnetoresistive (GMR) sensor technology, with enhanced capability to detect hidden defects in metallic structures;
Developed prototypes of eddy current instruments, including original GMR probes, probe arrays, hardware for signal conditioning, developed software for data acquisition and display;
Tested and real-time imaging of samples relevant to the aerospace industry - such as riveted aircraft lap joint structures - and to the nuclear power plants - heat exchanger tubing, welds;
Managed several R&D projects including three Small Business Innovation Research contracts;
Wrote proposals to obtain grants from industry and federal government agencies, preparing technical reports and Powerpoint presentations.
