About

Research Engineer with 15+ years combined experience in instrumentation/software development, semiconductor device and material testing. I work as part of a team of scientists and engineers at Tyndall National Institute to provide services including electronic device and material characterisation for industry and research clients. As a NI Certified LabVIEW Developer I contribute to the training of scientific staff and students in the area of test and measurement automation. Daily activities include assessing customer requirements, review, development/implementation and reporting.

Past R&D focused on instrument development for optical astronomy at National University of Ireland Galway. Based around a Low Light level CCD detector from e2V, a high speed optical photometer (GUFI Mk I) was produced. This was used for the study of rapidly varying optical sources such as exoplanets and low mass stars. I was responsible for design (CAD), fabrication (electrical & optical components) and review of prototypes and procedures including data analysis (IRAF/PyRAF). The result of which we applied in the field for scientific studies at Bologna Astronomical Observatory (1.5m) in Loiano, Italy, William Herschel Telescope (4.2m) at LaPalma, Canary Islands and at Calar-Alto Observatory (2.2m) in Spain.
