Industrial Research

I have taken part in the founding of Artesis Technology Systems in 1998, and worked there as a senior research scientist as well as a shareholder until 2002. Artesis is a research company that develops original technologies in the area of model-based fault detection and condition monitoring for electrical machinery, and is a subsidiary of Arcelik A.S., a major European manufacturer of domestic appliances, better known for its Beko brand of products. My responsibilities at Artesis consisted of conducting and supervising the main research activities, including the modeling and analysis of nonlinear electro-mechanical systems; development of mathematical methods for system identification and fault detection, developing algorithms for control, parameter estimation, signal processing, and optimization, and implementing into high-tech industrial products. The original technology developed at Artesis has won several prestigious awards, among them the Technology Grand Prize of 1999, the biggest national technology award.
