Alexander was born in 1973 and have an MSc degree in Physics specializing in methods of mathematical physics.

He joined Tydex in 1997, following post-graduate study at the Faculty of Physics of St. Petersburg State University. The company was growing fast and was being active in almost all fields of optical business. That gave him the opportunity to experience the widest range of optical components and materials, from UV to THz, from just protective windows to precise laser active elements. Due to a shortage of specialist staff, each of them had to provide complete support to his projects, starting from discussion of technical details with the customer, through to buying raw materials and supervising the manufacturing process to final QC, customs clearance, billing and collecting payments. Thanks to this, he knows the complete business process in Tydex ab ovo usque ad mala.

As the company evolved Tydex began to run our own production workshop, QC department, logistics department and commercial unit. During this expansion, the company dropped some activities to focus on the fields where it was the strongest and the most competitive. Sales engineers in the commercial unit share these fields such a way that the customer gets the feedback to his request from the most qualified person in the field of his interests.

At present Alexander is an optical coating department manager. He is also responsible for supervising the development of new challenging technical issues in the company. For example, he headed the establishment of the spectroscopy measurements department, the modernization of our interferometers and participated in elaborating the Golay Detector calibration procedures. He  also supervised the evolution and support of the corporate network.

During his work at Tydex  Alexander has represented the company at over a dozen Russian and international conferences and trade fairs. His English is fluent.

In his spare time he enjoys field archaeology.
