Andrej obtained a MSc degree in Structural Engineering from Technical University of Denmark in 2012. After the graduation he started the position as a consulting project engineer within the design of civil structures. Being involved in diverse design activities, he obtained experience in the design of steel and reinforces concrete structures, as well as, in the advanced nonlinear FEM analysis of nonstandard components and connections. While being proficient in several commercial software packages, Andrej has a strong understanding of the underlying theory.
In 2013 Andrej moved to Norway and started the position within structural calculations of drilling equipment for the offshore oil and gas industry. Here he expanded his technical experience and got familiar with offshore design and certification standards. He was also involved in the submission process of design documentation for third-party certification (DNV, ABS).
The interest in drilling machines and offshore mechanical systems encouraged Andrej to start a PhD position at Norwegian University of Science and Technology. Within the first two years he obtained significant knowledge in robotics, automation, mathematical dynamic modeling of rigid and flexible systems, as well as, knowledge in nonlinear control theory. He has an interest in both theoretical development and practical applications. He designed and built a laboratory cell for testing of control and estimation algorithms for a small-scale knuckle boom crane. While working with the lab setup he got initial experience in automation and electrical engineering.
