Siamak Valizad Fardin
Researcher, Mechanical Engineering
A Mechanical Engineering researcher with an M.Sc. in Applied Design from the University of Tabriz. Currently working at Machine Sazi Tabriz (MST), focusing on vibration analysis, control systems, and nanobeam mechanics.
My research centres on size-dependent vibration behaviour in nanobeams using nonlocal strain gradient theory, with applications in active vibration control via LQR methods. I also have experience in industrial design, finite element analysis, and computational modelling.
My technical interests span vibration and dynamics, control theory, composite materials, machine learning, robotics, artificial intelligence, hydraulic systems, and solid mechanics. I work extensively with engineering software including MATLAB, Mathematica, Ansys, Abaqus, SolidWorks, and programming in Python and C++.
