Research and Professional Experience: - Experience developing software tools for semiconductor inspection and metrology machines. - Dynamic system and disturbance modeling. - Robust and optimal servo control design. - Linear/nonlinear control synthesis methods via numerical optimization. - Active/passive actuator saturation avoidance. - Industrial automation (PLC, HMI, SCADA) - Industrial machine vision and implementation. I work as a Software Engineer and developing software tools for reticle inspection devices, used in semiconductor manufacturing. I graduated from the Department of Aerospace Engineering and Mechanics at the University of Minnesota, Twin Cities. My research primarily focused on developing optimal and robust control synthesis methods by solving convex optimization problems. I am highly motivated to work with the most challenging issues in the field of Controls and Systems that leverage interdisciplinary knowledge and integrates Control Theory with mathematical modeling, algorithm development, and hardware prototyping. In addition, I am also interested and have academic experience in exploring Guidance, Navigation, and Controls (GNC) for aerial systems.
- Developing software tools to map stage position error and monitor vibrations for a state of the art reticle inspection machine, used in semiconductor manufacturing. - Developing software tools for mass-scale data visualizations.
