Dr. Varodom (Dew) Toochinda
Dr.Varodom Toochinda, often addressed by his nickname “Dew,” is a researcher/lecturer at the Research and Development Institute of Industrial Production Technology (RDiPT), Faculty of Engineering, Kasetsart University, Thailand. He has his research interests in systems and control and is working on developing controllers for various CNC machines and robots.
While studying at UMASS, he worked in the Design and Analysis of Control System Laboratory (DACSLAB) with his advisors, Prof.Yossi Chait and Prof. Christopher V. Hollot, on active noise control and multivariable control design.
