I Nyoman Suprapta Winaya is a professor at the Mechanical Engineering Program, Faculty of Engineering, Udayana University. Winaya earned his Bachelor's degree from Udayana University in 1994, his Master's degree from Dalhousie University, Canada, and his Ph.D. from Niigata University, Japan. His primary research focuses on thermal machines, such as combustion/gasification/pyrolysis techniques, capitalizing on the use of coal fuel, co-firing in CFB boilers, and the conversion of renewable, waste/biomass into clean energy.

Winaya was appointed Professor in 2013 by the Ministry of Education and Culture of Indonesia in the field of Energy Conversion Systems. Currently, he leads a New Renewable Energy and Energy Conservation (NRCE) Research Group. Several significant innovations have been discovered, among them is the high volatile capture from fuel to reduce dioxin using porous solid particles as bed material. A new method has been developed to evaluate the horizontal dispersion of solids loaded at high bed temperatures for commercial purposes. The development of several waste residue and medical waste thermal machines continues to increase in size, in addition to ongoing research on renewable energy.

Professor Winaya has a strong desire and commitment to transfer the results of his research for application in the industrial world. Winaya is a member of the Senate of Udayana University, the Indonesian Fuel Experts Association, the Indonesian Mechanical Engineering Association, the American Society of Mechanical Engineering, and the Japanese Society of Chemical Engineering.
