About me

Hi! I'm Ravit Pichayavet, a fourth-year Ph.D. student in Supply Chain Engineering at the H. Milton Stewart School of Industrial and Systems Engineering (ISyE) . I earned my Bachelor degree in Electrical Engineering from Chulalongkorn University in Bangkok, Thailand. My research interests are in planning and optimization in logistics and supply chain systems. I have worked on the middle-mile and last-mile logistics problems under the supervision of Professor Alan Erera (my primary advisor) and Professor Alejandro Toriello. My recent research is on shipment resource allocation problem and demand forecasting in collaboration with our industry partner and Physical Internet Lab. You can also find my studying status on ISyE students page.
