Zhaoyi Song 宋昭亦

I am currently a master’s student at Tongji University, working under the supervision of Prof. Rongqing Zhang. Prior to this, I obtained my Bachelor’s degree in Software Engineering from the same institute in 2021.

My research has been centered on operations research for efficient warehousing, specifically focusing on the multi-agent pathfinding problem and the warehouse order picking problem. I aim to develop adaptive algorithms that can learn from their environment, thereby creating intelligent systems that enhance decision-making and problem-solving capabilities.

Looking ahead, I am eager to seek opportunities that allow me to build innovative solutions that both excite me and make a significant impact on people’s lives.
