Liang Wang is currently an associate professor in the Center for Interdisciplinary Research in Computer Science (前沿交叉中心, CIC), Institute of Computer Software (计算机软件研究所, ICS), State Key Laboratory for Novel Software Technology, Department of Computer Science and Technology in Nanjing University. Before he joined ICS, he received his B.Sc. and Ph.D. degree from the Department of Computer Science and Technology in Nanjing University in 2007 and 2014, respectively.
His research interests include: Collective Intelligence, Open Source Software, Computer System Education, Activity and Emotion Recognition, and Pervasive Computing.
He is a member of the CCF, and a co-founder of the OSS Compass Community.
We are always looking for self-motivated students. Send me emails if you are interested in joining us.

Recently, we have been working on understanding and measuring the collaborative development of open source software (OSS) projects using entropy and information theory. Our work on quantifying the evolution of social communities in OSS projects with indices developed from information entropy is published in FSE 2022:

InProceedings of the30th ACM Joint European Software Engineering Conference and Symposiumon the Foundations of Software Engineering (ESEC/FSE ’22), November 14�18, 2022, Singapore, Singapore. CCF-A.
We propose an approach to measure the diversity of an OSS project’s forks with the Rao’s quadratic entropy, which is published in ASE 2023:

We also conduct research on understanding the emotions during computer programming:

Large swarms of UAVs is another case of large-scale, machine-based collective intelligence, compared to the global-scale human collective intelligence emerges from the cooperation around OSS projects. We have conducted research on enabling technologies of collective intelligence for UAVs using reinforcement learning and AI technologies:
