Hoang H. Nguyen has joined the L3S Research Center of Leibniz University Hannover as a researcher and PhD candidate since February 2020. He was a visiting student and then a research associate at the School of Computing and Information Systems, Singapore Management University, from 2016 to 2018. In 2017, he received his Master of Engineering degree in Computer Science from Ho Chi Minh City University of Technology (HCMUT), Vietnam.

Nguyen has 10+ years of experience in Software Engineering and Graph Mining in the industry and academia. At L3S Research Center, he collaborates with researchers and law enforcement agencies (LEAs) from over fifteen countries and territories to develop new platforms to speed up investigative processes and support LEA decision-making. He also builds frameworks for storing and retrieving blockchain-powered social network data and detecting vulnerabilities in blockchain smart contracts.

His current research interests include Graph Mining, Machine Learning, Multimodal Network Analysis, Program Analysis, Software Security, and Blockchain Smart Contracts.
