Junzi Sun

Dr. Junzi Sun serves as an Assistant Professor at TU Delft's Faculty of Aerospace Engineering, where he leads innovative research in air traffic management and sustainable aviation. His academic journey began with telecommunications and computer science in China, followed by aerospace studies in Europe, culminating in his PhD from TU Delft focusing on aircraft performance modeling. His significant contributions include developing widely-used open-source tools like pyModeS and OpenAP, and authoring the comprehensive open-access book "The 1090 Megahertz Riddle." As Editor-in-Chief of the Journal of Open Aviation Science, he champions open science principles in aviation research. His research portfolio spans aircraft surveillance technologies, trajectory optimization, and environmental impact assessment of aviation, with his work garnering over 1,400 citations. His OpenAP aircraft performance model has become a standard tool in air transportation studies, while his work on flight data analysis and sustainability has earned him the SESAR Young Scientist Award in 2019. Currently, he leads projects investigating contrail formation mitigation and developing AI-based solutions for trajectory prediction, while continuing to advocate for open data and reproducible research in aviation science.
