Dr. Torsten Bullmann studied biology at the University of Leipzig, Germany. He received his diploma in biology in 2001 and his doctoral degree with summa cum laude in 2009, both from University of Leipzig. During his post-doc he worked for more than 7 year in Japan: at the RIKEN Center for Developmental Biology, at the RIKEN Quantitative Biology Center and at the Department for Informatics at the Kyoto university. In 2017 he returned to Germany to work as a full time lecturer for bioinformatics at the University for Applied Sciences Mittweida where he was tenured in 2018. He teached bachelor and master courses on bioinformatics, biological databases, programming, systems biology and modelling.

In 2019 he returned to Leipzig university to continue his studies on the role of microtubule associated protein tau in the regulation of neuronal activity during hibernation. His research interests include basic neuroscience, systems biology and application of machine learning. Currently he is using machine learning for the dense reconstruction of neuronal tissue from series of electron microscopy images as well as CMOS-based high density microelectrode arrays recordings of neuronal activity at different spatio-temporal scales. He is maintaining active collaborations with Kyoto university and ETH Zurich. During his free time he is enjoying kayaking and playing volleyball.
