My research ambition is to understand and enhance human cognition, performance, and development. To achieve that I specialize in methods for multimodal modeling and nonlinear dynamic systems. The domains of interest include human-computer interaction, social interaction, collaborative learning, and surgical expertise. I have been conducting empirical research since 2010 and have a holistic experience with computer-supported collaborative work (CSCW) and human-computer interaction (HCI) research. The application domains of my research span (collaborative) problem solving, computer-supported collaborative learning, source-code reading, subtitles reading, and high-precision motor control, i.e., microsurgery or indoor climbing.
