Chat Wacharamanotham, Dr.

Chat left UZH and joined Swansea University from 1 July 2022. He will still give courses at UZH, but he is not available for thesis/project supervision until further notice.

Hi! Chat's here! Before joining UZH in November 2015, I worked in the Media Computing Group at RWTH Aachen University in Germany. I contributed to research in input technologies and interaction designs, especially for touch and near-surface input. My current research explores how interactive technologies can help scientists making better decisions in their scientific discovery. In particular, my group is interested in the decisions that are or should be informed by statistics. Current research projects focus in two areas of scientific decisions: reading statistical research reports and planning experiments. We use methods such as Human-Centered Design, Contextual Inquiry, and lab experiments with eye- and motion-tracking systems for scientific inquiries.
