Youngjun Cho

Brief biography
Youngjun Cho is Associate Professor in the department of computer science at UCL and one of the key academic staff in GDI and MSc DDI (Disability, Design and Innovation). Also, he is a co-founder of KIT-AR (UCL/Sintef spinout company). He explores, builds and evaluates novel techniques and technologies for the next generation of artificial intelligence-powered physiological computing1 that boosts disability technology innovation.
He has pioneered mobile thermal imaging-based physiological sensing and automated detection of mental states (e.g. stress). He obtained a PhD in computational physiology from Faculty of Brain Sciences and UCLIC at UCL (and obtained a MSc in Robotics, a BSc in ICT - summa cum laude). In 2011-2018, he worked as a senior research scientist at LG Electronics (full-time: 2011-2015, leave of absence: 2015-2018) and led a variety of industrial research projects. Amongst his contributions, novel 3D input and gesture recognition technologies (for advanced touch screen solutions in vehicles) were successfully commercialised in collaboration with automobile manufacturers including Porsche and BMW.
At UCL, his research has been funded by EPSRC, Bentley Motors, EC H2020, NTT, and DfID. Also, his earlier academic studies (including 4-year BSc, 2-year MSc, 3-year PhD) were fully funded - the primary funders includes prestigious scholarship/grant bodies: EC H2020, UCL-ORS, National Research Foundation of Korea, LG and Samsung. He has authored more than 70 articles (including patents) in areas related to affective, physiological computing, machine learning, human-computer interaction, accessible user interfaces, and multimodal sensing and feedback. Some of the achievements have been featured in forums for the general public such as BBC News, Phys.Org, Imaging and Machine Vision Europe, Science Daily, and SBS News.
1His definition of physiological computing is technology that helps us listen to our physiological and psychological needs and adapts its functionality. Its three technical components are physiological sensing, affect recognition and bio-feedback.
