About Me

I did my undergraduate studies in a Double Bachelor’s Degree program in Switzerland and Finland (Computer Science and Information Technology). Then, I worked 2 years as a data/software engineer in a financial institution in Switzerland. Being passionate about AR/VR and AI, I wanted to continue studying the new technologies that will build tomorrow’s world and doing research in these fields. I seized the opportunity to participate in a new innovative Triple Master’s Degree program: Erasmus Mundus Japan - Master of Science in Imaging and Light in Extended Reality (IMLEX) which took place in Finland, France and Japan. I was lucky enough to be selected as a EMJMD Scholar. After graduation, I continued during 6 months as a Research student at Chiba University in Japan in the field of vision science & visual perception in XR. Now, I have been accepted as a PhD student at Tokyo Institute of Technology and I have also been selected as a Scholar in Tokyo Tech Program for Development of Next-Generation Front-Runners with Comprehensive Knowledge and Humanity. Belonging to the field of neuroscience & vision science, I am currently investigating the interactions between color perception and the phenomena of presence and cross-modal transfers in XR.
