Bridging Geometry, Reality & Intelligence

I am an Assistant Professor at the Department of Electrical and Information Engineering (DTETI), Faculty of Engineering, Universitas Gadjah Mada (UGM), Indonesia. My research is mainly in the area of geometry data processing and mixed reality (virtual reality and augmented reality).

My works are published in top-tier journals in computer graphics, such as ACM Transactions on Graphics and Eurographics' Computer Graphics Forum; and presented at top-level conferences including ACM SIGGRAPH, Eurographics, and Eurographics' Symposium on Geometry Processing (SGP).

My broader research vision is to develop computational tools that elegantly encode geometric structure, from spectral analysis of curved surfaces to immersive virtual environments, and to apply these tools in education, engineering, and cultural heritage preservation.
