Carmine Elvezio

PhD Student

I'm a PhD Student at the Computer Graphics and User Interfaces Lab at Columbia University, studying AR/VR/MR and 3D graphics, interactions and visualization techniques, under the supervision of Prof. Steven Feiner. I develop 3D systems across several domains including medicine, remote maintenance, space, music, and rehabilitation, working with many technologies including Microsoft HoloLens, Oculus Rift, Unity, Unreal, and OpenGL! I've also contributed to a number of open source frameworks, including MercuryMessaging and GoblinXNA.

Shalva Kohen

Shalva is a master's student currently working on an augmented reality sheet music visualization system called MiXR (Music in Mixed Reality). She has published a two-page paper describing the system in ISMAR 2020. Before that she was second author on a paper describing an AR system to aid doctors in vascular interventions which was published in ISMAR 2019. When things inevitably break she copes by playing the trumpet, stress baking, or kicking things with the Columbia Taekwondo Club
