Dr. Jiju Poovvancheri is an Assistant Professor in the Department of Mathematics and Computing Science, Saint Mary's University, Halifax, canada. Prior to joining SMU, he was a postdoc ( partnering with Dreamcramft Attractions, Victoria) in Graphics lab, Department of Computer Science, University of Victoria, working with Prof. Andrea Tagliasacchi. Prior to UVic, he worked as a postdoc in Geospatial Intelligence Lab, University of Calgary, with Prof. Ruisheng Wang . He received his PhD (2015) from Indian Institute of Technology, Madras under the supervision of Prof. Ramanathan Muthuganapathy and masters (2009) in computer science from National Institute of Technology, Karnataka, India.


Broadly, my research interests lie in computer graphics, 3D vision and machine learning. I am interested in developing efficient algorithms, and computational tools for 3D sensing and modeling of the objects and the world around us, with interesting applications in virtual/augmented reality, autonomous robotics, urban planning & simulation, bio-mechanical studies, collective behavior etc.. I am also interested in geometric problems related to shape analysis, matching and retrieval. My current focus include the following. -Point cloud processing 3D reconstruction -Volumetric video technology -Spatial data structures -Geometric deep learning​ -Performance capture for VR/AR
