Summary

I’m a highly motivated and results-driven Machine/Deep Learning Research Engineer, currently leading the R&D Team at Bodymapp Pty Ltd. I completed my Ph.D. in Deep Learning at the University of Sydney under the supervision of Prof. Dong Xu. My expertise lies in devising and enhancing AI algorithms for 2D & 3D visual applications. I have published research papers in top AI Conferences and Journals, including CVPR, T-PAMI, and T-IP. My skills also include building, managing, and optimizing DevOps and AWS MLOps pipelines, which enhance the speed and accuracy of 3D body mesh reconstruction and measurement engines. Additionally, I am experienced in implementing and collecting ML annotations to continuously improve neural net models.

I possess a rich portfolio of research in AI, covering 2D/3D image/video de-noising, 3D human point cloud and mesh reconstruction, SLAM, and multi-modality/multi-domain transfer learning, with applications aimed at practical solutions.
