I am a PhD student in computer vision and pattern recognition affiliated with both the Institute of Numerical Simulation at the University of Bonn and the Computational Learning and Visual Perception Group at the Institute of Mathematics of the Romanian Academy.

My research interests include both Computer Vision topics like 3D Pose Estimation and object detection but also more general Machine Learning topics like structured prediction and kernel approximation. 

My resumé can be found here and my google scholar account is here.

News

• We have a new article in ICCV 2015. Check the project page for more information.
• I have been selected for a doctoral consortium scholarship at the CVPR 2014.
• Our pose estimation paper was accepted for oral presentation at CVPR 2014.
