Ericsson, Stockholm, Sweden

Master Researcher (Lead Research Scientist)

Feb 2008 – May 2015

Positions at Ericsson Research:
Experienced Researcher → Senior Researcher → Project Manager → Master Researcher

Led a group of Ericsson Research engineers working on subjective quality improvements for Ericsson video encoders (in collaboration with Ericsson TV, UK). The work resulted in noticeable improvements in subjective quality of HEVC and H.264 encoders on several types of video content.

Led a 3D video research project (distributed between Stockholm and Lund sites) which:

• Developed 3D video support in a video conferencing system, with stereo and multi-view 3D (video+depth), based on real-time software MV-HEVC codec (encoder/decoder)
• Contributed to standardization of 3D extensions of HEVC/H.265

Author of a number of algorithms in HEVC and 3D video HEVC extensions (deblocking filter, intra-prediction, 3D reference displays SEI, reference picture list construction, non-normative encoder improvements).

Held several leadership roles in HEVC standardization committee (JCT-VC), such as:

• Primary coordinator of Core Experiment on deblocking filtering
• Co- and vice-chair of several Ad Hoc Groups
• Chair of break-out groups (discussions) on: deblocking filter, adaptive loop filter (ALF), high-level syntax
• Coordinator of several subjective video quality tests at HEVC standardization meetings

Contributed algorithms to TENTM (Tandberg, Ericsson and Nokia) submission to HEVC Call for Proposals

Contributed to MPEG ISO Media Base File Format

Tampere University of Technology, Tampere, Finland

Researcher

Jan 2002 – Jan 2008

Worked on algorithms for error-resilient coding of images, video, 3D video and 3D graphics (meshes) (in particular, on multiple description coding).

• Participated in international 3DTV Network of Excellence (NoE) project
• Visiting researcher at Middle East Technical University (METU) in Ankara, Turkey
