Tariq Ghayur, PhD, Tariq Ghayur Consulting, LLC and Entrepreneur in Residence, FairJourney Biologics
Dr. Ghayur retired from AbbVie (July 2021) and works as an independent consultant. He has 30+ years’ experience leading multi-disciplinary and cross-therapeutic area Biologics discovery programs and developing novel Biologics platforms. Several biologics programs resulted in clinical development candidates. Dr. Ghayur led the team that pioneered the discovery and development of the Dual – variable – Domain -Ig (DVD-Ig) and other multi-specific platforms. Dr. Ghayur also led the team that defined the uptake, intracellular trafficking, and lysosomal degradation of anti-TNF mAbs/DVD-Ig, resulting in the concept of anti-TNF-ADC (next-Gen anti-TNF). In addition, Dr. Ghayur proposed and helped implement several corporate-wide (Abbott & AbbVie) initiatives to foster cross-functional/cross-TA collaborations to bring forward innovative concepts/programs.
