Tim Nielsen

I’m a scientist and senior Medical Affairs professional with 12 years’ industry experience, with special Immunology expertise and Oncology experience in haematology and solid cancers. I also work as an independent advisor to global pharma and investment companies on Medical Affairs operations, and more generally on scientific matters related to my areas of expertise, including biochemistry, immunology, and biologic and biosimilar medicines.

I have developed and delivered national Medical Affairs strategy, evidence generation programs, and strategic KOL engagement and development plans aligned cross-functionally and to overarching business strategy. I have a strong track record of building deeply loyal KOL relationships (many > 10 years) and developing field medical (MSL) capabilities. Most recently, I built and led Celltrion ANZ’s Medical Affairs function around the flagship product REMSIMA SC (subcutaneous infliximab) and three biosimilars in the Immunology and Oncology portfolios. Core strengths include strategic framing, clarity of communication, accountability, and the ability to translate complex science and biotechnology into clear, practical medical strategy.
