PICI leaders, investigators, and collaborators contributing to nearly 100 posters, presentations, and panels throughout the meeting

SAN FRANCISCO, April 17, 2026 /PRNewswire/ — The Parker Institute for Cancer Immunotherapy (PICI), today announced that research and expertise from across its network will be showcased at the American Association for Cancer Research Annual Meeting, taking place April 17- 22 in San Diego, California. PICI leaders, investigators, and collaborators are contributing to nearly 100 posters, presentations, and discussions throughout the program – demonstrating the depth and breadth of the network’s contributions to the field of cancer immunotherapy.

Notably, PICI’s newly appointed Chief of External Affairs Kristen Dahlgren is a co-chair of this year’s Annual Meeting Program Committee. She will also chair an educational session on communicating beyond academic audiences and a forum designed to help attendees gain actionable insights to improve trial efficiency, broaden representation, and enhance the relevance and impact of their research. PICI is also unveiling the latest results from the RADIOHEAD cohort, with the largest plasma proteomics study of its kind for checkpoint inhibitor therapy, alongside new methylation-based tools for monitoring tumor dynamics.

Additionally, Antoni Ribas, Director of the PICI Center at UCLA, will be honored with the 2026 AACR-Margaret Foti Award for Leadership and Extraordinary Achievements in Cancer Research. This award is presented annually to an individual whose leadership and extraordinary achievements in cancer research have made a major impact in the field.

“Cancer doesn’t wait, and neither do the researchers of the PICI Network. The work our investigators are presenting at AACR 2026 – across cell therapies, resistance mechanisms, precision platforms and beyond – represents years of collaboration designed to move faster than any single institution could alone,” said Dr. Knudsen. “Through our investigators and portfolio companies, we are developing and accelerating access to breakthrough cancer therapies and curating innovation from discovery to commercialization, with the vision of converting all cancers to curable diseases.”
