The 3^rd PICI at MSK scientific symposium was virtually held on July 22^nd, 2020. Organized annually, the day-long symposium was a platform to showcase the pioneering research supported by PICI to a wider MSK audience. In 2020, we had close to 250 attendees including MSK and PICI leadership, postdocs, graduate students, medical fellows and non-PICI and PICI investigators. The keynote address was delivered by Dr. Michel Sadelain on new Directions in CAR T cell engineering. The broad spectrum of symposium talks included snapshots of work presented by eleven researchers in five sessions dedicated to: CAR T cells, Checkpoint Blockade, Cellular Therapy, and Metabolomics/Microbiome. In addition, Dr. Francesca Gany and Louis Voigt spoke about the initiatives of the Cancer Health Equity Research Program at MSK and discussed novel ways to address health care disparities through clinical trials participation. The symposium was an opportunity for us to highlight the innovative research supported by PICI at MSK, and a platform to foster new collaborations between PICI members and the larger research community at MSK.

The 2^nd PICI at MSK scientific symposium was held on June 17^th, 2019 at the Zuckerman Research Center at MSK. Organized annually, the day-long symposium was a platform to showcase the pioneering research supported by PICI to a wider MSK audience. In 2019, we had close to 200 attendees including MSK and PICI leadership, postdocs, graduate students, medical fellows and non-PICI and PICI investigators. The keynote address was by the Immunology Program Chair, Dr. Alexander Rudensky on ‘Regulatory T cells, Inflammation and Cancer’.  The broad spectrum of symposium talks included snapshots of work presented by fourteen researchers in five sessions dedicated to: Tumor Antigen Discovery/Oncolytic Viruses, Cell Therapy, Tumor Microenvironment/Microbiome, Checkpoint Blockade and Novel Technologies. In addition, Dr. Carol Brown (Director, Office of Diversity Programs in Clinical Care, Research and Training) spoke about the initiatives of the Cancer Health Equity Research Program at MSK and discussed novel ways to address health care disparities through clinical trials participation. The symposium was an opportunity for us to highlight the innovative research supported by PICI at MSK, and a platform to foster new collaborations between PICI members and the larger research community at MSK.

The first PICI at MSK scientific symposium was held on March 30^th, 2018 at the Zuckerman Research Center Auditorium at MSK. The daylong symposium was a platform to showcase research supported by PICI to a wider MSK audience. Dr. Nina Bhardwaj from the Icahn School of Medicine at Mt Sinai was the keynote speaker and gave a talk on ‘Targeting innate immunity to promote cancer immune control.’ Over 250 people attended the symposium. The day long symposium included presentations by eighteen MSK-PICI researchers in sessions dedicated to: Cellular Therapy, Checkpoint blockade responses, Tumor microenvironment/Metabolomics/ Microbiome, Tumor antigen discovery/Oncolytic vectors and Single cell and Multiplex imaging technologies. The symposium was an opportunity for us to highlight the innovative and exciting projects supported by PICI at MSK and help foster new collaborations within the larger research community.
