“Today, we are thrilled to announce that Dr. John Quisel has joined the Gossamer team," said Faheem Hasnain, Chairman, Co-Founder and CEO of Gossamer Bio. “Not only is Dr. Quisel a recognized industry leader with a proven track record of success, but he also brings unique strategic insights and experience in PAH, which will be invaluable. We are confident that Dr. Quisel’s appointment enhances our ability to get seralutinib to patients.”

“I am honored to join Gossamer’s Board at this pivotal moment for the Company,” said Dr. Quisel. “Despite recent advances, PAH remains a progressive and fatal disease, and for this reason I am excited to rejoin the fight against PAH with Gossamer.”

Dr. Quisel is currently the President and CEO of Disc Medicine, a position he has held since January 2020 and during which time, the company established a multi-product portfolio of hematology programs and became a publicly-traded company.

Prior to Acceleron, he was an attorney at the firms Ropes & Gray and Foley Hoag.
