MIT biology professor Alan D. Grossman shares the story of his medical crisis that began with unexpected lightheadedness on campus in 2002 and led to a heart in 2006. The conversation traces the medical details of sarcoidosis, heart failure, immunosuppression, and recovery, while also showing how Alan kept teaching, mentoring, and leading through it all. After listening, you will gain a broader appreciation of resilience, rare disease research, and the life-saving impact of organ donation. Mary Ellen Wiltrout guides the story from diagnosis to transplant to leadership during the pandemic, with Alan reflecting on what changed in his work, priorities, and perspective. Key topics Alan Grossman explains why his heart does not race when he gets nervous.He shares the day his health changed in July 2002.The initial diagnosis was heart block, which led to a pacemaker.Grossman discusses sarcoidosis, a rare inflammatory autoimmune disease that in his case attacked only the heart.He describes trying immunosuppression and anti-inflammatory treatment.As symptoms advanced, he developed heart failure.He explains how transplant candidacy depends not only on medical severity but also on support systems, infection risk, and the ability to survive the demanding post-transplant period.Grossman walks through how heart transplant surgery is physically straightforward but medically complex because rejection prevention is the real challenge.He explains the role of antibodies and cell markers in the immune system’s response to a transplanted organ.He recounts waiting more than a year for a heart, including one false alarm before the actual transplant offer in 2006.He describes the immediate post-op period, including high-dose steroids, hallucinations, pain, and a broken rib discovered later on an X-ray.He reflects on returning to work, rebuilding his lab, restarting teaching, and later helping create the microbiology graduate program at MIT.He talks about how surviving severe illness made him both more patient and less patient in different ways, and more willing to focus on what he can control.He explains leading the biology department during the pandemic and why his own long experience with immunosuppression shaped his caution around COVID.The episode closes with a direct call to register as an organ donor and to make those wishes known to your family.
