I was shocked and saddened to hear about Muhammed's passing. I'd only met him a few times, but he certainly made an impression. He was incredibly intelligent and accomplished and so committed to improving medical practice and education. I enjoyed learning about the innovations he and his brother had implemented at the practice. We had talked about collaborating on some international work, but sadly the pandemic came along and it fell by the wayside. My deepest condolences to all of his family, friends and colleagues.
