Dr. Simon honored as a 2025 Jacobi Medallion recipient

This prestigious award honors a member of the Mount Sinai community who, through long-term service (typically 10 years or more), has made exceptional contributions to the fields of clinical medicine or biomedical research, or has exemplified extraordinary dedication to Mount Sinai.

"I can hardly imagine a point in time at which ambitious and creative virology research could be more important than it is right now.  Congrats to all of you on your progress and on the growing recognition of the value of your efforts."
