David J. Glass

David J. Glass (born 1961) is an American biomedical scientist known for elucidating the mechanisms by which skeletal muscle undergoes hypertrophy and atrophy. He played a role in discovering the "MuSK protein receptor" (Muscle Specific-kinase) that is responsible for formation of the neuromuscular junction, and discovered the mechanism by which MuSK is activated - it's a receptor for the motor neuron-secreted protein, agrin. He also wrote an influential book aimed at teaching biology graduate students how to design their experiments.

Glass is an elected member of the National Academy of Sciences and the American Association for the Advancement of Science. Earlier, he was elected to the American Society for Clinical Investigation. He has more than 35 patents.

Glass is also a playwright. His play, "Love + Science" was produced Off-Broadway in New York City in 2023.. His most recent play is "Spare Parts," which is being presented at Theatre Row (New York City) in March and April of 2026.
