I'm not a researcher or academic, but when I think of roughly how long it takes me to do meaningful deep work and produce a project of any significance, I'm struck by the fact that his 800 papers isn't a red flag?

The physician and neuropathologist conducted research at the University of California San Diego (UCSD) for decades, and his drive, curiosity, and productivity propelled him into the top ranks of scholars on Alzheimer’s and Parkinson’s disease. His roughly 800 research papers, many on how those conditions damage synapses, the junctions between neurons, have made him one of the most cited scientists in his field.
