The citation is "For sustained leadership in the construction and support of essential IT services” and here are some quotes from his nomination letter: Joseph Tam is the rock of the Mathematics Department’s IT team… for over 30 years… (he) oversees a large diverse ecosystem of network and computational infrastructure. Our ability to get things done depends critically on IT services that must be “always on” … and Joe is the one we rely on to keep moving forward... Joe has the amazing depth of knowledge to give wise, on-point, security-conscious advice to people of all kinds on problems of all sorts… During the lockdown days of the pandemic, Joe even made bicycle-powered house calls to some faculty and staff who needed help with the online connections at their home offices.
