A mark of a strong research institution is not just the discoveries it produces. It must also make investments into the sustainability of science across decades. In part this is accomplished through mentored, protected time for our subspecialty fellows through federal training grants. The Department of Internal Medicine is home to six different NIH-funded T32 training grants, many of which have been running for decades. One of those T32s, the Research Training in Infectious Diseases grant, was just renewed for a sixth time.
