Harvard Kennedy School


Giffin Daughtridge makes multitasking look easy.

Cool, calm, and collected when we chatted, Daughtridge doesn’t give off any indication that he is in the middle of completing dual degrees in medicine from the University of Pennsylvania and a Masters in Public Policy from the Harvard Kennedy School of Government.

As if that weren’t enough, he is also trying to put an end to the spread of HIV as the founder and CEO of UrSure. UrSure has created a noninvasive and cheap urine test to make sure those who are at a high risk of getting HIV adhere to the daily usage of the preventative drug Pre-exposure prophylaxis, or PrEP.

With the urine tests, Giffin and UrSure can assess whether or not the more than 100,000 patients who use PReP take their pills daily. This differs greatly from the current methods that check adherence, which are more invasive and sometimes painful.

Find out more about what Daughtridge and UrSure are up to, and how the working out of the i-lab has helped the venture during this vital stage of growth in our new Harvard Innovation Labs Stories podcast series.
