Peter Saenz

Peter Saenz

Peter Saenz’s research investigates the application of the Internet of Things (IoT) in healthcare, with a central focus on how IoT can be used to improve operational efficiency and equitable patient outcomes. Healthcare systems are plagued by a myriad of problems, including affordability, capacity, and staffing shortages. IoT technologies will be central to solving these problems. Peter seeks to research the policy implications of IoT from different perspectives as well as develop IoT-based technology. Peter has received funding through the NSF’s regional Innovation Corps program and is now applying to the national NSF I-Corps program in addition to an NSF PFI/ TT funding opportunity. As Peter’s doctoral studies progress, he intends to apply for NSF SBIR/STTR grants to help aid in the commercialization of IoT technology.
