NUCoach is a modular health coaching and research platform built by the Consortium on Technology for Proactive Care (CTPC) at Northeastern University. Supported by mobile health technologies, NUCoach is a powerful yet flexible tool that allows health behavior researchers to gather immense amounts of participant data in real world contexts in near real time. Through sensor integrations and experience sampling, we can not only learn more about our participants’ behaviors but be better prepared to intervene in the right context at the right time. NUCoach is exclusively available for use by members of the CTPC.
