The document discusses challenges with mHealth (mobile health) research. It notes the rapid explosion of data inputs and need for high throughput analyses to handle complex, streaming data from various sensors and sources. Key challenges include technology development timelines not aligning with the slow NIH funding process, the need for interdisciplinary teams over traditional academic models, and developing research methodologies for collecting and analyzing mHealth data. The document announces an upcoming workshop to assess alternate research methods to randomized controlled trials which are difficult in fast-paced technology, and NIH training institutes to improve skills around using mHealth in research and cross-disciplinary collaboration.
