Scientific Advisory Board

Since its inception, Praesidium has been rooted in validated science and exhaustive Research & Development around new and disruptive applications for our non-contact vital sign detection technology – which we call BioFi.  The technical and practical possibilities for our BioFi technology are vast.  As we move our technology out of the lab and into commerce, we have empaneled a Scientific Advisory Board comprised of leading medical professionals from outside of the company to bring every-day relevance to the endless possibilities for this technology.  The Praesidium SAB’s charter is twofold, namely to:

  • Provide on-going technical guidance on what constitutes “Best Practice” and “Generally Accepted Guidelines” for data interpretation related to human Heart Rate, Heart Rate Variability, and Respiration, among other vital sign data.

  • Challenge the company to pursue additional Research & Development possibilities for our BioFi technology.  These possibilities are often born from stimulating debate and discussion among the SAB members with questions that typically starts with “What if . . .?, or “Have we considered . . . ?
