Meet the team

Randy Yerden
Founder
While working as a laboratory technician at the University of Rochester, Randy created the first device to control oxygen sensing in an incubator. What was intended to be a singular invention quickly gained traction as other labs and colleagues saw the benefits of physiologic oxygen control and began requesting that Randy create similar devices for their studies. Within a few years, BioSpherix Ltd. was born, and with it a revolutionary approach to cell processing. 30 years later, Randy, though now retired, serves as a consultant for the business that he created while enjoying the peace that comes with settling down after a long and fruitful career.
