PhyNexus, Inc. was founded in May, 2002 by Douglas Gjerde, PhD (PhyNexus'  CEO). In 1997, Gjerde was a founder of Transgenomic, Inc. Transgenomic's business plan was to develop and sell state-of-the-art sample separation and processing tools for DNA and RNA, where the core technology was provided through acquisition of Sarasep, originally founded by Gjerde in 1990. This ultimately led to Transgenomic's $70M IPO in June, 2000. Before founding Sarasep, Gjerde worked for large and small technology companies, including Exxon Research, Wescan Instruments and Alltech Technologies.
