John Stephen  West net worth and biography

John West Biography and Net Worth

CEO of Personalis
Personalis’ CEO, John West, first became involved in DNA sequencing and DNA sequence interpretation in 1982. In the 1980’s, he led the development of an automated DNA sequencing system based on pattern recognition from autoradiographs, and licensed software from the lab of Roger Staden at MRC Cambridge, UK for sequence assembly and analysis. In the 1990’s Mr. West was General Manager and subsequently President of Princeton Instruments, a company focused on low light scientific imaging. This technology was used in a number of fluorescent automated DNA sequencing developments. In 2001 Mr. West joined then market leader Applied Biosystems as Vice President of Genetic Analysis. He was subsequently promoted to VP, DNA Platforms. While at Applied Biosystems Mr. West’s group introduced the model 3730xl Genetic Analyzer. This product became the mainstay of almost every major genome center in the world.

In 2004, Mr. West moved to be CEO of Solexa Ltd, a venture capital backed UK company focused primarily on single-molecule DNA sequencing. Mr. West realized that the company’s recent acquisition of DNA cluster technology could be transformative. In 2005 he led Solexa’s reverse merger into US-based and Nasdaq-listed Lynx Therapeutics, and led two PIPE financings totaling almost $100M. The company introduced its first system in mid-2006. Mr. West negotiated the January 2007 acquisition of Solexa by Illumina, Inc for approximately $600M, and stayed as VP of the DNA sequencing business there into 2008. During this time, Illumina became the world leader in next generation DNA sequencing.

From 2009 through mid-2011 Mr. West served as CEO of ViaCyte, Inc, a company leveraging stem cell technology to develop a diabetes cell therapy.

In late 2009 Mr. West’s family became the first healthy family of four to be sequenced. Their experience  working with the Stanford team on genome interpretation led to the foundation of Personalis.

Mr. West received a BS and MS engineering degrees from MIT, and earned an MBA from the University of Pennsylvania’s Wharton School of Business.

Its tests and analytics are used by pharmaceutical companies for translational research, biomarker discovery, and development of personalized cancer therapies, as well as advanced tests are used by physicians to detect cancer recurrence, monitor cancer evolution, and uncover insights for therapy selection. The company offers NeXT Personal, a tumor-informed liquid biopsy test for detection of minimal residual disease (MRD) and recurrence in cancer; and ImmunoID NeXT, a tissue-based test that combines whole exome (DNA) and whole transcriptome (RNA) sequencing data with advanced analytics to provide a multi-dimensional view of the tumor and the tumor microenvironment from a single sample. It also provides NeXT Personal Dx, a tumor-informed liquid biopsy test for detection of MRD and recurrence in cancer; and NeXT Dx, a comprehensive tumor profiling test that unlocks the entire exome (DNA) and transcriptome (RNA) with matched tumor-normal analysis. In addition, the company performs whole exome sequencing (WES) of cancer tissue and matched blood samples for diagnostic companies as an input to their products; and whole genome sequencing (WGS) on human samples for research projects, such as population sequencing initiatives, as well as offers sequencing and data analysis services to support population sequencing initiatives. Its customers include pharmaceutical companies, biopharmaceutical companies, diagnostics companies, universities, non-profits, government entities, and patients. The company was incorporated in 2011 and is headquartered in Fremont, California.
