Dionex announced this week that Frank Witney will become its president and CEO effective April 30, replacing Lukas Braunschweiler, who resigned late last year to become CEO of Ruag Holding.
Witney joins Dionex from Affymetrix where he was executive vice president and chief commercial officer. Prior to that he was president and CEO of Panomics from July 2002 until it was acquired by Affymetrix in December 2008.
Protein Forest said this week John Tonkinson was appointed to the newly created position of vice president of global sales and marketing. His appointment took effect March 16.
Tonkinson's responsibility is to grow sales by growing the current sales team and position Protein Forest in the marketplace "based on its development of products and services," the company said in a statement.
He was with HistoRx as vice president of business development before joining Protein Forest.
