As a journalist, I would rewrite this article to create a unique piece:
James Wertsch Distinguished University Professor and Chancellor Emeritus at Washington University in St. Louis, Mark S. Wrighton, has been appointed as the new chair of the Saint Louis Science Center’s board of commissioners. His term began on January 1st. In this role, Wrighton works closely with the center’s president to improve the institution and make science, technology, engineering, and math accessible to people in the St. Louis region and beyond through interactive experiences. The Science Center is one of the only free nonprofit science museums in the country and attracts nearly half a million visitors every year, making it one of the largest science centers in the U.S. and abroad.
Before his career in university administration, Wrighton was an accomplished researcher with achievements in photochemistry, surface chemistry, and electrochemistry. He previously served on both the Science Center’s board of commissioners and its board of trustees for many years before taking up his current position as chair.
