A chemist whose work on nanoscale materials and nanoelectronic devices made him, by one 2011 ranking, the most-cited chemist of the preceding decade, and whose lab pioneered using nanowire devices to interface with living cells and tissue. He chaired Harvard's chemistry department and won the 2012 Wolf Prize in Chemistry. In 2021 he was convicted on six federal felony counts, including lying to investigators about his paid role in China's Thousand Talents recruitment program and filing false tax returns — a serious and well-documented fall that ended his Harvard career.
