HSD Scientist elected President of Sigma Xi
Dr. Ann Houston Williams, field studies coordinator for the Epidemiology and Biomarkers Branch of HSD, has been elected president of Sigma Xi, the international honor society of science and engineering. Her election came earlier this month at the society's annual meeting and student research conference, held this year in Detroit.
Founded in 1886, Sigma Xi has about 65,000 members and more than 500 chapters in North America and overseas. The society publishes award-winning American Scientist magazine and sponsors a variety of programs that support science and engineering. More than 200 Sigma Xi members have received the Nobel Prize. A 31-year member of the honor society, Ann has previously served as a chapter officer, on the society's board of directors and on Sigma Xi's administrative staff as director of chapter programs.
