Medical Expert of the Month: Dr. Kenneth Lyons Jones

Dr. Jones is the Chief of the Division of Dysmorphology/Teratology at the Department of Pediatrics at the University of California, San Diego. He is also a pioneer in the Teratology world. Dr. Jones was one of just two doctors who first identified Fetal Alcohol Syndrome (FAS) in 1973. He is considered to be the father of FAS. His research has focused on the clinical delineation of birth defects, mechanisms of normal and abnormal morphogenesis and the recognition of new human teratogens. Dr. Jones established OTIS’ California affiliate, the CTIS Pregnancy Health Information Line, which is funded by the State of California. Its toll-free hotline has been serving California women since 1979.
