Infectious Diseases


Dr. Adachi is a Clinical Assistant Professor in the Department of Pediatrics, Division of Infectious Diseases. She received her BA and MA from Stanford University and received her MD from UC San Diego School of Medicine in 2008. She completed her UCLA pediatrics internship and residency at UCLA in 2011 and later a three-year UCLA clinical fellowship in pediatric infectious diseases in 2015. She also completed an additional two-year postdoctoral pediatric infectious diseases research fellowship at UCLA focusing on perinatal infections from 2015-2017. She is board certified in both pediatrics (2011) and pediatric infectious diseases (2015). Her research interests for the past five years include global maternal-child health, particularly perinatal infections (CMV, Zika virus, and STIs including chlamydia, gonorrhea, syphilis). Her current research projects include investigating occult congenital infections in HIV-exposed infants, primarily from Brazil and South Africa, as well as various clinical research studies on outcomes of infants with in utero Zika-exposure in Brazil in collaboration with FIOUPIC (UC FIOCRUZ Perinatal Infections Collaborative).
