Ali Judd, Senior Epidemiologist

Ali is an epidemiologist and has worked in HIV and hepatitis C since 1995 and with the MRC Clinical Trials Unit since 2005.  She leads a programme of work on the epidemiology of HIV and ART in children and young people in the UK and Europe, and leads a study investigating hepatitis C treatment options for pregnant women.  She gained an MSc and a PhD in Epidemiology at the London School of Hygiene and Tropical Medicine.

She is Principal Investigator for the Collaborative HIV Paediatric Study (CHIPS), which is a cohort of HIV-infected children in the UK and Ireland, and the CHIPS+ cohort which is following young people in CHIPS after they transfer to adult HIV care.  She is also Principal Investigator for the Adolescents and Adults Living with Perinatal HIV (AALPHI) cohort of perinatally-HIV infected young people and a comparison group of HIV-negative controls.  She co-coordinates the European Pregnancy and Paediatric HIV Cohort Collaboration (EPPICC), which is part of the Paediatric European Network for the Treatment of AIDS (PENTA).  She is also a co-investigator in the International AIDS Society Collaborative Initiative for Paediatric HIV Education and Research (CIPHER) Cohort Collaboration.  Ali leads the HCVAVERT study, which is exploring treatment options for pregnant women living with hepatitis C.
