Professor Andrew Hayward qualified in Medicine at United Medical and Dental Schools London. He undertook a senior house officer rotation in Public Health in Leicester before joining the Communicable Disease Surveillance Centre (now Centre for Infection at Public Health England) as a research registrar in the Respiratory Section. He was awarded a distinction for an MSc in Communicable Disease Epidemiology at the London School of Hygiene and Tropical Medicine before completing his public health training in London and Nottingham. He was a lecturer in public health at University of Nottingham before moving to UCL as Senior Lecturer to establish the Centre for Infectious Disease Epidemiology in the Department of Infectious Diseases and Population Health, When he arrived at UCL there was very strong research on HIV and STIs but very little research on other infections within the department. He established a successful group focussing on acute respiratory infections, tuberculosis, hospital-acquired infection, antimicrobial prescribing and resistance and infections in hard to reach groups. He became UCL Professor of Infectious Disease Epidemiology and Inclusion Health in 2014. In 2015 he established a new Department of Infectious Disease Informatics in the new UCL Institute of Health Informatics, this move enabled his group to take advantage of the highly multidisciplinary world-class research environment and outstanding opportunities in Big Data research. In 2016 Andrew was appointed as Deputy Director of the Institute of Health Informatics with responsibility for Learning Health Systems and Public Health.

In January 2017 Andrew became interim Director of the UCL Institute of Epidemiology and Health Care and was confirmed as substantive Institute Director in June 2017.

Andrew plays an active role in Policy and Guideline Development through membership of the Joint Committee on Vaccination and Immunisation Influenza Subgroup and of the New and Emerging Respiratory Threats Advisory Group. He chaired the NICE national guideline development group for Tuberculosis in Underserved Groups and co-chaired the 2014-16 NICE group revising all national tuberculosis guidance. He is a trustee of the Pathway Homeless Health Charity and member of the Research Advisory Board of the Groundswell Homeless Health Peer Advocacy charity.
