From a reckless walk across Kenya to a career in global health: Lessons from a lifelong journey with Professor Koya Ariyoshi

2025 Heath Clark Lecture

Graphic with text - 2025 Heath Clark lecture with Professor Koya Ariyoshi

Heath Clark Lecture, a lectureship in the History and Progress of Preventive Medicine and Tropical Hygiene, was founded in 1929 with funds donated to the University of London by Mr Charles Heath Clark – a philanthropic businessman interested in public health and education. It is awarded annually to a notable overseas academic and offers a three-month residency at LSHTM, together with a specific requirement to make a public lecture.

In this year’s Heath Clark Lecture, Professor Koya Ariyoshi will reflect on his 35-year academic journey—from laboratory research in virology and immunology on HIV/AIDS, to clinical and field-based epidemiology in tropical medicine and global health. He will recount an adventurous and formative 500-km solo walk across Tsavo National Park in Kenya in 1983, undertaken in his twenties along what would later be recognised as part of trans-African highway associated with the early spread of HIV.

Drawing from this experience and the decades of global engagement that followed, Professor Ariyoshi will share the most important lessons he has learned as a global health professional. He will also discuss his continuing efforts to foster deeper collaboration between Japan and UK, grounded in his belief that Japan can – and should – play a greater role in global health. 

The lecture will take place from 17:30 - 18:30, followed by a 1-hour in-person drinks reception in the Pumphandle Social.
