I am a part-time Clinical Research Fellow (Department of Clinical Research, Faculty of Infectious and Tropical Diseases), seconded to ALERT, in Addis Ababa - Ethiopia as leprosy specialist.

My duties include organizing and conducting clinical research especially in leprosy, cutaneous leishmania and other skin NTDs. I look after leprosy patients as their clinician at ALERT hospital. I am part of the Leprosy Expert Advisory Group which works with the Ministry of Health of Ethiopia.

My PhD at LSHTM, under Professor Diana Lockwood, was based on a clinical trial looking at treatments for leprosy reactions. I continue to work on this field by being part of the ENLIST group which specifically looks at Erythema Nodosum Leprosum.

A Diploma in Clinical Dermatology has opened further doors and I am now a co-PI on a new study on stigmatizing skin diseases funded by the UK NIHR RIGHT: Skin Health Africa Research Programme (SHARP) with Steve Walker as the pricipal investigator.

I am a member of the international techincal committee for ILEP and actively involved in the NNN Skin NTD cross-cutting group.

I supervise LSHTM Masters students during their summer projects in Ethiopia.

I regularly teach undergraduates, junior medical staff and nurses in the clinics as well as giving lectures in Leprosy and skin diseases to various clinical and non-clinical audiences. 


Fields of research I am involved in include:

- Clinical Trials

- Health Related Quality of Life 

- Leprosy mapping studies

- Prevention of Disability

- Skin NTDs

- I am an active member of the Erythema Nodosum Leprosum International STudy (ENLIST) Group, which aim at improving the understnading and management of ENL.
