Yohanah became interested in the inquest process, in particular actions against the police, after the death of a family friend in police custody. She has always had an interest in human rights law but officially started to look into at depth whilst studying law at university. 

Yohanah joined INQUEST in 2018 as a Casework Volunteer and went on to be a Casework Assistant. In 2022, reflecting her skills and development, she became a Caseworker. She previously led on the building and maintenance of the INQUEST Library Online, a resource for members of the INQUEST Lawyers Group.
