Her career in Haematology began as a senior house officer at King’s College Hospital, following which she was accepted on the Guy’s and St Thomas’ NHS Trust Specialist Registrar Rotation in 2009. She obtained her certificate of completion of training in 2014, and thereafter took on consultant haematologist positions for a period of two and a half years at both Guy’s and St Thomas’ and King’s College Hospitals.

Dr Mwirigi has a passion for haematology and always planned to practice haematology in her country of birth, Kenya. Since moving back in December 2016, she has engaged with haematopathologists and clinical haematologists in the region, and is involved collaborative ventures aimed at improving the quality of haematology services in Kenya. She was a key member of the scientific committee which organised the Haematology and Oncology Society of Africa 3rd inaugural conference held in Nairobi in August 2017.
