A/Prof Mikael Hartman has been practising in Singapore since 2009 and is originally from Stockholm, Sweden where he received his training at Karolinska Institute. That is also where he received his board certification in General Surgery in 2005. Having completed his doctoral studies in the field of epidemiology in 2007, he specializes in the field of breast cancer etiology and prognostification as well as inheritance of cancer prognosis. He has been a co-recipient of the Breast Cancer Concept Award, US Army, in 2002 and 2006.
He heads a research group of more than ten members including three PhD students and is leading the development of the Singapore Breast Cancer Cohort and the Singapore-Malaysia Breast Cancer Working Group and the Breast Cancer Prevention Programme in the Saw Swee Hock School of Public Health (SSHSPH). The research has been published in Lancet Oncology, Journal of Clinical Oncology, Breast Cancer Research, British Journal of Surgery, European Journal of Cancer etc. He serves as the Deputy Director of the Initiative for Research and Innovation in Surgery – NUHS, the Research Director of the University Surgical Cluster Research Committee – NUHS, the Head of Surgical Clinical Epidemiology Unit - NUHS, Deputy Head of Breast Services in Department of Surgery – NUH and a member of SSHSPH Senior Management Committee and Faculty Promotion and Tenure Committee. 

He is a father of 3 children with a keen interest in skiing, hiking and mountain biking. In 2014 he made an effort to create awareness for breast cancer and research by riding a motorcycle from Singapore to Sweden.
