Before joining UNA-UK, Carver ran the Sri Lanka Campaign for Peace and Justice, a human-rights NGO that advocated for peace in Sri Lanka based on justice and accountability for crimes committed in the civil war. Before that, he worked in local government and as a researcher and writer. He conducted field research in Pakistan, Sri Lanka, Afghanistan, Tajikistan, Israel and Palestine. In addition, Carver has been published in Asian Affairs and Himal Magazine; is a trustee of Support a Survivor of Torture, a charity providing psychosocial support to torture survivors living in Britain; and remains a member of the Sri Lanka Campaign for Peace and Justice's council of advisers.
Carver has a master's degree in Asian politics from the School of Oriental and African Studies (SOAS) and started a Ph.D. at Kings College London on the effects of urbanization on political violence in Pakistan. This research was later turned into a series of articles.
