Over the past fifteen years spent documenting some of the world’s most brutal wars Marcus has focused on campaigning against human rights abuses. He has been documenting these issues for Human Rights Watch and he is a contributing photographer for National Geographic Magazine.
Using his background in business and economics, he researches the sources of financing driving the conflicts, which usually leads to the mines, and the armed networks linked to them. Marcus covered the wars in Sierra Leone, Liberia, The Democratic Republic of Congo, Central African Republic, Somalia, Chad and Darfur, Kashmir and Georgia.
Since 2000 Marcus has worked extensively in eastern Democratic Republic of Congo documenting a war funded by the extraction of the minerals used in every day electronic products. Marcus has partnered with international advocacy groups Human Rights Watch and the Enough Project to engage US and European politicians and multinational companies to change government policy and working practices.
Over the past three years Marcus has been working in the Central African Republic documenting the conflict in the region. The work from Central African Republic won the Amnesty International Award for Media in 2014 and the prestigious Robert Capa Gold Medal from the Overseas Press Club of America in 2015.
