A PhD epidemiologist by training, he uses photography to explore patterns of change among human populations, focusing on architecture as evidence of often-invisible social, environmental, and economic processes. Mark was awarded an Individual Artist Fellowship from the DC Commission on the Arts and Humanities in 2014, and he was previously selected a Finalist for the Sondheim Prize in 2011 and a Semi-Finalist for Critical Mass in 2012. His work has been featured at galleries in Washington DC and in Spain and appears in the DC Art Bank and numerous individual collections. His exhibit ‘Once Upon a Time in Almería’ was shown at the Embassy of Spain in 2012 and has since traveled to Miami and other locations. In June 2014, his first photobook ‘Carabanchel’ was published, including photographs and text about the infamous Franco-era prison in Madrid.
