Mark Ian Wallace FRSC is a Professor of Chemistry at King's College London. His research group is interested in understanding the underlying mechanisms that govern how membrane proteins function; by combining new methods in optical microscopy with new ways to generate artificial mimics of the cell membrane.

Mark studied Chemical Physics as an undergraduate at the University of Bristol, followed by a PhD in Chemistry at the University of Cambridge under the supervision of Professor David Klenerman. He was awarded the 2002 Gregorio Weber International Prize in Biological Fluorescence for this work. Mark then spent 2 years as a postdoctoral fellow at Stanford University, working with Professor Richard Zare. He returned to the U.K. in 2002 to undertake a second postdoctoral position at the National Institute for Medical Research with Dr Justin Molloy, before moving to Oxford in 2005 as a Royal Society University Research Fellow. He was subsequently appointed as a University lecturer and fellow of Wadham college in 2006. He remained as an Associate Professor at Oxford until 2016 when he moved to King's.

In 2009 Mark was appointed to the steering committee of the British Biophysical Society. Patents arising from his work have also been licensed in the U.K. Mark has also been active in raising awareness of his group's research beyond the lab, including video podcasting and participation in the 2014 "I'm a scientist get me out of here" competition. He was awarded the RSC Norman Heatley Award in 2015 in recognition of his work.
