**Chris J. L. Doran** is a physicist, Director of Studies in Natural Sciences for Sidney Sussex College, Cambridge. He founded Geomerics, and is its Chief Operating Officer.

Doran obtained his Ph.D. in 1994 on the topic of *Geometric Algebra and its Application to Mathematical Physics*. He was an EPSRC Advanced Fellow from 1999 to 2004. In 2004, he became Enterprise Fellow of the Royal Society of Edinburgh.

Doran has been credited, together with Anthony N. Lasenby, Joan Lasenby and Steve Gull,^{[1]}^{[2]} for raising the interest of the physics community to the mathematical language and methods of geometric algebra and geometric calculus. These have been rediscovered and refined by David Hestenes, who built on the fundamental work of William Kingdon Clifford and Hermann Grassmann.^{[3]} In 1998, together with Lasenby and Gull, he proposed the gauge theory gravity.^{[4]}

He took a break from academics in 2005, and he subsequently founded the software company Geomerics, making use of his knowledge of mathematics. His research interests relate to applied mathematics and theoretical physics, in particular quantum theory, gravitation, geometric algebra and computational geometry.

Doran has authored more than 50 scientific papers.^{[5]}
