Chris J. L. Doran is a physicist

Physicist

A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

, Director of Studies in Natural Sciences for Sidney Sussex College, Cambridge

Sidney Sussex College, Cambridge

Sidney Sussex College is a constituent college of the University of Cambridge in England.The college was founded in 1596 and named after its foundress, Frances Sidney, Countess of Sussex. It was from its inception an avowedly Puritan foundation: some good and godlie moniment for the mainteynance...

. He founded Geomerics

Geomerics

Geomerics is a software company based in Cambridge, UK, that specialises in creating lighting technology for the video game industry.The company's main product is Enlighten, software code that calculates indirect lighting in real time for live action games running on systems such as the...

, 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

Royal Society of Edinburgh

The Royal Society of Edinburgh is Scotland's national academy of science and letters. It is a registered charity, operating on a wholly independent and non-party-political basis and providing public benefit throughout Scotland...

.

He took a break from academics in 2005, and he subsequently founded Geomerics. In his own words, he had been looking for a challenge and for other ways to win people over to geometric algebra.

His research interests relate to applied mathematics

Applied mathematics

Applied mathematics is a branch of mathematics that concerns itself with mathematical methods that are typically used in science, engineering, business, and industry. Thus, "applied mathematics" is a mathematical science with specialized knowledge...

 and theoretical physics

Theoretical physics

Theoretical physics is a branch of physics which employs mathematical models and abstractions of physics to rationalize, explain and predict natural phenomena...

, in particular quantum theory

Quantum theory

Quantum theory may mean:In science:*Quantum mechanics: a subset of quantum physics explaining the physical behaviours at atomic and sub-atomic levels*Old quantum theory under the Bohr model...

, gravitation

Gravitation

Gravitation, or gravity, is a natural phenomenon by which physical bodies attract with a force proportional to their mass. Gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped...

, geometric algebra

Geometric algebra

Geometric algebra , together with the associated Geometric calculus, provides a comprehensive alternative approach to the algebraic representation of classical, computational and relativistic geometry. GA now finds application in all of physics, in graphics and in robotics...

 and computational geometry

Computational geometry

Computational geometry is a branch of computer science devoted to the study of algorithms which can be stated in terms of geometry. Some purely geometrical problems arise out of the study of computational geometric algorithms, and such problems are also considered to be part of computational...
