S. John Hogan is a professor of Applied Mathematics and leader of the "Applied Nonlinear Mathematics Group" in the Department of Engineering Mathematics, University of Bristol

University of Bristol

The University of Bristol is a public research university located in Bristol, United Kingdom. One of the so-called "red brick" universities, it received its Royal Charter in 1909, although its predecessor institution, University College, Bristol, had been in existence since 1876.The University is...

. He is known for his work in numerous applications of non-linear dynamics including water waves liquid crystal

Liquid crystal

Liquid crystals are a state of matter that have properties between those of a conventional liquid and those of a solid crystal. For instance, an LC may flow like a liquid, but its molecules may be oriented in a crystal-like way. There are many different types of LC phases, which can be...

Hogan is principal investigator on several large EPSRC grants, in 2008 totalling around £6M - an unusually high total for a UK mathematician. These include the "Bristol Centre for Complexity Sciences", the "Bristol Centre for Applied Nonlinear Mathematics", "Applied Nonlinear Mathematics: Making it Real" and
