Julian is Reader in Mathematics at the University of Edinburgh.

He has decades of experience in developing high performance computational techniques for the solution of linear programming problems.

Disseminated via prize-winning academic papers, his expertise has also yielded consultancy relationships with commercial companies both large and small.

Eventually, this research led to and the development of the world's best open source linear optimization solver, HiGHS.

Geoffrey is a world-renowned expert in automated planning of complex schedules and the AI algorithms to solve them.
In 2006, he created the open source solver OptaPlanner (now known as Timefold Solver).

He has been working on it ever since, including 9 years for IBM Red Hat. In 2022, he created an open core company around it.

Timefold is now the go-to platform to empower software builders to route vehicles, schedule jobs or assign employees optimally through ready-made models.

Ted is a professor in the Department of Industrial and Systems Engineering (ISE) at Lehigh University, director of the Laboratory for Computational Optimization Research at Lehigh (COR@L), and an INFORMS Fellow.

He is co-founder of the COIN-OR Foundation, a non-profit promoting the development of open source software for operations research, chairing its Technical Leadership Committee and sitting on its Strategic Leadership Board.

He has developed and manages a wide range of open source projects hosted in the COIN-OR open source software repository.
