### Byrne Postdocs

The Byrne Postdoctoral Fellows were established as part of the Byrne Fund for Financial Mathematics and Risk Management. The fund was created to honor John J. (Jack) Byrne, through a donation by his wife Dorothy. Jack Byrne received a Masters of Actuarial Science from the UM Mathematics Department in 1959. He was a student and good friend of long-time actuarial program director Professor Cecil Nesbitt. Byrne had a long and distinguished career in the industry, including serving as Chairman and Chief Executive of GEICO for many years, head of Fireman's Fund Insurance, and founder of White Mountains Insurance Group. Jack passed away in 2013, and Dorothy is still actively supporting this cause.

### James Van Loo Postdocs

In 2014, the Department of Mathematics received a gift from the estate of alumnus James Van Loo (BS 1967) that supports various initiatives in the area of Applied Mathematics, including the Van Loo Postdoctoral Fellowships. Mr. Van Loo began his career at General Electric in Florida, where he worked on high performance graphics. He joined Sun Microsystems in 1985 as a software engineer in internet standards and graphics, and eventually retired from Microsoft in 2009, where he worked on internet standards. Mr Van Loo was an innovator in the field, and held several patents related to computer graphics and internet standards.
