Know your risk.
Hello! I am Professor Glyn Holton. My research field is the mathematics and foundations of risk. This website is about that research.
If you are looking for something specific, it is likely one of these:
- My landmark paper Defining Risk;
- My book on value-at-risk—the second edition is free online; or
- Exercise solutions for my book.
On this site, you will also find my blog, a link to my other publications, and more.
People involved in financial risk management for a while know of me. I worked in the industry for many years before switching to academia. I taught mathematics at Wentworth Institute for a number of years while continuing my research. I recently retired from the classroom and now tutor mathematics. My risk-related research continues.
