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;
- Exercise solutions for the book;
- My blog on financial risk management.
I continue to accept a limited number of consulting engagements. These generally relate to high-level risk management strategy, addressing organizational issues related to risk management, or risk measure analytics. Please contact me, if you have a need.
People involved in financial risk management know of me. I worked in the industry full-time for many years before switching to academia. I teach in the Department of Applied Mathematics at Wentworth Institute. I also tutor mathematics to promising young students. My risk-related research continues.
