I have 30 years of experience, and specialize in the field of finance with specific knowledge in the areas of trading, derivatives and risk management. I have published on such topics as intraday behavior of options and futures, risk managment and hedging and portfolio management. I have overcome the wide difference between academic research and practical importance with my research, publications, and teaching. I research interesting issues in trading and investment decision making and then communicate those results so that non-academics can understand them. I believe in applying ideas rather then developing theoretical models. Specific areas of recent work include trading issues in futures and options, volatility products (VIX, VIX futures, VIX options), options on ETFs, market crashes, and price behavior in chaotic markets.
