I have worked as an equity option market maker and prop trader on the NYSE ARCA exchange floor since Feb. 2008. I'm now upstairs (off floor) and visit the floor a few times a week. Prior to working on the exchange floor I worked as a structurer on the Countrywide trading desk and before that as the Director of Client Services and Research for the quant modeling firm Audit Integrity. I have a Masters degree in Financial Mathematics from Stanford University. I also have an MBA in finance and an undergraduate degree in quantitative economics with an area of focus in mathematics. I write for thestreet.com's (TSCM) Option Profit premium service on behalf of Livevol. The posts are published on Yahoo! Finance and Fidelity.com weekly after the premium TSCM users have had a chance to read them first. I'm interviewed by Bloomberg and occassionally through re-pubs in the SF Chronicle and Miami Herald.
