I will be working in the SEC's new division of Risk, Strategy and Financial Innovation as Senior Policy Adviser to the Director.  Here is a 
brief article and the 
SEC announcement. We are facing a critical time  for defining the future of the financial system; an opportunity for financial reform that comes only once in a generation (if that), and I am excited to be part of this. 
I will still be able to write posts from time to time, but obviously with limits on topics and with appropriate disclaimers.  How much free time I have to do so, though, remains to be seen.
I won't be able to publish comments for this post related to the SEC.
