Dr. Brockwell's research interests include stochastic differential equations, Markov chains, time series, and control theory. He is particularly interested in the study of stochastic control problems in which system descriptions are incomplete and/or inaccurate, and in the development of new models explaining market price behavior. Dr. Brockwell has published articles in such journals as the Annals of Statistics, Journal of Time Series Analysis, SIAM Journal on Control and Optimization, and Journal of Computational and Graphical Statistics. In 2007 he left academia to join a small startup hedge fund as a quant in New York city, where he developed and managed a portfolio of quantitative trading algorithms.
