Tom and the team members are portfolio managers for multi-manager and factor solutions offered by the firm, including US, global, non-US, regional, and hedge fund strategies. Tom also spearheads analyzing key trends and factor biases across equity markets and plays an integral role in our technology and fiduciary oversight processes, serving on a number of our investment review and risk advisory committees, including Equity Review Group I.

Prior to joining the firm in 2009, Tom spent nine years at FactSet Research Systems Inc. (2001 – 2009), where he served as vice president. He also worked at Quantitative Analytics (2007 – 2009) and served as a quantitative specialist (2003 – 2007) and a consultant (2001 – 2003).
