Before PhD:

• I studied Operations Research all my life – needless to say, it’s a fascinating field! It’s an amazing field to be in if you love solving problems and putting pieces of the puzzle together (and especially if you enjoy working with people). Take a look at the INFORMS article on Analytics/Operations Research Career. I received my B.S. from UC-Berkeley (Go Bears!) and M.S. from Columbia University, both in Industrial Engineering and Operations Research.

• I worked at a number of organizations, namely @ Spire Health (health data science), UC-Berkeley Registrar’s Office (project management), Disneyland Resort (facilities & operations services), Christiansen Capital Advisors LLC (gaming and leisure industry), and Columbia Business School (technology in higher education).

• I studied Chinese (pretty intensely) in college. With much gratitude to the Huang Scholars Program, I was able to spend two summers @ Beijing during my college years.
