Andrew has written the first biography on Gen. John Shalikashvili, chairman of the U.S. Joint Chiefs of Staff (1993–1997).

In 8 years of research he traveled over 30,000 miles to 30 cities, 12 states, 3 countries, and 2 continents; accessed 2 restricted Shalikashvili archives; and interviewed well over 300 people, from Shalikashvili and his family and childhood friends to President Bill Clinton, Gen. Colin Powell, Sec. of Defense William Perry, Sec. of State Madeleine Albright, and other leaders from the 1990s.

His research was partially funded by a George Marshall Foundation Baruch Fellowship Award. In both 2014 and 2016 he was one of three finalists for the Biographer International Organization's (BIO) Hazel Rowley Prize for best proposal for a first biography.
