In Chapter 2 of 21 in her 2010 interview with Erik Michielsen, global health consultant Gabrielle Lamourelle details her transition from biology to sociology majors while studying at University of California at Berkeley. Lamourelle finds the biology track over-competitive for the wrong reasons, specifically medical school preparation instead of passion for biology. Lamourelle decides to shift focus to a major, sociology, with a more collaborative, teamwork driven culture. Lamourelle graduated with a BS in Sociology from University of California at Berkeley and a Masters in Public Health (MPH) in Sociomedical Sciences from the Mailman School of Public Health at Columbia University.
