I am a social impact entrepreneur, executive coach, and investor focused on developing and scaling new approaches to transforming climate, health, and education outcomes, particularly in emerging markets. I currently lead climate-related initiatives and investments for a number of philanthropies and serve as an executive coach for a range of rapidly growing climatetech companies.I previously founded and led three rapidly growing ventures in Africa and continue to serve on the board of two of them. The largest of those enterprises, Nova Pioneer, is a high-quality, accessible school network that has scaled to 16 schools and more than 800 staff across the continent and was recognized with a Transformational Business Award by the Financial Times. I spent over a decade of experience in leadership in global health and development, most of that time as the Executive Vice President for Global Programs at the Clinton Health Access Initiative (CHAI). At CHAI, I led the design and execution of large-scale programs to reduce child mortality and transform health systems in more than 20 countries and managing the organization’s relationships with major global institutions. I also served as the Chair of the Market Dynamics Committee of the Board of the Global Fund to Fight AIDS, Tuberculosis, and Malaria, guiding the development of improved strategies to better leverage the institution’s $22 billion of investments to shape health product markets. I am the author of more than 20 scholarly articles on global health published by Science, Cambridge University Press, the Journal of the American Medical Association, the British Medical Journal, and The Lancet.
