Dr. Kalache, physician, PhD. in Epidemiology from the University of London, is one of the very earliest voices to articulate the global nature of population aging, together with the potentialities and the risks through inaction inherent within it. He pioneered the concept of "active aging" and developed the Global Movement on Age-Friendly Cities at the World Health Organization (WHO) as head of the Ageing and Life Course Program from 1995 to 2008. In 2008 he relocated to the USA where he assumed a new position as Senior Policy Adviser on Global Ageing to the President at the New York Academy of Medicine (NYAM). He simultaneously commenced the role of Global Ambassador for the London based HelpAge International the largest and most influential worldwide civil society organization on aging. Currently, Dr. Kalache co-chairs the International Longevity Center (ILC) Global Alliance, a multinational consortium of seventeen autonomous think tanks on policies for aging, and presides over the ILC Brazil. Dr. Kalache's contributions toward the shifting of the traditional paradigms in the field of aging are widely acknowledged on the global stage, as academic, international civil servant, and advocate.
