Curriculum Vitae Talita Greyling

About Prof Talita Greyling

I specialize in well-being economics and quality of life studies and have a keen interest in fourth industrial revolution applications. I have developed the “Happiness Index” using Big Data and machine learning and am the director of the Gross National Project (, which continuously research and develop the index. The project received the Vice Chancellor’s Distinguished Award for Innovation, and the data has been accepted as official statistical data by the New Zeeland statistical office.

Talita is the author of numerous articles in multi-disciplinary and economic journals in top-ranked academic journals (impact factor of 3+). Since 2020 she has been actively involved in COVID-19 research projects. She is the associate editor for Pioneers in Quality of Life Theory and Research for the Journal of Applied Research in Quality of Life (impact factor 3.2) and a co-editor for economics in the Journal of Happiness Studies (impact factor 3.9). She is the Vice-President (Membership) of the International Society for Quality-of-Life Studies and is a Research Fellow of the Global Labor Organization (GLO). Talita is involved in several international collaborations related to well-being research.

I am fortunate to often act as a keynote speaker at events, this has included a TEDx talk, and I often participate in radio shows, television shows and podcasts.
