Vatana Chea

Dr. CHEA Vatana has joined CamTech as a founding member in 2021. Prior to that, he worked as a researcher at the Cambodia Development Resource Institute (CDRI), a policy think-tank. He holds a master degree in private law from the Royal University of Law and Economics, Phnom Penh, Cambodia, and a master and Ph.D degree in demography from Chulalongkorn University, Bangkok, Thailand. He was also a doctoral fellow at the Centro Studi di Politica Internazionale and at Roma Tre University, Rome, Italy. Dr. Chea is currently attending a master degree of applied science in data, economics, and development policy at the Massachusetts Institute of Technology (MIT). His research interest includes population projection, migration and development, human capital development, and economics of household. He has authored and co-authored more than a dozen peer-reviewed scientific articles including book chapters and journals in ISI and SCOPUS database.
