About Me

Hello! I am Tifani, a Postdoctoral Fellow at King Fahd University of Petroleum and Minerals, Saudi Arabia. I am an economist specializing in applied spatial econometrics, regional economics, labor markets, and causal inference. My research investigates the socio-economic impacts of infrastructure development, labor market dynamics, and financial inclusion. Methodologically, I currently leverage advanced spatial modeling to analyze geospatial and large-scale panel data. Some of my works have been published in reputable peer-reviewed international journals, such as Economic Modelling, Transportation Research Part A: Policy and Practice, and Bulletin of Indonesian Economic Studies.
