Irena was raised in Medan, North Sumatra. She moved to Bogor in 2010 to pursue higher education and completed her bachelor’s degree in Food Technology at IPB University in 2014. After graduation, she worked as a research assistant in the Department of Food Science and Technology at the same university.
