Email: hdarge@uwaterloo.ca

Haile received his MSc in Medicinal Physiology from Addis Ababa University, School of Medicine in 2014. He joined Prof. Hsieh-Chih Tsai’s lab at the National Taiwan University of Science and Technology (Taiwan Tech) in 2017 and completed his PhD in 2020. After graduation, he continued his postdoctoral research work in Prof. Hsieh-Chih Tsai’s lab until 2022. His research work focused on the preparation of polymeric biomaterials (injectable smart hydrogels and nanocarriers, microspheres and microneedles) for controlled drug delivery in cancer treatment, wound dressing, and for 3D cell culturing. He has authored 28+ peer-reviewed research articles in the area of drug delivery for cancer treatment. Currently, he is a postdoctoral research fellow at CORE and his research work is focusing on developing biomaterials for ocular drug delivery and in vitro eye models using 3D printing technology.
