Atadila Belva Ganya – MSc student

Hi, I am Belva! I was born in Bekasi, Indonesia. I completed my Bachelor’s degree in Biomedical Engineering at the Bandung Institute of Technology in 2024, and am currently pursuing my Master’s in Biomedical Engineering at TU Delft, from 2025. Ever since my bachelor’s, I’ve always been interested in rehabilitation engineering, where I did my bachelor’s thesis on mirroring gloves for physical therapy in individuals with Cerebral Palsy (CP), and later worked on arm prostheses, both with the start-up Karla Bionics. That experience showed me how crucial the body-device interface is for monitoring and stimulation, sparking my fascination with the nervous system’s role in active implantable medical devices. Motivated to make these devices safer and better tolerated for long-term use in the human body, I joined the ReBooT group under Dr. Achilleas Savva, where I will work on the conductivity of PEDOT-based electrodes for my master’s thesis, building on my current internship on their stability at the Neural Waves Lab, Ghent University.
