Benjamin Tham is a PhD candidate in the Department of Mechanical & Industrial Engineering at the University of Toronto. He received his MSc in Physics & Engineering in Medicine from University College London (2015), and his BSc (Hons) in Physics, with Minors in Philosophy and Biophysics, from National University of Singapore (2014). Prior to his PhD, he worked as a medical physicist at National Cancer Centre Singapore (NCCS), where he ensured radiotherapy treatment quality and radiation safety.

Benjamin’s research focuses on optimization methods for advanced brain tumour treatment in Gamma Knife radiosurgery machines, including dose painting from functional imaging analysis and continuous path dynamic treatment. This work is in collaboration with Princess Margaret Cancer Centre and Elekta AB. He has also been part of a multi-organization team to develop an agent-based simulation model of COVID-19 disease spread in a heterogeneous, geospatial population. Outside of research, he volunteers at Free Geek Toronto, a nonprofit centered on improving digital inclusion, and he was a teaching assistant for Engineering Strategies and Practice, a foundational course teaching design and communication.
