My name is Charles Weijer (pronounced VEY-er). I am a bioethicist and professor at Western University in London, Canada who specializes in research ethics.


Together with an interdisciplinary team of colleagues and trainees, I explore ethical issues in randomized controlled trials, COVID-19 human challenge studies, and organ donation.
