Antonis was born in 1990 in Thessaloniki, Greece. He received his B.Sc. in Physics from Aristotle University of Thessaloniki in 2011, with a specialization in solid state physics. As an undergraduate student, he conducted research in thin film characterization using X-ray absorption spectroscopy in the University of Bologna, Italy, and the European Synchrotron Radiation facility in Grenoble, France. He earned his M.Sc. in Nanotechnology and Regenerative Medicine from University College London, United Kingdom, in 2013, where he conducted research on positron emission mammography and magnetic resonance imaging using superparamagnetic iron oxide nanoparticles as contrast agents. He obtained his Ph.D. in Bioengineering from Imperial College London, United Kingdom, in 2017, for his work on controlling microbubble dynamics in ultrasound therapy. During his Ph.D., he developed multiple techniques in the field of therapeutic ultrasound, including rapid short-pulse therapy, Doppler passive acoustic mapping, and optical methods for investigating microbubble motion during ultrasound exposure. He is currently working as an associate research scientist in the Ultrasound Elasticity Imaging Laboratory. He has received multiple awards and serves as a reviewer for more than 20 international peer-reviewed journals. He has mentored over 60 high-school, undergraduate and graduate students in their research projects and has been involved in outreach events promoting scientific research to the community. His research interests include targeted drug delivery using ultrasound, microbubble dynamics in ultrasound therapy, ultrasound therapy monitoring, and clinical translation of therapeutic ultrasound.
