Research interests

Prof. Malliaras' research is on bioelectronics. He leads a group of scientists, engineers and clinicians who study the fundamental processes that take place at the abiotic/biotic interface and develop better tools for healthcare. Research themes include the development and translation of implantable and wearable devices that interface with electrically active tissues, with applications in neurological disorders and brain cancer.

George Malliaras is the Prince Philip Professor of Technology at the University of Cambridge. He received a BS in Physics from the Aristotle University (Greece) in 1991, and a PhD in Mathematics and Physical Sciences, cum laude, from the University of Groningen (the Netherlands) in 1995. After postdocs at the University of Groningen and at the IBM Almaden Research Center (California), he joined the faculty in the Department of Materials Science and Engineering at Cornell University (New York) in 1999. From 2006 to 2009 he served as the Lester B. Knight Director of the Cornell NanoScale Science & Technology Facility. He moved to the Ecole des Mines de St. Etienne (France) in 2009, where he started the Department of Bioelectronics and served as Department Head. He joined the University of Cambridge in 2017.

Prof. Malliaras' research on organic electronics and bioelectronics has been recognized with awards from the New York Academy of Sciences (Blavatnik Award for Young Scientists), the US National Science Foundation, and DuPont, and with an Honorary Doctorate from the University of Linköping, Sweden. He is a Fellow of the Materials Research Society and of the Royal Society of Chemistry, and serves as a Deputy Editor of Science Advances. He is the Director of the EPSRC IRC in Targeted Delivery for Hard-to-Treat Cancers.

Prof. Malliaras is a co-author of 300+ publications in peer-reviewed journals that have received over 42,000 citations. His h-index is 111 (google scholar, 02/23).
