Upon completing her PhD, Bizios accepted a faculty position in the Biomedical Engineering department of Rensselaer Polytechnic Institute (RPI) in 1981.[4] During her tenure at RPI, Bizios found a way of using electricity to grow artificial bones and make them deposit proteins and calcium. She did this by using carbon nanotubes-tubular molecules as electrical conductors to deliver electricity to bone-forming rat cells deposited on a piece of polymer.[5] In 1999, Bizios was elected a Fellow of the American Institute for Medical and Biological Engineering for "outstanding contributions in biomaterials aspects of tissue engineering and for excellent service in biomedical engineering education."[6] The following year, she was inducted as an International Fellow of Biomaterials Science and Engineering of the International Union of Societies for Biomaterials Science and Engineering.[7] In 2002, she took a sabbatical leave to serve as the Chalmers Jubileums Professor at Chalmers University of Technology in Göteborg, Sweden.[4]
Bizios left RPI in 2006 to become the Peter T. Flawn Distinguished Professor of Biomedical Engineering at the University of Texas at San Antonio (UTSA).[3][7] During her first three years at UTSA, Bizios was also the Hunter Distinguished Lecturer at Clemson University and the Myrle E. and Verle D. Nietzel Visiting Distinguished Faculty Lecturer at the University of Kentucky.[8]
