Dr David Alexander Gregory is a Post-Doctoral Research Associate to Prof Ipsita Roy at the University of Sheffield in the Department of Materials Science & Engineering.
Dr David Alexander Gregory previously worked as a PDRA to Dr Zhao at the University of Sheffield in the Department of Chemical and Biological Engineering.
Research
My research is concerned with applied inkjet printing, which contributes to areas as diverse as tissue engineering, printed electronic devices and 3D scaffold printing of e.g. swimming devices for biomedical applications. Inkjet printing is an additive manufacturing technique. I am an enthusiastic researcher, who enjoys research and supervising / mentoring. I particularly aspire to create new projects that combine several different discipline areas.
It is my future vision to develop new versatile biomaterials and the technologies needed to produce these in order to develop better 3D scaffold systems for use in biomedical applications e.g. regenerative tissue engineering as well as biosensing for disease and toxin monitoring. These address key healthcare challenges as well as environmental monitoring, challenges our society urgently needs to address. Another aspect in line with this is that I am very interested to investigate effects of electronic signals and stimulations of cells.
