Professor Rahbar studies the fundamental principles that control the behavior of materials in engineering and biology at multiple scales particularly the bioinspired design of materials and structures. In this field, studying biological materials leads to the design of high-performance materials and structures. For example, Prof. Rahbar's lab has created bioinspired dental ceramic crowns that last longer than the current dental crowns; studied the fracture properties of bamboo as a sustainable structural material, and researched the fracture and fatigue of materials and structures in ceramics. His team was also involved with the repair of the Adam statue at The Metropolitan Museum of Art in New York. Some of his most recent work involves developing self-healing concrete and a sustainable concrete substitute.

Science Daily
Developing a sustainable concrete substitute

Science Daily covered the continued collaboration between Professor Suzanne Scarlata and Associate Professor Nima Rahbar to develop their Enzymatic Construction Material – a sustainable, low-cost replacement for concrete that can also heal itself. Scarlata and Rahbar recently received a nearly $700,000 grant from the National Science Foundation to refine the material, explore its ability to repair cracks in glass, and create educational programs for girls in Worcester and Nigeria.

BBC Earth
Is it possible to heat our homes without heating our planet?

BBC Earth featured the self-healing concrete developed by Associate Professor Nima Rahbar and Professor Suzanne Scarlata in an episode about climate-friendly ways to heat residential homes. The self-healing concrete uses an enzyme found in red blood cells to heal itself, thereby filling cracks before they cause larger structural issues.
