My research activities in the Department of Civil and Environmental Engineering are in mechanics, materials, and structures. At WPI, my favorite teaching aspect is working one-on-one with graduate and undergraduate students on research projects. I like to excite students’ curiosity toward discoveries and creative scientific advancements. In our research group, we focus on the fundamental principles that control the behavior of materials in engineering and biology at multiple scales. I am particularly interested in 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, we have created a new paradigm in self-healing concrete using an enzymatic mechanism. Using the same mechanism, we have now produced a Carbon-Negative Enzymatic Construction Material (ECM), which sequesters 18 lbs of CO2 per cubic yard in comparison to concrete which emits around 700 lbs of CO2 per cubic yard. ECM also holds the record in compressive strength as a carbon-negative alternative structural material at around 15 MPa.  I encourage you to see the details of our research activities on my group's website.

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.
