My field of interest is bio-inspired materials and the unique mechanics involved in biomaterials such as bone and nacre.
The biomaterial, nacre, consists of 95% bio-ceramics and 5% organic matrix. The bio-ceramic has a hexagonal structure from the top-down cross section and a brick and mortar structure from the front cross section, with the mortar being the organic matrix.
The organic matrix is a solution of proteins, keratin and some other natural polymers. The combination of all these organic polymers have significant contributions to the energy dissipation upon applied stress to the nacre.
All in all, mother nature has developed it’s structures to the most stable conformation in order to simply exist.
This field enables us to learn from nature and apply it’s art of survival in stable yet efficient material configurations. We can use this knowledge to build advanced materials for high technology spacecrafts, armors, building blocks and many other applications.
I am a PhD student at Worcester Polytechnic Institute in the field of materials and currently working on the mechanics of nacre. I employ molecular biology, molecular dynamics using quantum mechanics principals, finite element analysis or continuum mechanics, polymer dynamics and related tools to study natural conformations. I also use macro scale tools and principals such as additive manufacturing and laboratory equipment for testing and manufacturing test specimens.
I am interested in discussing new ideas and discovering new opportunities to improve my knowledge. Please feel free to contact me.
