Akhlesh Lakhtakia's research focuses on electromagnetic fields in complex materials, such as sculptured thin films, chiral materials, bianisotropy and industrially scalable bioreplication, an emerging form of engineered biomimicry applied to harvesting of solar energy and pest eradication. His technique for visualization of latent fingerprints was covered in the NOVA documentary series "Forensics on Trial".
