Dr. Kiani’s general areas of expertise include failure analysis, materials characterization with an emphasis on nano and micro- scale techniques, as well as macro- and nano-scale mechanical properties of materials, for both room- and high-temperature applications. She has experience in a wide range of materials applications such as failure analyses associated with oil and gas drilling, mechanical behavior and product development of materials, and deformation/failure of composite and ultra-high temperature ceramic materials in aerospace and hypersonic flight applications.

Prior to joining Exponent, Dr. Kiani conducted her Ph.D. dissertation work at the Lawrence Berkeley National Laboratory, national center for electron microscopy (NCEM) where she examined the mechanical behavior and deformation mechanism of sub-micron ultra-high temperature ceramics (ZrC, SiC, TaC) in situ transmission electron microscopy (TEM). Dr. Kiani has performed extensive amounts of microstructural characterization and material evaluation using optical microscopes (OM), scanning electron microscopes (SEM), focused ion beam microscopes (FIB), and transmission electron microscopes (TEM), as well as mechanical testing including compression, tension, bending, fatigue, impact, wear using MTS, Intron and custom-made test units. As a research engineer at Kennametal Inc. from 2005–2008, Dr. Kiani was in charge of the mechanical testing laboratory including operation, maintenance, training, design of new field-related experiments, and data interpretation of different mechanical testing techniques and equipment. She also worked as a process engineering intern at Maxim Integrated where she was involved with gold-silicon bonding issues and process optimization for MEMS production in the clean-room.

Additionally, Dr. Kiani has fulfilled her interest in teaching at UCLA in various courses including introduction to scanning and transmission electron microscopy, introduction to materials science and reliability, maintainability and system engineering as a teaching assistant. She was also a science instructor and a mentor for art-sci summer camp and SMARTS program at UCLA.
