Sahar Jafari, Ph.D.

Accomplished senior materials scientist with a track record of leadership and innovation in developing leading edge technologies and materials across industries including biomaterials, magnetic alloys, ceramics and pharmaceuticals. My projects have led to patents in the areas of materials science xxxx I enjoy collaborating with cross-functional teams, and respond especially well to fast-paced and goal-oriented environments.

• Designed and formulated novel magnetic alloys that improved the efficiency of Toyota hybrid propulsion systems.
• Developed manufacturing processes for Toyota by analyzing microstructure-physical properties of magnetic materials, contributing to advancements in automotive propulsion technology.
• … patents submitted as first inventor on creative techniques to synthesize magnetic materials with complex structure and materials with novel magnetic properties.
• Formulated novel liposomal materials for targeted drug delivery for US army.
• Led the design of manufacturing of two sterile injectable drug products at a pharmaceutical setting in small scale and 95% scale up, integrating principles of materials characterization, statistical analysis, and materials manufacturing. The successful application of these methodologies resulted in the filing of 2 FDA ANDAs.
• Led multi departmental team in a successful redevelopment of a product with improvement in nano materials characterization performance of the product
