Brief Description of Research Interest :

As a postdoctoral fellow at the University of Victoria I am working on developing a low-cost technique for fabrication of large-size flexible transparent electrodes, an essential layer in optoelectronic devices including solar cells and touchscreens. I have a Ph.D. in Mechanical Engineering and M.Sc. in Materials Science Engineering with 11 years of academic and industrial experience in leading design and manufacturing projects.  My research interest includes nanofabrication and investigating the properties of nano and micron-size structures for applications such as solar cells, fuel cells, biosensors and touch screens. Being able to manipulate small-size structures, we can use their extraordinary electrical, optical and chemical properties to fabricate devises with very high sensitivity, fast chemical reactivity, or tunable electrical and optical properties.  During my Master’s program(2005 – 2008) I worked on fabrication of thin-film solar cells by electrochemical technique. My research was honored in an annual competition at Shiraz University-Iran and registered as an innovation for developing a new and creative method of fabricating cost-effective solar cells. Pursuing my Ph.D. degree, I joined Dr. Bhiladvala’s laboratory (Nanoscale Transport, Mechanics& Materials (NTMM)) at the University of Victoria in 2011. Knowing the importance of clean energy and the obstacles in increasing the efficiency of solar cells, I proposed a creative method of fabricating transparent electrodes to decrease the fabrication cost and improve the properties of the transparent electrodes. I also demonstrated a framework for fabricating large number of nanowire biosensors at low cost, which can be used for early-stage cancer detection. I was also involved in collaboration with Mercedes Benz Fuel Cell Division in Vancouver. I proposed a sensor for pressure inside fuel cell stacks and the design was investigated.
