Introducing Our Authors
MARYAM PARVIZ
Education. B.S. in Electronics Engineering and Physics, Istanbul Technical University, Istanbul, Turkey (2013); Exchange Student, Kungliga Tekniska Högskolan (KTH), Stockholm, Sweden (2010−2010); and Visiting Graduate Researcher, Cavendish Laboratory, University of Cambridge, Cambridge, UK (2013−2014). Nonscientific Interests. Traveling, philosophy, financial markets, and cooking. My current research focuses on the development of optical sensing platforms for nanoparticle detection with an emphasis on biosensing applications. Specifically, we are working on a specific type of wide-field interferometric microscope to detect and size biological nanoparticles in a label-free and high throughput format. Previously I worked on the development of hand-held MEMS FTIR spectrometers, and dynamic magnetization reversal mechanisms in thin films. Our article in this issue describes the use of a modified flatbed scanner that can be used as a standalone label-free low cost biosensormore importantly, as a tool easily integrated into existing fluorescence-based detection assays. With this study, we addressed the issue of repeatability by providing quality control, and possible calibration of arrays of molecular probes.

Current Position. Postdoctoral Research Associate, Initiative for Biomedical Materials & Devices (IBMD) and ARC Research Hub for Integrated Device for End-user Analysis at Low-levels (IDEAL), University of Technology Sydney, Australia. Education. B.C. in Biomedical Engineering, Amirkabir University of Technology, Iran (2008); M.S. in Biomedical Engineering (Biometerials), Amirkabir University of Technology, Iran (2010); and Ph.D. in Chemistry under the supervision of Scientia Professors Justin Gooding and Katharina Gaus, UNSW Sydney, Australia (2017). Nonscientific Interests. I enjoy being a mum, camping, swimming, and learning about commercialization of research from universities. I am working in a group focused on bioimaging and sensing using nanomaterials. My research focus is on developing biosensors for rapid detection of biomarkers in healthcare. In particular, I am interested in electrochemical and optical cellbased biosensors for screening the effect of surface chemistry, nanoparticles, and drugs on live species. Recently, I completed a three-month course on commercialization of biomedical devices, held by NSW Ministry of Health, Australia. In addition to fundamental scientific research, in my current position, I also undertake commercial activities with industrial partners, to fabricate robust, highly sensitive, and portable diagnostic tools for cancers and animal health.
