Electrical Engineering & Computer Science
Razieh (Neda) Salahandish has obtained her Ph.D. in electrochemistry in 2018, with her doctoral research focus on the synthesis and fabrication of nano-structure-based biosensors for early-stage ultra-sensitive detection of Breast Cancer. Prior to joining the Lassonde School of Engineering, she has been a post-doctoral fellow (2019-2022) at the University of Calgary, Department of Biomedical Engineering, developing in-vitro diagnostic (IVD) platforms for clinical early diagnosis of various disease biomarkers, including quantitative rapid detection of COVID-19. Currently an Assistant Professor at the Department of Electrical Engineering and Computer Science at York University, she leads interdisciplinary research revolving around the development of miniaturized electrical and electrochemical sensors, integrated microfluidics systems, smart organ-on-chip platforms, and wearable medical devices. As an entrepreneurially minded scholar, she co-founded Criticare Dx in 2018, a start-up company in the field of medical device development. She has also been an academic collaborator with a variety of early-stage ventures in the advanced sensing field, such as CardiAI Inc and Selective Lab, enthusiastically pursuing her translational research.
