Ravi Prakash
Associate Professor
Biography
Dr. Ravi Prakash received his B.Sc. degree (2008) in Mechanical and Biomedical Engineering from Indian Institute of Technology Madras, India, and his M.Sc. (2010) and Ph.D. (2013) in Electrical and Computer Engineering from University of Calgary, Canada. Prior to joining Carleton in 2018, he worked as Assistant Professor in the Electrical Engineering Department at Queen’s University (2017-18), and as an NSERC postdoctoral fellow (2015-16) in Calgary. His research contributions are primarily in the fields of Lab-on-Chip micro-devices, biosensors for point-of-care diagnostics, soft-wearable systems for continuous, non-invasive health monitoring, environmental monitoring systems, cost-effective copolymer semiconductor, conductor and superconductor materials, and micro/nano fabrication techniques. His career accomplishments over the past eight years include over 40 peer-reviewed publications, including 21 journal publications, 15 conference publications, 2 book chapters, 3 patents, and over 20 invited talks/seminars.
At Carleton University, Dr. Prakash oversees the Organic Sensor and Devices Laboratory (OSDL), investigating organic, label-free chemical and biological sensors, screen-printed bio-electronic microsystems, flexible organic electronic components for wearables and human-device interfacing, and smart surfaces and interfaces for environmental monitoring applications. OSDL research initiatives regularly attract collaborators from industry and academic partner institutions in Ontario, across Canada and internationally, and sustains and supports a strong cluster of undergraduate, graduate and post-doctoral trainees.
Dr. Prakash is a licensed professional engineer in the province of Ontario, and member of several technical organizations including Institute of Electrical and Electronics Engineers (IEEE), the IEEE Engineering in Medicine and Biology Society, IEEE Sensors Council, and the Canadian Engineering Education Association (CEEA). He serves as peer reviewer for several international journals.
Research
The recent advancements in organic semiconductor, conductor and dielectric materials and micro/nanofabrication techniques have yielded exciting developments in the domain of low-cost, flexible electronic devices and systems. The choice of carbon-based semiconductor materials has opened several possibilities for designing electronic system topologies using organic transistor devices, screen-printed disposable sensors and integrated systems for wearable technology and point-of-care applications. Polymeric semiconductor and conductor materials are highly promising for developing disposable micro/nano technologies which can be produced through room temperature facile fabrication process and are suitable for low-cost flexible printed microelectronic systems.
