Prof. Sreeraman Rajan, an Associate Professor in the Department of Systems and Computer Engineering and Canada Research Chair in Advanced Sensor Systems and Signal Processing has had his Tier 2 Chair renewed. The announcement was made December 16th, 2020 by The Honourable Navdeep Bains, Minister of Innovation, Science and Industry. Rajan’s ongoing research will continue to position Canadian companies as global leaders in emerging sensor systems and enhance the health, safety, and security of Canadians by enhancing the quality and integrity of sensor data through novel data processing approaches.

Living in a world of sensors

Sensors are everywhere – even in places where we never would have imagined them. We can find them in our clothes, cars, homes, and offices. Sensors manage our lives. They allow entry into our houses and vehicles and tell us when to eat, walk, exercise, and sleep. We consult sensors for almost every aspect of our daily routines. Our world has become a complex web of sensors.

Sensors connect us to everything, control everything, and alter our perceptions. We now see the world through the “eyes” of sensors. Because sensors have such a significant impact on our lives, it is imperative that they are subject to appropriate checks and bounds. The intelligent manipulation of sensor data enables us to impose limits on what sensors can and cannot do in order to protect our privacy and security.

Prof. Rajan aims to safeguard our sensed data from exploitation by cleaning the sensor data to make meaningful inference; extracting the information to reveal what the sensor has reported; and using the information produced by many related sensors to further strengthen the inference and execute a meaningful action. Prof. Rajan’s advanced signal processing algorithms will ensure that current and emerging advanced sensors are safe from intrusion and that they produce meaningful data without sacrificing integrity.

In a world of connected sensors, Prof. Rajan’s research will lead to the improved quality, integrity, and privacy of the sensed data while enhancing the health, safety, and security of Canadians in our increasingly digital world.
