Contributions to research

1. I was the PI and lead Researcher on the project entitled: Designing a Heterogeneous Indoor Location Services Framework. Our goal was to improve upon the existing methods of high-resolution location awareness. We achieved this goal through two levels of investigation. First, we focused on the strategies to develop a framework for improving the reliability and resolution of heterogeneous micro location services. Second, we investigated and proposed strategies, through proof-of-concept prototypes, for the development of indoor context-aware mobile applications in order to improve the life experience of modern users in public and private indoor environments. In particular, an Indoor Location Service (ILS) framework was constructed based on a set of technologies and methodologies (e.g., Wi-Fi technology based on Received Signal Strength Indicator [RSSI]).

2. I was the Principal Investigator (PI) and lead Researcher on the project entitled: Novel, Low-Cost Covid-19 Point of Care Diagnosis Devices. The overall goal of this proposal was to rapidly manufacture low-cost (~$150) Point of Care (PoC) system to reach thousands of Canadians that are really in need of assessment and monitoring, to reduce the impact of COVID-19 and to save future Canadians’ lives. We developed a low-cost, ready-to-use and reliable COVID-19 PoC self-assessment and monitoring device by capitalizing on the existing Tech4Life mHealth solutions, underpinned by the current successful collaboration with Sheridan College and the capability of swift mobilization of resources. At the end of this project, the prototype was fully functional, and it was considered an actual product. The product focused on measuring the temperature of the forehead via IR and the oxygen level in the blood. The product can be further developed in the future to include more sensors to capture more use cases. The company will market the product and apply for approvals from Health Canada.

3. I was the PI on the project entitled: NewPneu: A cost-effective solution for detecting childhood pneumonia in low-resource communities. We designed and implemented a new low cost and real time mHealth system called NewPneu. The new hub design is the critical part among the system components. As part of the validation process, the new design demonstrated that it was highly accurate based on the strong linear relationship between the measured and applied frequencies. From our real life experiments conducted on participants, NewPneu further demonstrated that it was significantly accurate based on the following findings: 1) the confidence intervals between NewPneu and a gold standard device (i.e., CMS7000PLUS) were similar in terms of the collected biometric ˘data (i.e., SpO2 and Respiration Rate (RR)), 2) there were no significant differences between the two methods of measurements in terms of the means of the same biometric data, 3) there were significant correlations between NewPneu and the gold standard device in terms of the different biometric data, and 4) the two methods of measurements were within the limits of agreements. Moreover, the lifetime of our newly designed hub lasted for a significant amount of time compared to that for a commercial hub. Therefore, NewPneu is considered energy efficient system. Lastly, the new system is cost effective solution (~$10). Based on all these properties, NewPneu is considered reliable for the community-based health workers to monitor key signs of pneumonia in children in low resource settings
