My Graduate Study at UWaterloo and UofM

My current PhD research focuses on:

1. Contactless radar-base health monitoring, particularly heart-rate sensing using reconfigurable intelligent surfaces (RIS).

2. Dynamic metasurface and beam-steering technologies for adaptive wireless sensing and detection.

3. Integration of machine learning and AI with RF and radar systems for more robust and scalable signal interpretation.

4. Design and prototyping of reconfigurable electromagnetic structures, including RIS platforms based on tunable materials and switching technologies.

5. Advanced signal processing algorithms for intelligent sensing in challenging environments.

My doctoral work explores how reconfigurable electromagnetic platforms can improve the performance of next-generation sensing systems. In particular, I am developing radar sensing solutions that combine hardware innovation with data-driven intelligence. This includes the design, fabrication, and testing of reconfigurable intelligent surfaces for beam control, as well as the use of machine learning and signal processing to improve the reliability of contactless physiological monitoring. My broader goal is to contribute to practical sensing technologies that are accurate, adaptive, and suitable for real-world deployment. 

Alongside my academic research, my PhD experience has also benefited from strong industry exposure. My Apple internship has further strengthened my perspective on scalable RF and antenna-related technologies, especially in data-driven wireless system development for manufacturing and sensing applications. This combination of academic research and industrial collaboration has helped me approach my PhD work with both scientific depth and practical impact in mind.

My PhD at the University of Waterloo is helping me build toward a long-term goal of developing impactful wireless and sensing technologies that connect rigorous electromagnetic engineering with practical applications in healthcare, intelligent systems, and advanced industry. It is a rewarding journey that continues to shape my growth as a researcher, engineer, and innovator.

Talking of my professors and my courses at the University of Manitoba:

I had the honor to work under the supervision of Professor Dustin Isleifson who is a professional engineer, knowledgeable teacher, organized person, and most importantly a kind soul. He guided me in my journey and I learned lots of hands-on experiences from him. I highly recommend him for the advisory if you're thinking about graduate school. I took his Remote Sensing Graduate-level course and really enjoyed it. In this course, I acquired grasp knowledge about dielectric modeling of complex mediums such as sea ice and wet soil, Normalized Radar Cross Section (NRCS) of different natural habitats,  different remote sensing devices such as scatterometer, Lidar, Radar, and Ground Penetrating Radar (GPR). I also got familiar with satellite imagery. 

My main research at the University of Manitoba was about remote sensing technology. My master's thesis includes topics such as:

1. Dielectric measurement techniques (Comparing the measurement results of different types of oil and sea ice substances such as brine with a commercially available dielectric probe with a designed C-band cavity resonator)

2. Dielectric modeling of oil-contaminated sea ice and simulation of Normalized Radar Cross Section of clean and oil-contaminated sea ice with the Small Perturbation Method (SPM).

3. Design and develop C-band Short Back-fire Antennas for remote sensing applications. The desired antenna would be a dual polarised (Vertical and Horizontal) short backfire antenna with wide impedance bandwidth (> 500 MHz) and high realized gain (> 14dBi). 

Taking the "Near Field antenna measurement system" course was one of the best parts of attending graduate school. Professor Puyan Mojabi is one of the best teachers (he has been awarded the best teaching professor) that I ever had. He is passionate about teaching and his class was my best class experience at the University of Manitoba. During his course, he mentioned the most recent discoveries in the field of antenna measurement systems which opened a lot of new doors to me as a graduate student and helped me to strengthen my understanding of electromagnetics and antenna measurement systems. During this course, I had the chance to get familiar with planar, cylindrical, and spherical measurement systems and work with Planar and Cylindrical Near-Field systems. We also had the chance to work with the Far-Field measurement system of the University of Manitoba. 

Professor Greg Bridges' "microwave materials measurement techniques" was one of the most practical courses that I ever had. He had designed seven different lab experiments for the course which led to a deep understanding of microwave measurement systems such as Time Domain Reflectometry (TDR) system, Cavity resonator, Parallel plate measurement, and Waveguide measurement system. Besides, I had the chance to calibrate VNA, and set up all seven experiments myself. He is a professional well-experienced teacher and very passionate about his work. 

During the final exam session which was 8 hours :), he bought doughnuts for everybody. That was so nice of him.
