My research integrates innovative methods from engineering, machine learning, and geographic information science to create context-aware solutions for healthcare. This cross-disciplinary effort, to this date, has resulted in innovative techniques to study people in the context of their everyday environments and new insights into the relationship between mobility behaviours and cognitive functions. Through this work, our goal is to explore whether a human-centric approach to machine learning can assist in the detection, diagnosis, monitoring, and treatment of health problems including dementia. Currently, our team's interests include automobile technology, driving behaviours and mobility in older adults and individuals with dementia.

Raya Hafezifar

  • Grey LinkedIn Icon

MSc Student, Geomatics Engineering

I joined the Healthy City Lab as a Geomatics Engineering MSc student in January 2022. I have experience in Geospatial Intelligent System (GIS), databases and data mining methods. Throughout my studies, I have been involved in various projects on Spatial Data Science, ranging from analyzing trajectory data for developing a web mapping application to mining frequent patterns for trip purpose prediction. In the summer of 2021, through the Mitacs Accelerate Explore program, I worked on creating smart forms for immigration applications by applying Artificial intelligence methods.

Kelly Long

MSc Student, Biomedical Engineering

After graduating from the University of Calgary’s Geomatics Engineering program in 2021 with a minor in Data Science, I joined a Land Surveying company as a Party Chief and Engineer in Training. I am passionate about the field of Geomatics for the technical applications as they relate to my hobbies and interests. These include outdoor activities such as rock climbing and skiing, as well as programming and exploring the uses of spatial data in a health context. Joining HCL as a Biomedical Engineering MSc student felt like a natural progression given my background and interests and I am grateful to be a part of the team.

Emily Dittmer

Summer Research Student

My name is Emily Dittmer, and I am currently entering my third year of studies at the University of Calgary from the Faculty of Kinesiology pursuing a BSc in Biomechanics with a minor in Computer Science. I am particularly interested in technological applications in health solutions and am fascinated by the possibilities as to what can be achieved using technology to help better human health. As a Calgary native, I love to go skiing, mountain biking, and hiking.


Maria Law

Summer Research Student

My name is Maria and I am a biomedical engineering (BSc) student at UofC. My hobbies range from cooking and biking to music and biomechanics.


I also have interests in multiple fields of engineering, including geomatics, so I am excited to be joining Dr. Bayat's team this summer to explore the link between driving patterns, human behaviour and health. 


Noel Thomas

Thesis Student

During my time pursuing my B.Sc. in Software Engineering (Minor in Biomedical Engineering), I became enthralled by the applications of artificial intelligence in today’s world. Over time, I got to know how machine learning methods were being used to reveal some of the well-kept secrets of nature. To me this new paradigm enables us to solve complex problems that are not possible through more traditional approaches.

Outside of school/work I like to read books (esp. philosophy), volunteer for causes I believe in, explore art galleries, try out new cooking recipes, and play sports with friends.
