Computational Geometry

Almost all problems can be expressed in terms of geometry. Under the leadership of Dr. Yeganeh Bahoo, the Geometric Computing lab explores algorithm design and data structures specific to such problems. By combining geometry and computer science, the lab develops new insights and targeted solutions for a wide variety of current and potential industrial applications, such as:

  • Transmission of communications over wireless networks
  • Motion and visibility problems for robotics
  • Collision detection in virtual reality
  • Optimal route planning for search-and-rescue scenarios
  • … and more

Most recently, the lab has worked with industry partner, CAMufacturing Solutions Inc. to design automated toolpaths for 3D printers in additive manufacturing, based on the tessellation of triangles in a mesh to graphically represent a 3D surface.

Computational Public Safety & Robotics

The Computational Public Safety Lab (external link)  has been developing real-world applications for over 20 years. Professor Alex Ferworn and his multidisciplinary team have produced award-winning work featured in Vice Media, The Discovery Channel, the Toronto Star and many other venues. The Computational Public Safety Lab currently focuses on designing and developing applications to assist emergency responders in saving lives. Recent projects include:

  • Drones/Unmanned Aerial Systems (UAS) for search-and-rescue operations attempting to find lost people with dementia
  • Virtual 3D Disaster Scene Reconstruction Models for studying and predicting disaster rubble behaviour, and
  • Game-Based Tools and Simulations for first responders involved in making Improvised Explosive Devices (IED) safe

Research Collaborations: The Computational Public Safety Lab conducts research in partnership with numerous educational, corporate and industrial organizations, the OPP, Durham Region Police, firefighters, canine handlers and a broad range of social scientists and others. It also maintains a close working relationship with Toronto Metropolitan's Library Collaboratory.

Software Engineering

Professor Andriy Miranskyy directs research on the many possible risks associated with the software engineering process, with a special focus on complex systems that analyze big data. If not detected and mitigated, any such risks could result in poor business decision-making, overburdening of customer support services, unplanned and prolonged outages, overshot budgets and project schedules. Risks may include improper testing of big databases, system failure associated with non-scalable algorithms, late-stage requirements introduced into the development cycle, and spikes in consumer-discovered product defects. By exploring how to quantify and mitigate risk, our lab aims to make the computing world a safer place.

This vibrant area of exploration blends the inter-relation of software engineering, machine learning, and data science. To reach our aim, we leverage technologies, such as

  • Data mining
  • Deep learning
  • Simulation
  • Blockchain
  • Cloud computing
  • Quantum computing
  • High performance computing

Industrial Collaborations: we validate our research on real-world projects with the help of industrial partners, such as Environics Analytics, eSentire, and IBM.
