Mobility is crucial for human life as it affects various aspects of our biology, society, economy, and culture. Human movement has historically influenced societies through population and environmental changes, and it continues to be a natural occurrence despite modern limitations. Similarly, maritime transportation has been fundamental to global trade since the Age of Exploration. It remains one of the most important methods of coordinating and moving goods, accounting for over 80% of the world’s trade volume today. The ability to move efficiently across vast distances by sea has not only shaped economic landscapes but also fostered cultural exchange and technological advancements, underscoring the enduring significance of mobility in all its forms.
Mobility data refers to sequences of positional data that change over time, showing the movement of people, objects, or animals from one place to another. This data includes different modes of transportation like cars, trains, buses, or planes and various types of vehicles within the same mode, such as fishing vessels, cargo ships, tankers, and leisure boats. Research in this field focuses on modeling movement between different origins and destinations through techniques like link prediction or label propagation and reconstructing detailed mobility paths or trajectories using time-series forecasting or clustering.
Studying mobility patterns and predicting movements can help us understand how trajectories are influenced by environmental factors and vice versa. For example, vessel mobility is affected by atmospheric and ocean dynamics, which directly impact the marine environment. Similarly, urban mobility patterns are interconnected with infrastructure developments and traffic regulations. Additionally, road conditions and congestion significantly impact vehicle movements, affecting fuel consumption and CO2 emissions. Pedestrian mobility is directly influenced by sidewalk layouts, which play a vital role in safety and walkability. Furthermore, air traffic mobility is connected to airport logistics, airspace management, and weather conditions, impacting overall transportation efficiency and resulting in flight delays.
The doctoral student specializing in this topic will contribute to the development of techniques (i.e., algorithms for data preparation, techniques for data modeling, and complete pipelines for knowledge extraction) for mobility data mining and modeling focusing on the ocean environment and using sensors, such as Automatic Identification System (AIS) and hindcast data describing atmospheric and ocean conditions to improve our capacity of modeling anthropogenic effects while applying that knowledge to increase awareness and enhance decision-making for ocean management.
The Faculty of Computer Science is looking for a doctoral (PhD) or a master’s (MCS) student specializing in Mobility Data Mining within the Artificial Intelligence and Machine Learning cluster. The successful candidate will join a dynamic and dedicated research cluster and the group supervised by Prof. Gabriel Spadon, who has expertise in data analytics, graph mining, geoinformatics, and machine learning for spatial, temporal, and spatiotemporal data.
The PhD student will receive total funding and be enrolled in the Computer Science program at Dalhousie University in Halifax, Nova Scotia, Canada. The recruitment, admission, and study processes will follow the policies of Dalhousie University’s Faculty of Graduate Studies and Faculty of Computer Science. Additionally, the successful candidate may have opportunities to conduct research visits to national and international collaborators of Prof. Gabriel Spadon, as well as participate in international conferences and workshops as the candidate progresses toward the degree of PhD/MCS in Computer Science.
You are encouraged to apply even if you do not meet all the requirements of the ideal candidate.
The ideal candidate will be someone who:
Applicants should submit a detailed curriculum vitae, a transcript of records, and the contact information of two referees by email to Prof. Gabriel Spadon (spadon@dal.ca) with “Lastname Firstname CS PhD/MCS application #2025-01” as the subject line (i.e., put your last and first name in the email heading). Applications will be considered from July 1, 2024, until the position is filled. Note that only selected candidates will be contacted for an interview.
