The Department of Data Science at CityUHK is one of the first in the world dedicated to leading the development of this new discipline. The Department comprises an interdisciplinary faculty team of leading academics in multiple areas including data science foundations (machine learning, statistics, optimization, and AI for Science) as well as data science powered applications (smart cities, Industry 4.0, FinTech, energy, public health, and precision medicine). Our PhD programme aims to offer students solid fundamentals of data science, which cover machine learning, statistics, computing, data analytics, and optimization, and nurture them to produce state-of-the-art research in data science. Selected research areas include:

• Machine Learning Theory and Algorithms (including deep learning, statistical learning, optimization, and reinforcement learning, etc.)
• Artificial Intelligence for Science
• Smart Cities and Industrial AI (Internet of Things, smart manufacturing, intelligent transportation, power and energy systems, smart healthcare and precision medicine, etc.)
• Business Data Analytics and Financial technology (FinTech)
• Data Science for Social Media, Innovation, and Policy
