1. Architectural design: This is the core field of doctoral research in architecture, including residential design, commercial architectural design and public architectural design. Researchers may focus on specific types of architectural design or explore new design concepts and methods.
2. Architectural history and theory: This field mainly studies the historical development of architecture, architectural theory and the relationship between architecture and society and culture. Researchers may conduct in-depth research on architecture in a specific historical period or region, or discuss the development and changes of architectural theory.
3. Building technology: This field mainly studies the design and construction technology of buildings, including building materials, structural design and construction methods. Researchers may develop new architectural technologies or study how to apply existing technologies to architectural design.
4. Urban Planning and Design: This major mainly studies urban planning and design, including urban spatial layout, transportation system and public facilities. Researchers may study how to improve the sustainability of cities, or how to improve the quality of life of urban residents.
5. Environment and architecture: This field mainly studies the relationship between architecture and environment, including building energy conservation, environmental impact assessment and green building design. Researchers may study how to reduce the environmental impact through architectural design, or how to use natural resources to provide energy demand for buildings.
