PhD in Synthetic Biology

Synthetic Biology at Pohang University of Science and Technology (POSTECH) is offered as a combined master's and doctoral program focused on engineering biological systems for defined purposes. The field applies engineering design principles to molecular biology and genetics, working with tools such as gene editing, metabolic engineering, and synthetic gene circuits to build organisms or biological components with new or enhanced functions. Doctoral students typically complete coursework in molecular biology, genetics, and bioengineering methods before undertaking laboratory research that might involve designing genetic circuits, engineering microbial strains, or developing biosensors, culminating in an original dissertation. Because synthetic biology sits at the boundary of biology and engineering, students often draw on computational modeling alongside wet-lab experimentation. Career paths for graduates include research roles in biotechnology and pharmaceutical companies, positions in agricultural biotechnology and industrial biomanufacturing, and academic research pushing the boundaries of engineered biological systems. The field has grown quickly as gene-editing and DNA synthesis technologies have become more accessible, opening applications in medicine, materials, and sustainable chemical production. Located in Nam-gu, South Korea, the coursework component of this program spans four years, with intakes in the middle of February or the beginning of September. All instruction is delivered in English, allowing international students to complete the degree without a Korean-language requirement. The combined master's and doctorate structure takes students from graduate coursework directly into dissertation research, suiting applicants with a background in molecular biology, genetics, or bioengineering who want to specialize in the design and construction of biological systems.
