Research
The main research topics of the group are to develop clean air technologies: mechanical systems for the collection, control, removal, or detection (using sensors) of biological and non-biological airborne particles in indoor environments towards air quality improvement or clean air, and to predict and measure the behavior of the particles using artificial intelligence and computer software.
Open positions
Graduate students
We are recruiting highly motivated graduate students from a wide variety of research fields who are interested in studying fluid mechanics, heat transfer, aerosols, bioaerosols, biotechnology, or environmental engineering. Graduate students are provided with monthly salaries and all tuition. Interested applicants should send an email to Prof. Jaesung Jang (jjang@unist.ac.kr) with CV including an English proficiency test score, (a) transcript(s), and at least one reference.
