Profile
    Dr. Chuen-Jinn Tsai is Chair Professor of the Institute of Environmental Engineering, Naitonal Chiao Tung University, Taiwan. He was trained as a mechanical engineer at the Mechanical Engineering Department, National Taiwan University, and received his MS and Ph. D. in the Particle Technology Laboratory (PTL), Mechanical Engineering Department, University of Minnesota. During his study in PTL, he worked with thesis advisors Dr. David Pui and Benjamin Liu on various research topics including aerosol sampling and transport, denuder, particle adhesion, bounce and re-entrainment, micro-contamination control, and instrument calibration.
    In 1990, Dr. Chuen-Jinn joined the Institute of Environmental Engineering, National Chiao Tung University, Taiwan, where he established one of the best aerosol laboratories, Nanoparticle and Air Quality Laboratory, in Taiwan to conduct researches on aerosol sampling instruments, aerosol physics, aerosol control devices and air quality. He has the ability to fund his work as is evident from the number of grants and the amount of funding that he has received. Results that he has achieved are fruitful with 107 referred journal papers and 10 patents. The samplers that he has designed and calibrated include impactors, cyclones, porous metal denuders, wet denuders, coil-type denuders, many of which have been used in air quality study of acidic aerosols, respirable particle sampling in the work places, improvement of the removal efficiency of wet scrubbers and aerosol size distribution measurements. Theoretical study of the collection efficiency of inertial impactors leads to a reversed trend of St50-Re relationship with that of Radar and Marple (1985). Using the porous media as the impactor substrate and based on the theory that he developed, he is able to eliminate solid particle bounce from the surface and increase the solid particle loading on the substrate. He has applied aerosol science and technology successfully in the design and use of air pollution control devices including high-efficiency of venturi scrubber (condensation and evaporation of fine particles), wet scrubber (mass transfer of fine water mist), and nanoparticle axial flow cyclone (enhanced slipped correction factor in vacuum), high-efficiency nanoparticle charger and wet ESP. The nanoparticle cyclone has been used in nanopowder classification to increase the value of nanopowders, and high-efficiency venturi scrubber and wet scrubber have been implemented in the industry to eliminate fine particle and acid emissions.
    In the past 17 years, Dr. Chuen-Jinn has educated and graduated 75 master and 6 Ph. D. students, who later on become important engineers, researchers and educators applying aerosol science and technology in their own fields. Through many symposia and workshops that he has organized, aerosol technology has also been assimilated and applied in many fields of disciplines. With the help of 8 well known professors and experts from abroad, he was the first to organize the 1st aerosol short course in 1992 attracting 150 attendees in Taiwan.
    Dr. Chuen-Jinn was one of the key founding members of CAART (Chinese Association for Aerosol Research in Taiwan), and AARA (Asian Aerosol Research Assembly). His involvement of CAART as the founding general secretary and later on as the vice president and president has turned CAART into an important academic society in Taiwan and a key aerosol society in Asia. There are now about 300 active domestic and foreign members. Besides annual aerosol conference of about 250 attendees, CAART has been publishing an International journal, AAQR (Aerosol and Air Quality Research, http://www.aaqr.org/), for which he is now the co-Editor-in-Chief (with Professors Judy Chow and Yoshio Otani). Together with 30 internationally renowned editorial board members, AAQR will continue to grow as a key aerosol and air quality journal in Asia and around the world. Representing CAART, Dr. Chuen-Jinn has played an important role in the founding and continuing development of AARA since 2001, which is now holding the bi-annual Asian aerosol conference (AAC) and conferring the Asian Young Aerosol Scientist award during the conference. He served as the chair of the award committee to confer the first Asian Young Aerosol Scientist award in 4-th AAC, Mumbai India, 2005.
    Dr. Chuen-Jinn chaired the 6-th International Aerosol Conference in Taipei, Taiwan, in September 2002, which was well attended by more than 600 people and was praised to be a very successful conference. He was the technical chair of the 5-th Asian aerosol conference, and the co-chair of the 3rd International Symposium on Nanotechnology and Occupational and Environmental Health held in Taiwan, from Aug. 26 to Sep. 1, 2007. He will continue to serve in the aerosol community as the president of AARA, the web committee member of IARA. In 2006, he received the International Aerosol Fellow award from the International Aerosol Research Assembly in honor of his outstanding contribution to research, technical development, education and service in aerosol science and technology.
