I am most grateful to have received the Fuchs Memorial Award during the 2010 International Aerosol Conference in Helsinki, Finland. The award is sponsored jointly by the American Association for Aerosol Research (AAAR), the Gesellschaft fuel Aerosolforschung (GAeF), and the Japan Association of Aerosol Science and Technology (JAAST). An Award Committee of the International Aerosol Research Assembly (IARA,, consisting of 18 international member associations, selects the winner(s) every four years. The co-winner of this 2010 Fuchs Memorial Award was Prof. Markku Kulmala of the University of Helsinki. IARA website stated, “The Fuchs Memorial Award recognizes outstanding original research contributions to the field of aerosol science and technology. It is considered the highest honor for researchers in the field. Presented every four years at the International Aerosol Conference, the award memorializes the late Professor Nikolai Albertovich Fuchs, the great Russian scientist who is regarded by many as the “father of aerosol science””.

My professional development has been filled with love and support of my family. My wife Therese took care of the children while working full-time, so that I could spend long hours at work particularly during the early years. Our three children are now high achievers in medical and engineering fields, each of them and their spouses blessed us with two grandchildren. Attached is a family photo taken in September 2022, with children and their spouses (Christine and Eric, Jonathan and Hyonju, Elizabeth and Kyle) and grandchildren (Jonah, Joshua, Ryker, Nathan, Elena and Averly). We are very fortunate that they all live within 15 minutes away from our house, and have 14 birthdays to celebrate every year! I also appreciate the encouragement and support from my brother Dr. Ching-Hon Pui, former Chair of Oncology at St. Jude Children’s Research Hospital.

One of the major programs during this period was funded by Intel on Extreme UV Lithography (EUVL) Mask Study. The objectives were to develop methods to evaluate and control particulate contaminant generation, transport and deposition in a mask handling system (Fig. 7). Prof. Fissan was a key investigator, and his student Dr. Christof Asbach, a CFR post-doctoral research associate, was a key contributor and is now the President of GAeF (Gesellschaft fuer Aerosolforschung)— the oldest aerosol association in Europe and the world. Other students/post-docs working on the Fig. 7. Prof. Emeritus Heinz Fissan of University of Duisburg-Essen was a key investigator of the EUVL contamination control study. His Ph.D. student Christof Asbach, subsequently a post-doc in Pui’s lab, was an important contributor and is now President of GAeF.
