One of the most satisfactory aspects of editing for academics who excel in their fields is that we are often associated with research directly important to us. That’s most definitely the case for our work since 2012 with a leading environmental studies professor in Hong Kong. This internationally recognised expert focuses on the daunting challenge of understanding the meteorological and air pollution problems of rapidly developing areas such as the Pearl River Delta, right on our doorstep. With our editing help he has published in such journals as Building and Environment, Environmental Science and Technology and Geoscience Letters, among very many others. We think of it as a way of doing our bit for the rest of the world.
