Dr Yam has devoted a decade of intensive research to the application of lexicography to grammar and built up databases of the kind used only by a limited number of dictionary publishers. Graduated from the University of London, he pioneered teaching English and math on British television (Prestel), and went on to provide solutions for physics and chemistry problems. Subsequent software products for the American market include the Picture Dictionary (forerunner of Raytheon's Wordless Picture Story Books) and the Rovabot series on elementary English.
Dr Yam also invented computer music in 1987 and utilized speech technology to make digital telephony available to the disabled when ADA law came into force in 1994.
Author of over 50 books and papers, Dr Yam wrote the English version of the construction code for Europe (Currently 28 Member States), edited by Professor Oslund of Sweden. He also developed English Grading Software for Oxford University Press in 2008.

I obtained this book for a friend who is studying English. So far, it seems to be a clearly written book that is considerably superior to the book assigned by her Professor, which is incredibly obtuse. Kudos to the author!

I like this book because there are interactive exercises that make learning really easy and effective. I've looked at several grammar ebooks, including those priced around $20. Their exercuses are simply printed out in exactly the same way as the paper version. Dr. Yam's exercises, however, provide responses to correct and incorrect answers, with plenty of relevant information. Even if you are on the move, you can learn something new every few seconds. Does anyone know why there're no interactive exercises on ebooks till now, or am I not looking hard enough?
