His early works were published under the pseudonym of Andrew Warden (anagrams of his surname).
He has written a book on the card game bridge and has a website on the subject of double dummy problems.
He has a keen dislike for SQL due it's many violations of relational database theory and much prefers Tutorial D, a relational database language he helped create. In many of his lectures he places emphasis on this dislike and never fails to point out problems with SQL that are not present in Tutorial D.
He is well known for his love of the XR-97 Database Architecture, as developed by Professor David VandeLinde
