David is the author or co-author of more than 165 research papers, including results of lunar sample studies and experiments. David’s research focused extensively on magnetic studies and electromagnetic sounding, both terrestrially for exploration and mapping and in lunar mapping and exploration. Since 1971 he has served on a great number of scientific and academic committees on behalf of governmental or private sector organizations. In 1997, he was appointed by the Prime Minister to join with William Ruckelshaus, an appointee of the President of the U.S., to study the bitter Pacific Salmon controversy between the two countries. Their work and recommendations formed the basis for negotiation of a new agreement.
