Paul Alan Yule

[4] In the 1980s, with the support of Swami Omanand Saraswati, he catalogued and evaluated metallic artefacts of the so-called Copper Hoard Culture by means of European methods and models for the first time, whereby numerous finds came to light especially in the Kanya Gurukul in Narela/Haryana.

He documented the early historic fortress at Sisupalgarh by means of a laser scanner, ground penetrating radar and a hand-held GPS receiver.

In the mid 1990s Yule and Weisgerber mapped and studied the tower tombs of Jaylah in the eastern part of the Jebel Akhdhar, which may date to the Bronze Age Umm an-Nar Period mid-late 3rd millennium BCE.

The one known from the most sites is designated Samad Late Iron Age, the other is the "période préislamique récente"[14] which mostly French and Belgian colleagues researched and defined in the United Arab Emirates.

[15] Years after finishing the actual report, Yule realised the important publications for the excavations at al-Akhdhar, al-Wāsiṭ tomb W1 and other projects.

[16] In 2012 the Ministry of Heritage and Culture asked him to document and published an Early Iron Age metal smelting site just inside the Empty Quarter in Wadi Ḍank, ʿUqdat al-Bakrah.

[17] At the site of Zafar, capital of the Himyarite Tribal Confederation, in the Yemenite highlands, field operations continued from 1998 to 2010 with a budget which eventually amounted to 5,300,000 Euros.

[18] Yule considered late pre-Islam in the Yemen to be his most important scientific contribution owing to the opportunity to work for several years and the large number of contexted finds.
