Juris Doctor

Thanks to discussion with PK yesterday and further searching the information. Here is definition of Juris Doctor:

- Juris Doctor is a first professional graduate degree and professional doctorate.

From Bernama:
Oh holds a degree each in aeronautical and mechanical engineering, and another in German language, apart from a double masters -- in science and international management -- as well as Juris Doctor in Law (JD), obtained from his eight years of study at the University of California.

From Malaysiakini (cn):
来自沙巴亚庇的胡逸山现年35岁，有神童学者的美誉。他在16岁进入加利福尼亚大学就读8年，于19岁考获3个学士学位（机械工程、航天工程及德国文学），之后在两年内又取得两个硕士学位（工学和国际工商管理），并在24岁获得法学博士学位。

Bear in mind, this is just a first degree not the PhD equivalent.
