The academic lineage or academic ancestry of someone is a chain of professors who have served as academic mentors or thesis advisors of each other, ending with the person in question. Many genealogical terms are often recast in terms of academic lineages, so one may speak of academic descendants, children, siblings, etc.
Websites such as the Mathematics Genealogy Project or the Chemical Genealogy document academic lineages for specific subject areas, while some other sites, such as Neurotree and Academic Family Tree aim to provide a complete academic genealogy across all fields of academia. However, not all links recorded in such databases are formal advisor-advisee relationships; for instance, the University of Cambridge did not require a formal doctoral thesis until 1919, and academic genealogies that include earlier Cambridge students tend to substitute an equivalent mentor.
Academic genealogies are particularly easy to research in the case of Spain's Doctor degrees, because until 1954 only Complutense University had the power to grant Doctorates. This means that all holders of a Doctor degree in Spain can trace back their academic lineage to a Doctoral supervisor who was a member of Complutense's Faculty.
Academic genealogy may influence research results in areas of active research. Hirshman et al. examined a controversial medical question, the value of maximal surgery for high grade glioma, and demonstrated that a physician's medical academic genealogy can affect his or her findings and approaches to treatment.
