Fellow

A fellow is a member of an academy, learned society or group of learned people (a fellowship) which works together in pursuing mutual knowledge or practice. There are many different kinds of fellowships which are awarded for different reasons in academia and industry. These often indicate a different level of scholarship.

Education and academia
In education and academia there are several kinds of fellowships, awarded for different reasons.

Teaching fellowships
The title of (senior) teaching fellow is used to denote an academic teaching position at a university or similar institution and is roughly equivalent to the title of (senior) lecturer. The title (senior) fellow can also be bestowed to an academic member of staff upon retirement who continues to be affiliated to a university in the United Kingdom.

The term teaching fellow or teaching assistant is used, in the United States and United Kingdom, in secondary school, high school and middle school setting for students or adults that assist a teacher with one or more classes.

Medical fellowships
In US medical institutions, a fellow refers to someone who has completed residency training (e.g. in internal medicine, pediatrics, general surgery, etc.) and is currently in a 1 to 3 year subspecialty training program (e.g. cardiology, pediatric nephrology, transplant surgery, etc.).

As an academic position
The title of research fellow may be used to denote an academic position at a university or a similar institution; it is roughly equivalent to the title of lecturer in the teaching career pathway.

As a financial grant
Research fellow may also refer to the recipient of academic financial grant or scholarship. For example, in Germany, institutions such as the Alexander von Humboldt Foundation offer research fellowship for postdoctoral research and refer to the holder as research fellows, while the award holder may formally hold a specific academic title at their home institution (e.g., Privatdozent).

These are often shortened to the name of the programme or organization, e.g. Dorothy Hodgkin Fellow rather than Dorothy Hodgkin Research Fellow, except where this might cause confusion with another fellowship, (e.g. Royal Society University Research Fellowship.  )

In the context of graduate school in the United States and Canada, a fellow is a recipient of a postgraduate fellowship. Examples include the NSF Graduate Research Fellowship, the National Defense Science and Engineering Graduate Fellowship, the Guggenheim Fellowship, the Rosenthal Fellowship, Woodrow Wilson Teaching Fellowship and the Presidential Management Fellowship. It is granted to prospective or current students, on the basis of their academic or research achievements.

In the UK, research fellowships are awarded to support postdoctoral researchers such as those funded by the Wellcome Trust and the Biotechnology and Biological Sciences Research Council (BBSRC). At ETH Zurich, postdoctoral fellowships support incoming researchers. The MacArthur Fellows Program (aka "genius grant") as prestigious research fellowship awarded in the United States.

Fellowships as a training program
Fellowships may involve a short placement for capacity building, e.g., to get more experience in government, such as the American Association for the Advancement of Science's fellowships and the American Academy of Arts and Sciences.

Fellowships as a special membership grade
Fellows are often the highest grade of membership of many professional associations or learned societies, for example, the Chartered Institute of Arbitrators or Royal College of Surgeons. Lower grades are referred to as members (who typically share voting rights with the fellows), or associates (who may or may not, depending on whether "associate" status is a form of full membership). Additional grades of membership exist in, for example, the IEEE and the ACM.

Fellowships of this type can be awarded as a title of honor in their own right, e.g. the Fellowship of the Royal Society (FRS). Exclusive learned societies such as the Royal Society have Fellow as the only grade of membership.

Appointment as an honorary fellow in a learned or professional society can be either to honour exceptional achievement and/or service within the professional domain of the awarding body or to honour contributions related to the domain from someone who is professionally outside it. Membership of the awarding body may or may not be a requirement.

How a fellowship is awarded varies for each society, but may typically involve some or all of these:
 * A qualifying period in a lower grade
 * Passing a series of examinations
 * Nomination by two existing fellows who know the applicant professionally
 * Evidence of continued formal training post-qualification
 * Evidence of substantial achievement in the subject area
 * Submission of a thesis or portfolio of works which will be examined
 * Election by a vote of the fellowship

In ancient universities
At the ancient universities of the University of Oxford, the University of Cambridge, and Trinity College, Dublin, members of the teaching staff typically have two affiliations: one as a reader, lecturer, or other academic rank within a department of the university, as at other universities, and a second affiliation as a fellow of one of the colleges of the university. The fellows, sometimes referred to as University dons, form the governing body of the college. They may elect a council to handle day-to-day management. All fellows are entitled to certain privileges within their colleges, which may include dining at High Table (free of charge) and possibly the right to a room in college (free of charge).

At Cambridge, retired academics may remain fellows. At Oxford, however, a Governing Body fellow would normally be elected a fellow emeritus and would leave the Governing Body upon his or her retirement. Distinguished old members of the college, or its benefactors and friends, might also be elected 'Honorary Fellow', normally for life; but beyond limited dining rights this is merely an honour. Most Oxford colleges have 'Fellows by Special Election' or 'Supernumerary Fellows', who may be members of the teaching staff, but not necessarily members of the Governing Body.

Some senior administrators of a college such as bursars are made fellows, and thereby become members of the governing body, because of their importance to the running of a college.

In the U.S.
At Harvard University and some other universities in the United States, "fellows" are members of the Board of Trustees who hold administrative positions as non-executive trustee rather than academics.

Industry and corporate fellows
In industries intensive in research and development (R&D), companies may appoint a very small number of top senior researchers as corporate or technical Fellows, either in Science or in Engineering. These are internationally recognized R&D leaders who are among the best in the world in their respective fields.

Fellow is the most senior rank or title one can achieve in a scientific or engineering career, though fellows often also hold business titles such as Vice President or Chief Technology Officer.

Notable examples of science and engineering fellows in R&D-intensive organizations include IBM Fellows, Microsoft Fellows, Boeing Fellows and ICL Fellows.

Nonprofit and government fellowships
The title fellow can be used for participants in a professional development program run by a nonprofit or governmental organization. This type of fellowship is a short term work opportunity (1–2 years) for professionals who already possess some level of academic or professional expertise that will serve the nonprofit mission. Fellows are given a stipend as well as professional experience and leadership training.
