|PhD or equivalent|
A postdoctoral researcher or postdoc is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other fields. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualifications or certification, while in other countries it does not.
Postdoctoral research may be funded through an appointment with a salary or an appointment with a stipend or sponsorship award. Appointments for such a research position may be called postdoctoral research fellow, postdoctoral research associate or postdoctoral research assistant. Depending on the type of appointment, postdoctoral researchers may work independently or under the supervision of a principal investigator. However, a designated postdoctoral research appointment may also be taken up when other suitable positions are not available, rather than merely pursuing the deepening of scholarly experience. In many English-speaking countries, postdoctoral researchers are colloquially referred to as "postdocs".
Due to the nature of their work, and an over-supply of graduating PhD students in many fields, some postdoctoral researchers face an uncertain future in academia, and a large proportion will not gain tenure or a coveted faculty position in their chosen field of research.
Since the landmark ruling in the employment tribunal (Scotland) Ball vs Aberdeen University 2008 case (S/101486/08), researchers who have held successive fixed-term contracts for four years' service are no longer temporary employees but are entitled to open-ended contracts.
In the US, a postdoctoral scholar is an individual holding a doctoral degree who is engaged in mentored research or scholarly training for the purpose of acquiring the professional skills needed to pursue a career path of his or her choosing. Postdoctoral researchers play an important role in spearheading research activity in the US. The median salary of postdoctoral researchers is $42,000 a year for up to 5 years after receiving their doctoral degrees-- 44% less than the $75,000 average for tenured positions. The National Postdoctoral Association (NPA) is a member-driven organization that provides a voice for postdoctoral scholars in the United States.
Postdoctoral research may be required for obtaining a tenure-track faculty position, especially at research-oriented institutions. Post-doctoral appointments that were traditionally optional have become mandatory in some fields as the degree of competition for tenure-track positions in academia has significantly increased over previous decades. In fact, the small supply of the professional positions in academia compared to the growing number of postdoctoral researchers makes it difficult to find tenure-track positions. In 2008, the proportion of postdoctoral researchers who got a tenure or tenure-track within 5 years after they received a doctoral degree was about 39%; nearly 10% of postdoctoral researchers were still waiting for tenure-track positions over 40 in 2003.
On the other hand, 85 percent of engineering doctoral degrees holder are likely to initially go into business or industry sector. Under the circumstances, providing doctoral students as well as postdoctoral researchers with necessary skills for nonacademic positions has become one of the important roles for graduate schools and institutions. The America COMPETES Act recognized the importance of graduate student support for obtaining skills needed when they pursue nonacademic careers, and required National Science Foundation (NSF) to increase or decrease funding for the Integrative Graduate Education and Research Traineeship (IGERT) programs at least at the same rate as it increases or decreases funding for the Graduate Research Fellowship. There are no comprehensive data of international postdoctoral researchers in the US because of the less-organized survey and the difficulty in counting international postdoctoral researchers. The proportion of postdoctoral researchers on temporary visas reached 53.6% in 2010. The life sciences hold the largest percentage of postdoctoral researchers on temporary visas; in 2008, approximately 56% of postdoctoral researchers in the life sciences were temporary residents. Of these postdoctoral researchers on temporary visas, four out of five earned their PhD outside of the United States. While there exists fear that foreign PhD's are taking postdoctoral research positions from American researchers, it is not true. However, the influx of foreign PhD's has influenced the supply of ready-researchers, and thereby, the wages. One estimate claims that a 10% increase in the supply of foreign postdoctoral researchers lower the position salary by 3-4%.
In the US, life sciences have a greater share than other fields due to higher federal funding of life and medical science areas since mid 1990 . One survey shows that 54% of postdoctoral researchers major in life sciences, whereas those who majored in physical science, mathematics, and engineering account for 28%.
In 2010, postdoctoral researchers in California formed a union, UAW Local 5810 in order to secure better working conditions such as the right to file a complaint for alleged discrimination or sexual harassment through a formal grievance procedure. In California, new postdoctoral appointments receive at least the NIH postdoctoral minimum salary ($39,264 in 2011) and many receive annual pay raises of 5-7% or more in accordance with the NIH's Ruth L. Kirschstein National Research Service Awards (NRSA).
In 2014, postdoctoral researchers in Boston organized the "Future of Research" Symposium to respond to a conversation about the state of biomedical research from the perspective of junior scientists. The meeting included panel discussions with academics concerned about the scientific enterprise, a video message from Massachusetts senator Elizabeth Warren, and workshops discussing training, funding, the structure of the biomedical workforce, and metrics and incentives in science which were used to generate recommendations in a white paper. Meetings organized by postdoctoral researchers in 2015 spread to New York University (NYU), Chicago and San Francisco and a second meeting in Boston discussed data collection, labor economics and evidence-based policy to advocate for changes to science, including the future of the PhD.
Most of India's premier engineering, science and management institutes (like Indian Institutes of Technology (IITs), Indian Institutes of Science Education and Research (IISERs) and Indian Institutes of Management (IIMs)) have postdoctoral positions. The salary typically varies from INR 40,000 - 70,000 per month, far less than the minimum wage in most countries. For example, IIT Kharagpur (http://www.iitkgp.ac.in/academics-post-doc-fellowships), IIT Delhi, IIT Kanpur (http://www.iitk.ac.in/new/postdoctoral-vacancies), IIT Bombay, IIT Madras, IISER Mohali, IISER Pune, IISER Kolkata, IIM Kolkata offer postdoctoral fellowships.
Salaried appointments at the minimum Level A, Step 6 for academic salaries, for doctoral qualified employees (beginning in 2008) are set at A$75,612 p.a. at the University of Sydney, A$75,404 p.a. at the University of Melbourne, and A$75,612 p.a. at the University of New South Wales.
Alternatively the Australian Research Council (ARC) provides Postdoctoral Fellowships. For example, their Discovery Projects, funds 3 year Fellowships, beginning in 2009, with A$61,399 p.a. Furthermore, a mandatory superannuation payment of 11-17% is paid by Universities.
