Postdoctoral researcher
Person professionally conducting research after the completion of doctoral studies From Wikipedia, the free encyclopedia
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). Postdocs most commonly, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. According to data from the US National Science Foundation, the number of holders of PhD in biological sciences who end up in tenure track has consistently dropped from over 50% in 1973 to less than 20% in 2006.[2] 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.[3][4]

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. Postdoctoral researchers typically work under the supervision of a principal investigator. In many English-speaking countries, postdoctoral researchers are colloquially referred to as "postdocs".[5]
Due to the nature of their work in some fields,[6][7][8][9][10][11] and an oversupply of graduating PhD students in many fields,[12][13] some postdoctoral researchers in certain countries face an uncertain future in academia,[4][14] and a large proportion will not gain tenure[15] or a coveted faculty position in their chosen field of research.[16][17][18][19]
A study on the topic was conducted in collaboration between Virginia Tech and MIT in 2018.[20] The authors found that only about 17% of postdocs ultimately land tenure-track positions. In the 1970s the number for PhD holders in biological sciences was 50%, illustrating how that generation had a significantly different job market.[2]
As of 2022, however, and the broad shifts in the labor market in response to the COVID-19 pandemic, postdoc positions in at least some fields are going unfilled due to a lack of applicants.[21]
In the United Kingdom in 2003, 25% of PhD graduates in the natural sciences continued to undertake post-doctoral research.[22] 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.[23]
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.[3] Postdoctoral researchers play an important role in spearheading postgraduate research activity in the US. The median salary of postdoctoral researchers 1 to 5 years after receiving their doctoral degrees is $42,000, 44% less than the $75,000 average for tenured positions.[24] The National Postdoctoral Association (NPA)[25] and Boston Postdoctoral Association (BPDA)[26] are nonprofit organizations that advocate 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 position within 5 years after they received a doctoral degree was about 39%;[24] nearly 10% of postdoctoral researchers were over 40 years old in 2003.[27]
On the other hand, 85 percent of engineering doctoral degree holders are likely to initially go into business or the industry sector.[28] 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[29] 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.[30] 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.[31] There exists fear that foreign PhD's are taking postdoctoral research positions from American researchers. 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 to 4%.[31]
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.[32] 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%.[33]
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.[34] In California, new postdoctoral appointments receive at least the NIH postdoctoral minimum salary ($50,004 in 2019) and many receive annual pay raises of 5% to 7% or more in accordance with the NIH's Ruth L. Kirschstein National Research Service Awards (NRSA).[35][36]
In 2014, postdoctoral researchers in Boston organized the "Future of Research" Symposium to respond to a conversation about the state of biomedical research[37] 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.[38] 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.[39]
Most of India's premier engineering, science and management institutes (like Indian Institute of Science (IISc), Indian Institutes of Technology (IITs), Indian Institutes of Science Education and Research (IISERs), Indian Institutes of Management (IIMs) and All India Institutes of Medical Sciences(AIIMS) have postdoctoral positions. The salary typically varies from ₹40,000 to ₹70,000 per month. For example, IIT Kharagpur, IIT Guwahati, IIT Delhi, IIT Kanpur, IIT Bombay, IIT Madras, IISER Bhopal, IISER Mohali, IISER Pune, IISER Kolkata, IIM Kolkata offer postdoctoral fellowships.[40] The Indian Council of Social Science Research also offers fellowship(s) for pursuing a post doctoral degree. [41]
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,[42] A$75,404 p.a. at the University of Melbourne,[43] and A$75,612 p.a. at the University of New South Wales.[44]
Alternatively the Australian Research Council (ARC) provides Postdoctoral Fellowships. For example, their Discovery Projects,[45] funds 3 year Fellowships, beginning in 2009, with A$61,399 p.a.[46] Furthermore, a mandatory superannuation payment of 11–17% is paid by Universities.[47]
The postdoctoral system in China was founded in 1985 upon suggestion by Chinese American physicist and Nobel laureate Tsung-Dao Lee.[48] The Office of the National Administrative Committee of Postdoctoral Researchers (Chinese: 全国博士后管理委员会办公室) regulates all postdoctoral mobile stations (Chinese: 博士后科研流动站) at universities and postdoctoral work stations (Chinese: 博士后科研工作站) at institutes and enterprises in mainland China. Applicants to postdoctoral positions have to pass a detailed medical check-up in order to enter the stations (Chinese: 进站). Postdoctoral researchers are required to undergo regular evaluations, and submit a research report for evaluation at the end of the postdoctoral period to obtain approval to leave the stations (Chinese: 出站). Those who are approved to leave the stations will receive a postdoctoral certificate from the national administration office.[49] In some universities, postdoctoral researchers who fail to leave their stations normally, either due to failing their evaluations or early withdrawal from the stations (Chinese: 退站), may be asked to pay back the grants or even the salaries that they have received.[50][51][52][53][54][55][56] Because of the way that the postdoctoral system is managed, postdoctoral research is widely mistaken to be an academic degree in China. The government's administration of the postdoctoral system has been criticized for hindering innovative research, as too much effort is spent on evaluations, and overemphasis on performance prevents the creation of a relaxing research environment.[57]
