Over time, Ohio State researchers hold their ground or show growth (rise in position relative to others) between 2005-2010 (the years examined). Improvements in positioning relative to the rest of the world are most notable for Earth and Planetary Sciences, Environmental Science, and Physics & Astrophysics.
When viewed by discipline and compared across the world, nearly all of Ohio State’s science and engineering disciplines are cited well above the world average. Ohio State also shows strength in the general arts and the general sciences, with citations well above the world and national averages.
The Ohio State University research standing is also rising relative to
U.S. peer institutions
When comparing Ohio State University to other large research universities in the United States, similar patterns of strengths and significant gains over 20 years (1990-2010 are the years examined) are seen. Among 10 large state research universities, Ohio State ranked second for growth in output of publications (35.5% growth), led only by the University of Michigan (40.3% growth). (None of the U.S. universities grew at rates above the world average because of the rapid growth on the world scene of Chinese universities.)
During 2000s, Ohio State produced an average of more than 4800 papers per year, with the number rising each year over the decade. This amounts to a productivity rate of just under three papers per researcher year, which is higher than most of the peer institutions. The journals in which Ohio State published were cited 33% more frequently than the world average, a good showing overall, but lower than most peer institutions.
During the same time period, Ohio State’s papers were cited above the world and U.S. averages. Ohio State had a respectable 17% of its papers in the top 10% of all cited papers, although this percentage also falls at the lower end among peer institutions, which range from 16% (University of Florida) to a high of 23% (University of Washington).
An analysis offering more detail than that provided by Excellence Mapping shows research
intensity combined with citation strength. This in-depth analysis reveals these outstanding disciplines (in terms of peer recognition, growth, and specialization) at Ohio State:
n Nuclear and particle physics n Astronomy and astrophysics n General physics
n Social science methods
n Communications and media studies n Bioinformatics
n Microscopy
Scientific Specializations at Ohio State
The Battelle Center analysis reveals Ohio State specializations in specific disciplines during the 2000s. Specializations (also called the research intensity) in a given field or subfield is determined relative to the overall scientific output in the global database. For example, if an institution has 10% of its papers in biology, and the count for biology papers at the international level represents only 5% of all papers, this institution is considered to be specialized in biology and would have a specialization
score of 2. In other words, a specialization means that an institution has twice as many papers in a given field (e.g., biology) as expected when compared to the percentage share of all papers in this same field.
The specializations were calculated in the Applied Sciences, Arts & Humanities, Economic & Social Sciences, Health Sciences and Natural Science and Engineering—categories delineated by the National Science Foundation in a taxonomy of fields and subfields of science and engineering.
The details about specializations can be matched with impact measures to show which areas of specialization also have a high impact. Scientists and engineers strive to create work that has a high impact. Institutions are interested in where they specialize. Many fields require significant investments in equipment and faculty. Knowing where specializations and impact converge can help institutions plan for future investments.
The figure below shows Ohio State’s natural sciences and engineering disciplines (2005-2009) in relation to one another on a map that shows those disciplines that are cited above the world average. On the right are the disciplines where Ohio State is specialized.

Research Collaborations Beyond Ohio State
Like many research institutions, Ohio State is increasingly collaborative, nationally and
internationally. In the mid-2000s, Ohio State’s national collaboration rate was 47%, in line with peer institutions. By 2010, the national collaboration rate for Ohio State had risen to 52%. International collaboration shows similar growth from 25% in the early 2000s to 32% of publications by 2010. The majority of its highly cited articles are coauthored with researchers from other institutions, and often, from other countries.
During the 2000s, Ohio State researchers were most likely to publish with collaborators from Harvard; University of Wisconsin-Madison; University of California-LA; Johns Hopkins; MIT; and University of Pennsylvania. At the international level, Ohio State published most frequently with colleagues from China, Italy, the United Kingdom, Canada, Germany, France, Japan, and Korea.
Regionally, Nationwide Children’s was a frequent collaborator.
Increased collaboration is a trend in all areas of science and technology: a study of nearly 20 million research articles over five decades and an additional 2.1 million patent records over three decades identified that, for virtually all fields, research is increasingly done as collaborative projects or teams.
Many collaborative projects occur across disciplines in interdisciplinary or multidisciplinary activities. Similarly, collaboration increasingly takes place across sectors such as industry – academia teams. Collaborations typically produce more highly-cited research than individuals do, and, amazingly, this team advantage is increasing over time. On average, collaborations now produce exceptionally high-impact research, even in cases that once were the domain of solo researchers or lone inventors.
Recent Impact of Ohio State Research
Ohio State scientists have remained highly productive in these fields in the past few years as well. Medical researchers have published the greatest number articles over the decade reviewed and remained highly productive in the past two years. In a review of the past 18 months, the field of Biochemistry/Molecular Biology was the most productive for Ohio State. Since the beginning of 2013, in the fields of Biochemistry/Molecular Biology/Oncology, Ohio State researchers published more than 3000 articles, with an article by John C. Byrd as the lead author being among the most highly cited for all Ohio State researchers, receiving well over 200 citations. This number of citations is remarkable for an article that has only been in circulation for one year.
In Engineering, Michele Nielsen led a team publishing a highly cited article in the journal Energy and Environmental Science. Similarly, Ohio State researchers were both productive and impactful (receiving citations in excess of expectations) in Chemistry with more than 300 articles receiving citations, and a top-cited article claiming 177 citations, out of more than 1000 articles. In Physics, Ohio State researchers joined dozens of collaborators in the thrilling search for the Higgs Boson, which resulted in a highly cited article in Physical Review Letters. These highly cited articles are all notable for the large numbers of coauthors listed, showing that Ohio State researchers are actively collaborating with the best institutions in the world.
As it has done for more than a decade, the field of Astronomy and Astrophysics at Ohio State continued to show high impact in the past 18 months. Total articles published or co-published by Ohio State researchers in this field exceeded 500. Ohio State’s Daniel H. Weinberg and Klaus
Honscheid joined other astronomers from all around the world to publish highly cited articles on space observation that had already claimed more than 125 citations each after just a few months in print. Again, a remarkable achievement.
The Web of Science parses the medical sciences into 1) General Internal Medicine, 2) Critical Care Medicine, 3) Research Experimental Medicine, and 4) Dentistry/Oral Surgery Medicine. Ohio State researchers showed high productivity and very high citation strength in these four areas, with Research Experimental Medicine being the strongest performer having both exceedingly high productivity of 850 articles, and being among the list of the most highly cited articles, with an article coauthored by Richard M. Goldberg in Lancet claiming more than 200 citations. Anesthesiology also had a strong citation count for one of its 2013 articles with Joseph Dasta coauthoring an article garnering close to 200 citations. Health Care Sciences Services performed well in citation strength, with Annie-Laurie McRee co-publishing a highly cited paper.
Genetics/Heredity and Cell Biology are fields where Ohio State researchers have evidenced high productivity in the past 18 months, as well as above-expected citation impact. In these fields, the numbers of articles published neared 1000, and the highest cited article, with Charles Shapiro among the coauthors, garnering more than 65 citations by the end of 2014. Pharmacology/Pharmacy and Immunology also had strong showings among articles receiving citations, and in having a highly cited
article published over the past 18 months.
In terms of sheer citation strength, Materials Science outperformed all other fields at Ohio State with hundreds of articles. One article, focusing on nanotechnology, with coauthors from Chemistry, the Department of Materials Science and Engineering, Physics, and involving Jay A. Gupta, Josh Goldberger, Wolfgang Windl, and Ezekiel Johnston-Halperin as coauthors, claimed more than 200 citations.
Toxicology also had good productivity and creditable citation strength.
Psychology, Behavioral Sciences, Neurosciences/Neurology and Developmental Biology outperformed expectations in terms of numbers of articles. Among the three fields, Ohio State
researchers published well more than 1500 articles over the past 18 months with good citation strength. In all of these sciences, the highest cited article had received more than 25 citations.
