The 100 top researcher keywords at UCSF

I was looking to dig into some examples of collaboration patterns in different research areas, when I realized I didn’t even know the basics — what do UCSF researchers actually research?

UCSF Profiles uses PubMed data to extract MeSH keywords for every publication by every UCSF researcher in the system. We can use this to look at the most commonly used MeSH keywords across every researcher’s body of work. There are lots of caveats here (looking at all publications emphasizes past research interests over current ones; we’re not grouping related obscure MeSH terms with more popular ones; MeSH term assignment practices change over time; and this analysis ignores someone’s role as a first, middle, or last author). But this is certainly a start.

Here’s what I found, using the latest UCSF Profiles data:

  1. 98 researchers have HIV Infections in their top 5 MeSH keywords
  2. 53 researchers have Breast Neoplasms in their top 5 MeSH keywords

Every researcher at UCSF — by department

Co-authorship networks can help us understand internal research collaboration patterns at UCSF. I used data from UCSF Profiles to create a visualization of (almost) every researcher currently at UCSF, and how their intra-UCSF co-authorship networks break out by department.

This visualization by department bears some more investigation than the previous one by school. Department of Medicine researchers are all over, collaborating with a wide variety of external departments. But an initial visual inspection suggests that almost all major departments have co-authorship relationships with members of other departments; some, like neurology, appear to form large standalone clusters, while others, like radiology, are more enmeshed in the work of others. This visualization flattens complex relationships into two dimensions, but it’s a starting point as we work to understand how UCSF collaborates.

Every researcher at UCSF — by school

Co-authorship networks can help us understand internal research collaboration patterns at UCSF. I used data from UCSF Profiles to create a visualization of (almost) every researcher currently at UCSF, and how their intra-UCSF co-authorship networks break out by school.

Unsurprisingly, the School of Medicine takes up most of the space, and the visualization is probably most interesting in terms of what it might suggest about the smaller schools. Researchers from the Schools of Nursing and Dentistry form their own visible clusters, who often work with each other, but also have co-authorship relationships with researchers at the School of Medicine. But I was surprised by the School of Pharmacy, whose researchers form a main clusters in the bottom right, as well as additional clusters in the middle and top left, due to strong collaborative relationships with School of Medicine researchers.

Departmental BFFs: Which UCSF departments publish the most often together?

Batman and Robin smoking

Some UCSF departments work more closely together than others. I looked at co-authorship patterns in papers published between January 2012 and November 2013, based on data in UCSF Profiles, and pulled out the UCSF departments that collaborate the most frequently. The results aren’t necessarily surprising. The Department of Medicine is huge, and their cross-departmental collaborations make up 8 of the top 10 collaborations, measured by volume. On the flip side, smaller groups with research areas similar to others make up many of the most common collaborations, by percentage; for example, one-third of papers by researchers primarily affiliated with the Proctor Foundation for Research in Opthalmology are co-authored with researchers from the Department of Opthalmology. I wouldn’t have necessarily guessed, however, connections like that between nursing and psychiatry.

Top UCSF cross-departmental collaborations, by volume

  1. Epidemiology & Biostatistics + Medicine: 365 collaborative papers
  2. Medicine + Pediatrics: 139 collaborative papers
  3. Medicine + Psychiatry: 127 collaborative papers
  4. Neurological Surgery + Neurology: 115 collaborative papers
  5. Medicine + Pathology: 105 collaborative papers
  6. Laboratory Medicine + Medicine: 104 collaborative papers
  7. Medicine + Surgery: 99 collaborative papers
  8. Neurology + Radiology and Biomedical Imaging: 92 collaborative papers
  9. Medicine + Radiology and Biomedical Imaging: 90 collaborative papers
  10. Medicine + Neurology: 86 collaborative papers

Top UCSF cross-departmental collaborations, by percentage

  1. 64.8% of School of Nursing Dean’s Office papers are co-authored with Physiological Nursing
  2. 36.8% of Proctor Foundation papers are co-authored with Ophthalmology
  3. 33.8% of School of Nursing Dean’s Office papers are co-authored with Medicine
  4. 33.3% of Physiological Nursing papers are co-authored with School of Nursing Dean’s Office
  5. 33.3% of Institute for Neurodegenerative Disease papers are co-authored with Neurology
  6. 32.4% of School of Nursing Dean’s Office papers are co-authored with Psychiatry
  7. 29.8% of Physical Therapy & Rehab Sciences papers are co-authored with Radiology and Biomedical Imaging
  8. 27.5% of Physiological Nursing papers are co-authored with Medicine
  9. 25.0% of Epidemiology & Biostatistics papers are co-authored with Medicine
  10. 22.8% of Family & Community Medicine papers are co-authored with Medicine

Details: Data is drawn from UCSF Profiles, and is based on a list of all publications listed on PubMed published between Jan 2012–Nov 2013, focusing on those whose authors include groups of researchers that have primary affiliations to more than one UCSF department. We counted only those publications from researchers with a listed department, and for the purposes of counting top cross-departmental collaborations by percentage, only those collaborations that generated 10 or more papers during the time period. No attempt was made to account for the widely varying sizes and scopes of different departments, the fact that researchers may have multiple departmental affiliations, or the fact that some publications may have been authored before the researchers were affiliated with their current primary departments at UCSF.

HIV/AIDS research collaborations, visualized

Co-authorship networks give us a sense of the strength of research collaborations. We used co-authorship data to visualize how top HIV/AIDS research institutions worked with one another, based on publications from June 2012 to September 2013. UCSF collaborations are indicated via red lines.

Visualization details: Data includes all known publications related to HIV/AIDS between June 2012 and September 2013 that includes co-authors from two or more institutions. We map each author to their institution, and the size of each institution corresponds with the number of HIV/AIDS publications its members co-authored in that time; only the most prolific institutions are shown to ensure readability of the image. The width of the lines connecting institutions corresponds to the number of publications that include co-authors from both of these institutions. Collaborations with UCSF researchers are indicated with red lines. Colors indicate clusters of institutions that often publish collaboratively, based on network modularity.
