I’ve been a researcher since Juy 2010, when I started graduate school, and my first peer-reviewed journal article was accepted in 2012. This summer, I reached 50 peer-reviewed publications, including research papers and reviews. Since I started publishing, I’ve been in grad school, two one-year postdoc positions, one two-year research assistant professor position, and one four-year-and-counting assistant professor position, and my research areas of focuses have shifted 5 or 6 times since then to keep pace with the job I was in at the time. To capture that diversity, I made a word cloud of my publication list, including authors, titles, and journal names:
Unsurprisingly, most of my top keywords include the microbes I’m focusing on (bacterial), the animals I’ve worked with (moose, Alces), the sample types I’ve worked with (rumen, soil), and the methodology I use (seqeuencing).
None of this would have been possible without hundreds of researchers that I have worked with over the years. Here are a few of the names that pop up in theat wordcloud because I have published so often with them:
- Carl Yeoman, Montana State University, who was my post-doc advisor for a year and who I’ve continued to publish with on various projects. We’ve co-authored 11 papers!!
- Andre Wright, my PhD avisor, who has since moved into non-research roles, also with 11 co-authored papers!!
- Fabian Menalled, Montana State University, who was my post-doc advisor for a year and who I collaborated with for many years on projects which sprung from that first year. We have 7 co-authoured papers!
- Jean MacRae, University of Maine, and I have collaborated on a handful of different projects since I joined UMaine and have co-authored 4 papers with another currently in review.
