My first week at the University of Oregon

My new work home.

Last week was my first week as a Research Assistant Professor in the Biology and the Built Environment Center (BioBE) at the University of Oregon, and my first full week in Eugene.  Combined with the Energy Studies in Buildings Laboratory, our collaborative team of architects and biologists researches how to make buildings more efficient, sustainable, pleasant, and healthy.

Delta Ponds, along my new bike route to work.

My first day started auspiciously as I charted a new bike route to work, about 4.5 mi of which is along a path snaking next to the Willamette River.  It goes through several parks, and by a few small lakes and swamps which are home to dozens of species of birds, mammals, amphibians, and reptiles.  I haven’t seen any river otters yet, but I have been keeping a close eye out.

Arriving on campus, most of my first day, and first week, were spent visiting the various places around campus to get myself established as a new employee- obtaining my ID card and email address, filing out paperwork, attending orientation, and finding all the coffee places within walking distance of the building.  ESBL is renovating and expanding its offices across several large, pluripotent rooms to accommodate a growing research team, so I got a brand new standing desk, chair, shelving, and computers (on order), all to my specifications.  The flexibility of working position, screen size, and screen angle provided by my new station are comfortable and great for productivity, and it’s neat to design the new space into offices, meeting tables, and storage which are based on our personalized usage needs and preferences.  And of course, there is plenty of space for all the mementos and science toys I’ve accumulated.

Most importantly, my first week was spent acclimating to my new department and getting up to speed on the ongoing and planned projects.  BioBE and ESBL have dozens on ongoing or planned projects on the built environment, with a combination of building and biology facets.  Over the course of the summer, I’ll be writing several grants and organizing new projects that explore how building use, occupancy, and human habits affect human health and the indoor microbiome, as well as contributing to the BioBE blog,  providing building microbiome posts to Give Me the Short Version, and getting some older projects out for publication.  On top of that, I’m looking forward to exploring the Pacific coast and the Northwestern landscape, and availing myself of the Willamette Valley wine industry.

My review on Plant-Microbial Interactions in Agriculture got published!

A few months ago, I was invited to submit an article to the special issue “Plant Probiotic Bacteria: solutions to feed the World” in AIMS Microbiology on the interactions between agricultural plants and microorganisms.  As my relevant projects are still being processed, I chose to write a review of the current literature regarding these interactions, and how they may be altered by different farming practices.  The review is available as open-access here!

“Plant-microbial interactions in agriculture and the use of farming systems to improve diversity and productivity”

A thorough understanding of the services provided by microorganisms to the agricultural ecosystem is integral to understanding how management systems can improve or deteriorate soil health and production over the long term. Yet it is hampered by the difficulty in measuring the intersection of plant, microbe, and environment, in no small part because of the situational specificity to some plant-microbial interactions, related to soil moisture, nutrient content, climate, and local diversity. Despite this, perspective on soil microbiota in agricultural settings can inform management practices to improve the sustainability of agricultural production.

A collaborative project on sheep feed efficiency and gut bacteria was published!

I’m pleased to announce that a paper that I contributed to was recently accepted for publication in the Journal of Animal Science!

“Feed efficiency phenotypes in lambs involve changes in ruminal, colonic, and small intestine-located microbiota”, Katheryn Perea; Katharine Perz; Sarah Olivo; Andrew Williams; Medora Lachman; Suzanne Ishaq; Jennifer Thomson; Carl Yeoman (article here).

Katheryn is an undergraduate at New Mexico Institute of Mining and Technology who received an INBRE grant to support her as a visiting researcher at Montana State University in Bozeman, MT over summer 2016.  Here, she worked with Drs. Carl Yeoman and Jennifer Thomson to perform the diversity analysis on the bacteria in the gastrointestinal tract of sheep from a previous study.  These sheep had been designated as efficient or inefficient, based on how much feed was needed for them to grow.  Efficient sheep were able to grow more with less feed, and it was thought this might be due to hosting different symbiotic bacteria which were better at fermenting fibrous plant material into usable byproducts for the sheep.

Samples from the sheep were collected as part of a larger study on feed efficiency performed by MSU graduate students Kate Perz and Medora Lachman, as well as technicians Sarah Olivo and Andrew Williams, and Katheryn performed the data and statistical analysis using some of my guidelines.  This is Katheryn’s first published article, and one I just presented a poster on at the Congress on Gastrointestinal Function in Chicago, IL!
