Field notes from my first ESA meeting

From iDigBio
A couple of weeks ago, I attended my first Ecological Society of America meeting in Portland, which assembles a diverse community of researchers looking at system-wide processes.  It was an excellent learning experience for me, as scientific fields each have a particular set of tools to look at different problems and our collective perspectives can solve research problems in more creative ways.

In particular, it was intriguing to attend talks on the ecology of the human microbiome.  Due to the complexity of host-associated microbial communities, and the limitations of technology, the majority of studies to date have been somewhat observational.  We have mapped what is present in different animals, in different areas of the body, under different diet conditions, in different parts of the world, and in comparison between healthy and disease states.  But given the complexity of the day-to-day life of people, and ethics or technical difficulty of doing experimental studies in humans, many of the broader ecological questions have yet to be answered.

For example, how quickly do microbial communities assemble in humans?  When you disturb them or change something (like adding a medication or removing a food from your diet) how quickly does this manifest in the community structure and do those changes last? How does dysbiosis or dysfunction in the body specifically contribute to changes in the microbial community, or do seemingly harmless events trigger a change in the microbial community which then causes disease in humans? Some of the presentations I attended have begun teasing out these problems with a combination of observational in situ biological studies, in vitro laboratory studies, and in silico mathematical modeling.  The abstracts from all the meeting presentations can be found on the meeting website under Program.  I have also summarized several of the talks I went to on Give Me The Short Version.

One of my favorite parts was attending an open lunch with 500 Women Scientists, a recently-formed organization which promotes diversity and equality in science, and supports local activists to help change policy and preconceived notions about diversity in STEM.  The lunch meeting introduced the organization to the conference participants in attendance, asked us to voice our concerns or difficulties we had faced, encouraged us to reach out to others in our work network to seek advice and provide mentoring, and walked us through exercises designed to educate on how to build a more inclusive society.

500 Women Scientists at ESA, August 2017

My poster presentation was on Wednesday, halfway through the meeting week, which gave me plenty of time to prepare.  You never know who might show up at your poster and what questions they’ll have.  In the past, I’ve always had a steady stream of people to chat with at my poster which has led to a number of scientific friendships and networking, and this year was no different.  The rather large (but detailed) poster file can be found here: Ishaq et al ESA 2017 poster .  Keep in mind that this is preliminary work, and many statistical tests have not yet been applied or verified.  I’ve been working to complete the analysis on the large study, which also encompasses a great deal of environmental data.  We hope to have manuscript drafted by this fall on this part of the project, and several more over the next year from the research team as this is part of a larger study; stay tuned!

In preparation for the ESA conference next week

I’m counting down the days for my first Ecological Society of America (ESA) conference next week in Portland, OR.  Over the last few weeks, I’ve been diligently working to finish as much analysis as possible on the data from my recent post-doc, as I am presenting a poster on Wednesday, August 9th from 4:30 to 6:30 pm; PS 31-13 – Soil bacterial diversity in response to stress from farming system, climate change, weed diversity, and wheat streak virus.

Several of my new colleagues will also be presenting on their recent work, including a talk from Roo Vandegrift on the built environment and the microbiome of human skin, and one from Ashkaan Fahimipour on the dynamics of food webs.

The theme for this year’s ESA meeting is “Linking biodiversity, material cycling and ecosystem services in a changing world”, and judging from the extravagant list of presenting authors, it’s going to be an extremely large meeting.  It’s worth remembering that large conferences like these bring together researchers from each rung of the career ladder, and many of the invited speakers will be presenting on work that might have been done by dozens of scientists over decades.  Seeing only the polished summary can be intimidating, lots of scientists I’ve spoken to can feel intimidated by these comprehensive meeting talks because the speakers seem so much smarter and more successful than you.  It’s something I jokingly refer to as “pipette envy”: when you are at a conference thinking that everyone does cooler science than you.  Just remember, someone also deemed your work good enough to present at the same conference!

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!

2017 Congress on Gastrointestinal Function

I just got back from my very first Congress on Gastrointestinal Function, poster tube.jpga small meeting for  researchers with a specific focus on the gastrointestinal tract, which is held every two years in Chicago, Illinois.  The special session this year was on “Early Acquisition and Development of the Gut Microbiota: A Comparative Analysis”.  The rest of the sessions opened up the broader topics of gut ecosystem surveillance and modulation, as well as new techniques and products with which to study the effect of microorganisms on hosts and vice versa.  The research had a strong livestock animal focus, as well as a human health focus, but we also heard about a few studies using wild animals.

As I’ve previously discussed, conferences are a great way to interact with other scientists.  Not only can you learn from similar work, but you can often gain insights into new ways to solve research problems inherent to your system by looking at what people in different fields are trying, something that you might otherwise miss just by combing relevant literature online.  A meeting or workshop is also a great place to meet other similarly focused scientists to set up collaborators that span academia, government, non-profit, and industry sectors.

It was great to catch up with Dr. Ben Wenner, now at Purdue Agribusiness, and meet Yairy Roman-Garcia, grad student at the Ohio State University.

This year, I was excited for one of my abstracts to be accepted as a poster presentation, and honored to have the other upgraded from poster to talk!  Stay tuned for details about both of those projects in the coming weeks, and be sure to check this meeting out in April, 2019.

2016 Year In Review

Looking back

2016 started with a bang when I launched this site and joined Twitter for the first time!  For the first quarter of the year, I was a post-doctoral researcher in the Yeoman Lab in the Department of Animal and Range Sciences at Montana State University.  I was working on a total of eight grants, ranging from small fellowships to million dollar projects, both as a principal investigator and as a co-PI.  I was also doing the bioinformatic analysis for multiple projects, totaling nearly 1,000 samples, as well as consulting with several graduate students about their own bioinformatic analyses.

In late spring, my position in the Yeoman lab concluded, and I began a post-doctoral position in the Menalled Lab in the Department of Land Resources and Environmental Sciences at MSU.  This position gave me the opportunity to dramatically increase my skill-set and learn about plant-microbe interactions in agricultural fields.  My main project over the summer was studying the effect of climate and other stresses on wheat production and soil microbial diversity, and this fall I have been investigating the legacy effects of these stressors on new plant growth and microbial communities.  I have extracted the DNA from all of my Fort Ellis summer trial soil samples, and look forward to having new microbial data to work with in the new year.  Based on the preliminary data, we are going to see some cool treatment effects!

Over the summer, I attended the American Society for Microbiology in Boston, MA in June, where I presented a poster on the microbial diversity in organic and conventional farm soil, and the Joint Annual Meeting for three different animal science professional societies in Salt Lake City, UT in July, where I gave my first two oral conference presentations. One was on the effect of a juniper-based diet on rumen bacteria in lambs, and the other was on the biogeography of the calf digestive system and how location-specific bacteria correlate to immune-factor expression.

Thanks to a lot of hard work from myself and many collaborators, a number of research projects were accepted for publication in scientific journals, including the microbial diversity of agricultural soils, in reindeer on a lichen diet, and in relation to high-fat diets in mice, it also included work on virulent strains of Streptococcus pyogenes, and a review chapter on the role of methanogens in human gastrointestinal disease.

Looking forward

A whopping thirteen manuscripts are still in review at scientific journals or are in preparation waiting to be submitted! Some of those are primarily my projects, and for others I added my skills to the work of other researchers.  Editing all those is going to keep me plenty busy for the next few months. I’ll also be writing several more grants in early 2017, and writing a blog post about the Herculean task that can be.

I’ll be concluding my greenhouse study by March of 2017, just in time to prepare for another field season at Fort Ellis, on the aforementioned climate change study that is my main focus. In January, I’ll be spending time in the lab helping to process and sequence DNA from my 270 soil samples, and begin the long task of data quality assurance, processing, and analysis.  I’m not worried, though, 270 samples isn’t the most I’ve worked with and bioinformatic analysis is my favorite part of the project!

This year, I am hoping to attend two conferences that I have never previously attended, and present data at both of them.  The first will be the 2017 Congress on Gut Function in Chicago, IL in April, and the second will be the Ecological Society of America’s Annual Meeting in Portland, OR in August.  Both conferences will give me the opportunity to showcase my work, network with researchers, and catch up with old friends.

If 2017 is anything like the past few years, it’s going to be full of new projects, new collaborators, new skills, and new opportunities for me, and I can’t wait!  So much of what I’ve accomplished over the last year has been possible because of the hard work, enthusiasm, and creativity of my colleagues, students, friends, and family, and I continue to be grateful for their support.  I’d also like to thank anyone who has been kind enough to read my posts throughout the last year; it’s been a pleasure putting my experiences into words for you and I appreciate the time and interest you put in.  I look forward to sharing more science with you next year!

ASM Microbe 2016 was a blast!

For the last four days I was in Boston for the American Society for Microbiology (ASM) Microbe 2016 meeting.  The meeting is held in Boston on even years, and New Orleans on odd. 

The conference brings together all sorts of microbiologists: from earth sciences, to host-associated, to clinical pathologists and epidemiologists, to educators.  This year, there were reportedly over 11,000 participants! Because of the wide variety of topics, there is always an interesting lecture going on related to your topic, and it was a wonderful experience to be able to talk directly to other researchers to learn about the clever techniques they are using.  I posted about a tiny fraction of those interesting projects on Give Me The Short Version.

On Sunday, I presented a poster on “Farming Systems Modify The Impact Of Inoculum On Soil Microbial Diversity.”  I analyzed the data from this project for the Menalled Lab last year, and it has developed into a manuscript in review, as well as several additional projects in development.

One of the best parts of ASM meetings is that you never know who you are going to run into, and I was able to meet up with several friends and colleagues, including Dr. Benoit St-Pierre, who was a post-doc in the Wright lab at the University of Vermont while I was a student, and Laura Cersosimo, the other Ph.D. candidate from the UVM Wright lab who will be defending in just a few months!  I also ran into Ph.D. candidate Robert Mugabi, who is hoping to defend by March and in the Barlow lab at UVM while I was there.  Most unexpectedly, I ran into a A Lost Microbiologist who had wandered in from Norway: Dr. Nicole Podnecky, who I met at UVM back when we were undergraduates!

Of course, no conference would be complete without vendor swag.
