Our paper (Brieuc Lehmann is the first author) is now online in Genetics.

I want to try something again at #ASHG25 this year: I'll block some time on Thursday and Friday afternoons to meet with trainees who would be interested to chat on any topic.

I did this last year and it was great to meet a whole bunch of new people, at all career stages!

Excited to share a new pre-print in collaboration with @sebastianschreiber.bsky.social, "Using Modern Coexistence Theory to understand community disassembly"! We set out to understand how techniques used to study coexistence can be extended to understand community disassembly. (1/X)

The goal was to understand biogeography, so we sequenced transcriptomes for the new species, and several others, and built the largest-yet Caenorhabditis phylogeny. The most common Pohnpeian species (C. pwilidak sp nov) is sister to a Hawaiian endemic clade!

SINGER, our ARG inference method, is finally published and freely available online:

It was a long journey – 16 months from initial submission to acceptance. Is it just me, or has peer review gotten more arduous lately? 4+ rounds of review isn't so unusual these days...

The constant barrage of terrible news on bluesky has made me feel weird about promoting papers, but people in the lab have been doing so much amazing work over the past few months that I want to share a few brief teasers/links:

Please share broadly: I am looking for a postdoctoral fellow to work on a collaborative project on the temporal population genomics of invasive Capeweed (using contemporary and herbarium genomics), with ‪‪@shaky-dingo.bsky.social‬ and colleagues

A nice profile of the wonderful Annie Schmitt

Sanaa Khan from @katelaskowski.bsky.social lab talks about when males of Atlantic mollies transfer their sperm to sperm parasites Amazon mollies. An amazing talk with incredibly cool results!

I'm looking to recruit a PhD student to study patterns of local adaptation and introgression across the spruce hybrid zone in the Rockies near Calgary. Projects can include field work, bioinformatics, pop gen theory, or comparison to plant/ conifer species

And if you are looking for the latest version of the package or find it useful and want to make a feature request, we are actively developing the visualizer over on GitHub at github.com/kitchensjn/t....

6/6

Whether you are looking to get a better grasp on how these graphs are structured or communicating findings from your latest ARG inference project, we hope that tskit_arg_visualizer becomes a useful addition to your research toolkit!

5/6

After spending the first half of my Ph.D. hand-drawing so many ARGs in my notebooks for sparg, I wanted a method to pair alongside my research that would help me better explore these graphs.

4/6

Both views are fully interactive, giving users the ability to reposition nodes and highlight individual trees within the graph structure.

3/6

The visualizer offers two views: 1. draw() - displays the full graph (shown in A and B) and 2. draw_node() - focuses on a subgraph around a focal node, useful when ARGs are too large to view all at once (shown in C).

2/6

Excited to share our new preprint for the tskit_arg_visualizer Python package! ARGs can sometimes feel like a black box, so
@yanwong.bsky.social and I have been developing a method to programmatically drawing these graphs.

Excited to be at the ESA Annual Meeting! I am presenting Tuesday morning on understanding processes of community disassembly and secondary extinctions using modern coexistence theory. Also would love to chat with folks at the conference so feel free to message if you’d like to chat!

Please share this widely and encourage students to apply! Many of our current graduate students were recruited through this program -- happy to answer any questions and connect with students

Poster presentation done at my first conference ever !( #Evol2025 )

Thank-you to everyone who came by !

Pleased to share that my first, first-author publication was published yesterday in @pnas.org ! We (me + @jrossibarra.bsky.social) did a little bit of detective work to better understand the age and origin of a mutation that played a key role in maize domestication. doi.org/10.1073/pnas... (1/n)

Trip report from our recent excursion into Emigrant Wilderness over Memorial Day Weekend! james-kitchens.com/blog/upper-c...

I'm excited to share our new preprint on the molecular evolution of heterodichogamy in two wingnut genera of Juglandaceae. Heterodichogamy features two morphs synchronously alternating male and female flowering phases in time to generate disassortative mating.

Hey! Super excited to be hosting this SMTPB Grad and Postdoc research showcase. The first session is happening on Monday (March 5th)

If you have a postdoc position or a job to advertise in this session, please feel free to reply in this thread or email me ([email protected])!!
