Always learning, always sharing, how trees adapt today, and how they’ll keep adapting as our world changes. Thanks #EVOLTREE for the opportunity to be part of such an amazing conference

Just published! 🌿 Our new study uncovers how hybridization and climate selection interact to shape stomatal trait evolution across six Populus contact zones. @jillahamilton.bsky.social If you’re curious about how hybridization influence adaptive trait variation, take a look doi.org/10.1111/nph....

Very much a #proudPI moment when your PhD students @michellezavala.bsky.social and @krlopicc.bsky.social give such lovely presentations of their research. So glad to have the opportunity to join the #EvolTREE meeting and share our ongoing research and learn from diverse systems across Europe.

Amazing field trip with the #EvolTREE conference. Wonderful to learn of the new breeding efforts in Cork oak and Holm oak, integrations of new technologies, and degree of monitoring for conservation that has leveraged, expanded, and established leadership in genetic conservation

Congratulations to @michellezavala.bsky.social on the publication of one of her PhD. This research builds on #NSF-funded #PopUpPoplar research using WGS and replicate common gardens to understand how climate and hybridization influence stomata evolution nph.onlinelibrary.wiley.com/doi/10.1111/...

I am looking to hire a postdoc interested in combining genetics and evolution to understand why telomeres vary so much in plants. My group has been developing Mimulus a genetic model for studying plant telomeres and we have really cool research brewing. Please check ad for detail. Deadline is 12/31.

Are you interested in pursuing groundbreaking research and gaining world-class training in plant biology in a supportive community amidst the beauty of Happy Valley? Consider applying to the the Plant Biology PhD Program! Applications due December 1: www.huck.psu.edu/graduate-pro...

It is official! DR. @michellezavala.bsky.social defended a very impressive dissertation today!! With friends, family, stomata cookies, and Ecuadorian Guinea pigs cheering her along! We understand so much more about the consequences of hybridization to the evolution of physiological traits!! #proudPI

Hamilton Lab members are excited for the upcoming #EvolTREE meeting! Kyra will present our genetic conservation program in black ash , Michelle will discuss climate, hybridization, and stomatal evolution (tinyurl.com/y5rwu8eu), and I will discuss genomics-driven monitoring. Hope to see you there!!

I recently moved my lab to Purdue University and am looking for graduate students. We are working at the interface of population genomics, quantitative genetics and functional genomics to understand how plants adapt to extreme environments. Reach out if you would like to discuss potential projects.

Thanks so much to @arcastilla.bsky.social, the entire Castilla Lab and the Department of Biology for such a wonderful visit to Oklahoma State! Such fun scientific conversations and beyond!! with great ideas generated with faculty, graduate and undergraduate students! Leaving inspired!

Hello! I’m recruiting three graduate students (MS or PhD) to start in summer or fall 2026 . Projects are broadly focused on the ecology, restoration, and management of rangelands, deserts, and forests. Please share! Lab website: functionalrestoration.nmsu.edu

First (annual?) Hamilton lab off-grid camping trip to Bald Eagle State Forest. Good company, scenery, s’mores and so much more. Food for the soul!! I’m a very #luckyPI to work with this amazing group!

A little adventure through the roads around State College this evening while the sky put on a show #happyvalley #nofilter

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Super excited about this new Open Rank tenure-track faculty search for the MSU Plant Resilience Institute. We successfully hired two excellent new faculty in our last search and we are hoping to build on that success with this search. careers.msu.edu/jobs/assista...

‘New hope’: ash trees rapidly evolving resistance to dieback, study reveals

Excited to be in Ottawa this week for the Canadian Forest Genetics Association meeting!! Great to wake up and walk around the national capital to start the morning ❤️🇨🇦

Super sad to be missing out on #Botany2025, but Hamilton Lab is represented by @sammymuraguri.bsky.social - be sure to drop by his poster to learn about the genomic architecture of adaptive introgression across repeated contact zones between two sister Poplar species #PopUpPoplars
