Officially promoted to Associate Professor today, wow time has gone by so fast! I would not be here without the inspiration and help of everyone that shared a joy for discovering the evolution of plant water relations. Can't wait to keep botanizing Purdue BPP Purdue Agriculture

That's my bro!

Congratulations to Professor Tim Brodribb, who has been elected as a Fellow of Australian Academy of Science. Tim's groundbreaking research has revolutionised our understanding of plant behaviour.🌱 Please join us in congratulating him.🔗Read more: utas.au/3d

Our paper on root system vulnerability has been published in New Phytologist! So excited to have worked with Dr. Kate Johnson Vanessa Tonet Ibrahim Bourbia and Chris Blackman in the Brodribb Lab. Visit doi.org/10.1111/nph.19… for more. Thanks to ARC Centre of Excellence for Plant Success and University of Tasmania

I’ve had such a wonderful time and discovered some amazing things in Tasmania!

New paper is out!

Angiosperm stomata do not respond continuously to rising VPD but often start to close only once a threshold VPD is crossed. We found that this is linked to the triggering of abscisic acid biosynthesis at the threshold VPD, which then closes the stomata academic.oup.com/plphys/advance…

We have found that abscisic acid biosynthesis is deactivated under long-term drought in species that have evolved highly embolism resistant xylem, this causes the peaking-type ABA dynamic onlinelibrary.wiley.com/doi/10.1111/pc… Congratulations Joel A. Mercado Reyes!!

When a sort of plant is very thirsty, the small holes on its leaves kindly shut down to save water. It's like when you close your mouth to stop drinking the whole juice box at once.

Successful defended my PhD about the physiology of deciduous leaves. Thanks to McAdam lab for being the best advisor in the world.

Congrats to ⁦Cade Kane⁩ from ⁦Purdue BPP⁩ on a successfully defense! He is the 1st PhD student from the McAdam lab (⁦McAdam lab⁩)!! He’s already published a few chapters & is gearing up to submit the last two before he “leaves” us for his postdoc in Jan!

Check out my most recent paper investigating time-lapse imaging to visualize freezing in-situ leaves Plant Cell & Environment doi.org/10.1111/pce.15…

Time-lapse imaging and thermocouples reveal that Lonicera xylem sap freezes at -2°C in situ, compared to 0°C ex situ. Slow, natural freezing allows for photosynthetic recovery, while rapid freezing inhibits it. onlinelibrary.wiley.com/doi/epdf/10.11… Wiley Plant Science #OpenAccess

It is a pleasure to have (finally!) contributed to the esteemed anthology of literature questioned by Karlheinz Hahn
