I am seeking a postdoc to conduct studies on phenotyping crop physiology and growth using high-throughput techniques combined with AI/ML. An ideal candidate is a motivated individual with relevant skills or a strong desire to learn. If interested, feel free to DM me for more details.

I am very happy to see our paper out! Plant responses to many stresses are mediated by the same processes and I have long wondered how this relates to hotter droughts.

Mapping the roots of saguaros at Saguaro NP. The DBG is partnering with SNP and the U of Wyoming to map the roots of saguaros. Knowing the distribution of saguaro roots reveals how sensitive they are to droughts, and to what extent these iconic plants engineer the water cycle of desert ecosystems.

David Lynch gave us the language we needed to better articulate the indescribable strangeness of our shared reality. “Lynchian” is so overused because it’s a viscerally understandable word without any known synonyms. I can’t imagine a more beautiful artistic legacy than that.
