Aging drives a program of DNA methylation decay in plant organs Plants display a wide range of life spans and aging rates. Although dynamic changes to DNA methylation are a hallmark of aging in mammals, it is unclear whether similar molecular signatures reflect ra...

Absolutely delighted that our paper on epigenetic dynamics during plant aging is out today in Science!

It'd be good to chat Dan. I don't know the answer, but it'd be cool to pick the family apart as a next step and see if we can extend the phenotypes we have and find more.

Imputation integrates single-cell and spatial gene expression data to resolve transcriptional networks in barley shoot meristem development - Nature Plants Spatially resolved gene expression during barley development was done by integrating an scRNA-seq dataset from cells with unknown position with spatial transcriptomics. This dataset is publicly availa...

It's finally out!...
Using single-cell and spatial transcriptome data, and data imputation, we created BARVISTA, a website able to perform almost genome-wide information on gene expression profiles at single-cell resolution in barley spikes!

Four panel comic with two figures: Figure 1: 'So how's mid-career?' Figure 2: 'Well... I wonder shy I get passed over for opportunities but am very afraid of taking them. I alternate between imposter syndrome and wondering why others can't keep up. I have the means and skills to pursue personal interests but not the time or interest to do so. I marvel at how far I've come and lament that I'm not further. I'm way more secure but worry about all kinds of things. I have the power to change the world but am far less sure it's worth it. So pretty good really?"
