I'm excited to share my latest preprint: Stochastic modeling of yield losses due to bacterial leaf streak on corn. Our study examined the impact of bacterial leaf streak (BLS) on corn yield. Thanks to Prof. @edelponte.bsky.social and Dr. Adriano. Preprint: osf.io/8zq4y_v1 Code: lnkd.in/d2DFmpje

In 2023 I painted coffee rust, caused by the fungus Hemileia vastatrix This is one of my favourite plant disease paintings and was used for the cover @edelponte 's book Plant Disease Epidemiology (R4PDE) r4pde.net www.hgpenningtonart....
The painting shows a coffee branch, with 10 leaves emerging in pairs, one on each side of the stem. Counting down from the terminal bud, the base of the fourth leaf pair has a cluster of finishing flowers, the fifth leaf pair has seven green coffee berries, and where the sixth pair would have been, there are a further six berries.  The adaxial (upper) surface is displayed  for eight of the 10 leaves, while the abaxial (lower) surface is shown for the remaining two.

There are yellow chlorotic patches on the adaxial (upper) leaves, and dark brown necrotic areas in the largest lesions. 

On the abaxial (lower) leaves, bright orange areas in the centre of the yellow lesions indicate areas of sporulating rust.

This time of year, the campus feels quiet and lifeless as students have yet to return. Yet, the beauty of Viçosa's campus remains vibrant, and I look forward to seeing these sidewalks bustling with life next week.

Missed opportunity!! We edit a lot of cover letters to address exactly these points––it's your chance to explain why your paper is cool, so don't blow it by pasting in your abstract (which should also explain why your paper is cool but differently!).

More opportunities! Besides a PhD student (other post) we are looking for postdocs! One on Quantitative Disease Resistance mechansims! One on Population Genomics of barley pathogens! The positions can start Feb 2025. For extremely well-fitting candidates can delay the date.

The recent CAPES normative banning fully online courses and asynchronous activities in Brazilian graduate programs is a setback for modern education. It limits opportunities for internationalization, like the remote course (epidemiology) I offer in English, attended by students from abroad 1/3

It was great fun working with Emerson on this paper. Meta-analysis has occupied a major portion of my research time over the past 15+ years. Many plant pathologists are now seeing the benefits of this approach to quantitative research synthesis.

A few things I've been working on lately: elmer, elmer.tidyverse.org, is a new package to make it easier to work with LLMs (hosted and local) from #rstats. It includes helps for structured data extraction and tool calling, and an easy way to upload a plot. Joint work with Joe Cheng.
