The CDC updated its vaccine page to claim "vaccines do not cause autism" is "not evidence-based" and studies were "ignored." This is an outrage. Decades of research have found no link. This isn't science, it's RFK Jr. using the CDC as propaganda. Children will die because of this.

We measure ecological resilience in terms of a few variables at a time with widely differing choices of variables for different investigators, with conflicting outcomes. We need strategies to navigate diverse and conflicting resilience variables.

Locally acquired Chikungunya virus infection on Long Island. Maybe time to dust off my many-times rejected Chik proposal...

We know that wildlife provisioning can promote or inhibit infectious disease spread, depending on things like food quality.

What about pathogen evolution? Using math with a focus on birdfeeders and house finches, we found that high quality food selects for higher virulence!

What is the role of AI in ecology? A great piece by a collaborator of mine discusses this thoughtfully, particularly with respect to analyzing sensor data.

When the same journal immediately loves paper A but rejects paper B without review and you know that paper B fits the journals goals better than A...

A good reminder that so much depends on the editors/associate editors/reviewers that you get and their perception that day! Gotta just try again.

Stressed by a crisis for public perception of science and elated by my Indiana Pacers forcing a game 7, I have been thinking about what sports teach us all about the uses of data and expertise.

A grant proposal, which I and others spent dozens of hours on, was returned without review today. This is because NSF will no longer be making awards through the Biological Integrations Institute solicitation.

I am disappointed and furious at this latest ripple of the massive attack on science.

I think there are valid criticisms of science but I prefer it to the alternative of "just making stuff up"

New paper: We know the minority of hosts hold the majority of macroparasites (aggregation). What about fungal pathogens? Turns out, they are MORE aggregated than macroparasites, lognormally distributed, and the distribution carries signatures of epidemic stage.

Dreamed I was giving a chalk talk for a faculty job interview and one of the faculty brought their six year old. The kid kept interrupting with impressively relevant science questions but just incessantly and my talk ended up going quite poorly.

My brain upon waking: Ok gotta prepare for that.

Postdocs don't usually get to watch faculty candidate chalk talks for confidentiality reasons. But postdocs really need to learn how these work to be competitive in the academic job market. Any ideas?

Conflicted when I see my 2 yr old petting an invasive spotted lanternfly extremely gently. 😆Good instincts kid. Just the wrong bug.
