The last paper from my PhD is out today in JGR Planets! we looked at how Titan's topography can interact with tidal and possible tectonic stresses to generate fractures, which could erode over time to produce icy sediment and provide fresh surface area for hydrocarbon interxn

Topographic Stress as a Mechanical Weathering Mechanism on Titan
Stress perturbations induced by topographic features on Titan can lead to fracture in its icy crust, enhancing mechanical weathering This mechanism could help generate sediment on Titan Titan's ...

fun pics from the -26C freezer this week, despite the 35+C heat outside: 50x magnification of saltwater trapped between pure ice crystals, with higher (~2%, left) and lower (~0.5%, right) salinity.

something fun: have accepted a humboldt postdoc fellowship with DLR Berlin starting early 2026!

perhaps one day we will see major news media accurately saying less spending = people lose jobs/services/lives, instead of endorsing the right-wing fiction that government spending works like a regular bank account and less spending = good. but surely whatever is happening now is ok too

Here's how to ask your Senators for *specific* funding levels for NASA, NSF, and Department of Energy Office of Science. It's simpler than you think! @aas.org @policy.aas.org 🧪🔭

crowdfunding my #woke #dei radical marxist ice geophysics research by asking every american who thinks that antarctica even still exists for $0.0005 (one twentieth of one cent) per year... If only there were a better way....

squished a meteorite for the people (planetary deformation modelers). found some energetically dissipative mechanisms that are present in response to tiny stress changes, which could be a cool source of heat for smaller moons in particular. preprint here. doi.org/10.22541/ess...
