Today I defended my PhD! 🎓 I’m so grateful to Alisa, Miguel, and Adrian for their incredible support, and thoughtful feedback. My graduate school journey at BU has been truly formative, shaping my research and the person I am. Thank you for believing in me every step of the way!

Congrats to the newly minted ✨Dr. Carrera✨ (@matildecarrera.bsky.social) who successfully defended her brilliant dissertation "Turning Data Into Evidence in Human Origins Research" today with flying colors!! Woo-hoo 🙌 🎉🎉🎓 #PhDone Thanks to @adrian-currie.bsky.social for serving as external #philsci

Looking fwd to this workshop @ Caltech just before #PSA26 bringing together scholars from seismology & from history & philosophy of science to address relation between theory, observation, instrumentation, & progress in seismology.

As program committee chair, it's my pleasure to announce the program for the Asian Philosophy of Science Association's inaugural conference. We have a great selection of papers, and I'm very excited to see everyone in Singapore come July! Details: www.ntu.edu.sg/soh/news-eve... #philsky #philsci

I'll be presenting this work at PSA (San Diego, Nov 2026). The question is how to think about "formative" (aggregate) constructs and their empirical measurements in the social sciences (e.g., socio-economic status). The standard view (e.g., Borsboom 2005) requires constructs to be causes of...

Together w/ @miguelohn.bsky.social, I present the 2nd Foundations of Thermodynamics Workshop! We'll trace equilibrium reasoning from Archimedes, (post-)Newton, classical thermo, early QM, GR, to quantum thermo, bio, & econs. Abstracts: www.eugenechua.com/ftg2026-find... #philsky #philphys #philsci

In 1852, the astronomer Nils Haqvin Selander travelled past the Arctic to complete a massively time consuming and difficult project – measuring the shape of the Earth. But why was this so important? And why does measurement matter to science at all? Read the Essay by Miguel Ohnesorge to find out

The man who coined the term genocide, Raphael Lemkin, defined it as a greater atrocity than mass murder explicitly because it involves the intentional killing of a civilization.

Now out: How did earthquakes come to have a (quantitative) size? How can we quantify without experimental control? @cristianlarph.bsky.social and I answer both questions and show their implications for human science measurement. www.sciencedirect.com/science/arti... #philsci #histsci #seismology

My paper with @yichenluo.bsky.social has been accepted for publication at @thebjps.bsky.social! We argue that standard pictures of de-idealization are themselves idealized, and develop a practice-first account of de-idealization for validating idealized models. Preprint: philpapers.org/rec/LUODDB

Final days to submit an abstract to #PBCS2026! If you are an early-career scholar looking for a supportive environment to discuss your work & meet international peers, consider applying!

Now out as preprint in Philosophy of Science. l argue that two central desiderata for measures often conflict: quantitativeness and responsiveness to stakeholder values, forcing a choice between them. The conflict poses a challenge for recent work on "legitimate" measurement. doi.org/10.1017/psa....

This week, Cristian Larroulet Philipi joins us to talk about measurement in the human sciences: why it can be more philosophically complex than in the physical sciences, and how it raises pressing questions about the role of numbers in psychology, social science, and policy #philsci #measurement

My student, Sebastian Rodriguez Duque, has just successfully defended his dissertation on the role of ethical and social values in measurement. Next stop: two-year postdoc at Cambridge U supervised by @annaalexandrova.bsky.social . Congratulations, Dr. Rodriguez Duque! #philsky #philsci

The only possible way to round off the @ri-science.bsky.social Geophysics conference was to stick the attendees in Faraday’s lab 🤷🏻‍♀️ Thank you all so much for coming! @miguelohn.bsky.social @alisabokulich.bsky.social

Had a fantastic time yesterday at Ri as part of the "Decoding our Planet" workshop beautifully organised by @katysduncan.bsky.social and @miguelohn.bsky.social More info here: www.aip.org/history/deco...

Thank you @katysduncan.bsky.social and @miguelohn.bsky.social for convening such a wonderful discussion meeting on #histsci and #geophysics at @ri-science.bsky.social, and a great keynote from @naomioreskes.bsky.social

A wonderful talk tonight by @naomioreskes.bsky.social at the @ri-science.bsky.social on how Navy secrecy of oceanographic data impeded rise of plate tectonics.

I'm glad to be one of the contributing museum professionals at this

On Monday, the Royal Institution is hosting a workshop on the #histsci of geophysics, with a livestreamed keynote by @naomioreskes.bsky.social on plate tectonics. Read @katysduncan.bsky.social on how she and @miguelohn.bsky.social put the event together, and see who's presenting here:

Think you know the history of plate tectonics? Think again 🌍 @naomioreskes.bsky.social explores why the US military shrouded this science in secrecy & what this reveals about scientific progress, politics and power… 📅 7pm 12th May @ri-science.bsky.social 🎟️ Tickets www.rigb.org/whats-on/ret...

Fantastic program now out for #HPS conference "Decoding Our Planet: The Making of Geophysics", bringing together scholars from history of science, #geophysics, & philosophy of science to explore how modern geophysics took shape in #19thC & 20thC, at the Royal Institution in London 12 May

Congratulations @jakobortmann.bsky.social ! This started as the MPhil dissertation in Cambridge HPS, right?

Only a *little* while since the end of the project, I'm delighted that the Board of Longitude book is available for order (publication date 17 April), and that it is a relatively modest £32 in paperback! #histsci www.cambridge.org/gb/universit...

Excited to see a sneak peek of the upcoming Ri program on May 12th: "Decoding Our Planet: The Making of Geophysics" on the origins of modern geophysics, the science investigating everything from gravity & magnetism to earthquakes, climate change, & plate tectonics. More coming soon... #HPS ⚒️

Looking forward to @naomioreskes.bsky.social keynote next month: "Rethinking the Origins of Plate Tectonics" @ The Royal Institution of Great Britain Tickets now available for in-person & livestream attendance! Monday 12 May 2025 7pm #HPS ⚒️ www.rigb.org/whats-on/ret...
