Yesterday, after waking up to the news of the Mw 7.8 earthquake in Mindanao, Philippines, I spent the past 24 hours using science, coding, and demographic & housing data to estimate the post-earthquake regional risk.

Proceedings of the Fortieth AAAI Conference on Artificial Intelligence are now available to review online. The proceedings have been published in 48 consecutive issues, which are all available here: aaai.org/proceeding/a...

I'll be at the 40th #AAAI in Singapore, presenting two research initiatives that advance disaster risk science w/ geospatial artificial intelligence and Earth Observation data! See you! I'll also be looking for jobs!

🇵🇭 20th APRU Multi-hazards Symposium & Conference, Philippines Today, I presented our city-scale work, which is a fruitful collaboration with city disaster risk managers, EMI (a nonprofit scientific organization) in Quezon City, and our university.

👋 Curious about AI4ER-CDT research on dynamic & probabilistic modelling for spatiotemporal disaster risk assessment? I'll be online at @agu.org 2025 (#AGU25) in New Orleans, Louisiana, & Online World! 🗓️ 14:15-17:45 (CST), Tuesday, Dec 16th 🌐 iPoster: agu25.ipostersessions.com/Default.aspx...

At the Digital GreenTalents Award Ceremony 2025, 20 young researchers received this year's award for their work at the intersection of #digitalization and #sustainability. We're looking forward to seeing all the talents at the Summer School 2026! Learn more: digitalgreentalents.de/awardees-2025

Hello! Time for my year-ender updates, as I'm now in my final year as a PhD researcher at the University of Cambridge 🇬🇧 (mentored by Emily So, FICE, Christian Geiß, Robert Muir-Wood, Fouad Bendimerad) in applying AI & EO to the study of environmental risks (AI4ER) in the built environment (CURBE):

🌏 On the 𝗜𝗻𝘁𝗲𝗿𝗻𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗗𝗮𝘆 𝗳𝗼𝗿 𝗗𝗶𝘀𝗮𝘀𝘁𝗲𝗿 𝗥𝗶𝘀𝗸 𝗥𝗲𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝟮𝟬𝟮𝟱, we, at the University of Cambridge, have been conducting timely research in support of the 2015-2030 UNDRR #Sendai Framework using #AI and #EarthObservation data. #DRRday 🧵

"In the years following a disaster, do affected communities reduce their future risk by avoiding the construction of vulnerable structures, or do they rather return to settle in pre-identified danger zones, even after experiencing their devastating impacts firsthand?"

Our non-peer-reviewed preprint "Deep Conditional Census-Constrained Clustering (DeepC4) for Large-scale Multitask Disaggregation of Urban Morphology" is now available on arXiv! This work is the highlight contribution of my first-year PhD-ing, which deals with "spatial auditing".

Just also sharing my #AGU24 Photo Contest 📸 entries here, and also showcasing how beautiful my 🇵🇭 is. These were taken while I was having a writing break and walking around our neighborhood - farms! #PhDChat See you next week, everyone! Captions in the ALT textboxes.

One week before #AGU24 @agu.org ✈️ in Washington, D.C., let me share a big update of our PhD work at AI4ER-CDT, presenting 🥁 "DeepC4", from being specific a few months ago to a possibly flexible & general approach in modelling our urban fabric. Kitakits! See you!

@acescicomm.bsky.social and I met here and realized we both were looking for more #SciSky #PinoyScientists 🇵🇭🧪! So, we joined the starter pack bandwagon ... 😅 We also want to highlight folx and what they do ✨ Please fill out the form if you're interested in joining: forms.gle/h4WUpE1T9jHt...
