Welcome to join the Columbia Mailman Seminar Series on Infectious Disease Modeling, featuring Prof. Mauricio Santillana from Northeastern University & Harvard on 10/7 Wed at 12 pm ET! This is a hybrid event with both in-person and Zoom options, open to the public. Please register using the QR code!

🏛️ We’re kicking off the first seminar of the new academic year with @senpei.bsky.social He will discuss how to use mathematical models to uncover hidden disease transmission, improve forecasting, surveillance, risk assessment, and outbreak control Details 🔽 www.lshtm.ac.uk/newsevents/e...

🌪️ We’re launching the Hurricane Mobility Tracker, an interactive dashboard showing how population movement changes before, during, and after hurricanes, using cellphone-derived foot-traffic data. Check it out and share with anyone who may be interested! 🔗 hurricane-mobility.fly.dev

I’m delighted to be an invited speaker at the ARCANE Workshop on Modeling Antimicrobial Resistance, October 19-21, 2026 in Paris. The call for abstracts is now open! Submit your abstract here: arcane.sciencesconf.org Thanks to the organizers. Look forward to seeing many colleagues in Paris!

Congratulations to Dr. Han Yong Wunrow on successfully defending his PhD in Applied Math at Columbia APAM! Han Yong is the first PhD student I co-supervised. His research advances data-driven ID modeling using data assimilation and AI. Excited for his next chapter at Google!

Congratulations to Fintan Mooney, our brilliant doctoral student at Columbia EHS, for passing his qualification exam today! Fin is passionate about research on extreme weathers and population health. We look forward to his impactful works in this space!

Great weather in Boston. Excited to be at NetSci Conference 2026 this week! Our group has two presentations - welcome to stop by and chat. Looking forward to the fantastic science near the Charles River!

👇 Great opportunity to work with Prof. Alan Cohen @cusciofhealth.bsky.social and me to develop novel metrics of biological health at the whole-organism level. Please reach out if you are interested!

Important work from @dalarsen.bsky.social on wastewater surveillance! Genetic variability in wastewater is a better indicator of community transmission. A great reminder that existing surveillance data often contain far more information than we currently extract. www.science.org/doi/10.1126/...

Really enjoyed presenting at the Columbia Global Research Stabilization Fund Spring Showcase today. RSF’s support last year was critical in keeping our epidemic forecasting work moving. Inspired by the breadth of research and looking forward to what comes next!

Join ESPIDAM 2026 — the European Summer Program in Infectious Disease Analysis & Modelling! A unique training opportunity for early-career researchers in epidemic modelling 🦠📊 ⏳ Early bird deadline: March 31 www.su.se/english/divi...

Come work with me at Penn State on the dynamics of pathogen elimination. We're hiring up to two positions to support our work on measles/rubella and foot and mouth disease elimination @ciddpsu.bsky.social

It was a great pleasure to host a visit by @theferrarilab.bsky.social ! Super interesting talk and tons of impactful works on measles and rubella.

Honored to be elected as a Steering Committee Member of the MIDAS network @midas-network.bsky.social Grateful to give back to a community that has shaped my career, and looking forward to supporting early-career investigators and strengthening engagement with international scholars.

Two postdoc positions open at SUMOC (Sorbonne Université | INSERM), Paris, within the EPIcx lab. 🦠 Network epidemiology of healthcare-associated infections (ARCANE) 🧠 Coupled behavior–disease modeling (PREVIX) 2-y positions | Start June 2026 #epidemiology #networks #matrices

Welcome to join Columbia Mailman seminar series on infectious disease modeling featuring Prof. Matthew Ferrari @theferrarilab.bsky.social from Penn State on 3/17 Tue at 12 pm EST! Open to the public over Zoom. For more information and registration: events.columbia.edu/cal/event/ev...

Welcome to join Columbia Mailman seminar series on infectious disease modeling featuring Prof. Virginia Pitzer from Yale on 2/10 Tue at 12 pm EST! Open to the public over Zoom. For more information and registration: events.columbia.edu/cal/event/ev...

Presymptomatic transmission is a key determinant of the controllability of respiratory viruses. This nice study used household data to quantify presymptomatic transmission of influenza and Omicron. Important findings with implications for modeling and control. www.nature.com/articles/s44...

Dont miss the ESPIDAM summer program in June 2026 in Stockholm, covering many key concepts for ID modelling: stochastic models, AI for ID control, nowcasting and forecasting, phylodynamics, data analysis, network models, within-host models, health economics www.statistics.su.se/english/divi...

2025 was a challenging year for many of us. As the year comes to a close, let's pause to recognize and celebrate every accomplishment and milestone, big or small. Each step forward matters. As we head into 2026, let’s keep climbing with aspiration, resilience, and strength!

I am teaching Introduction to Network Science for a third year at Columbia Mailman! @cupublichealth.bsky.social Very grateful to have positive evaluations from students with diverse backgrounds. Welcome to join this small-size, engaged course if you are interested in networks and systems thinking!

Very interesting study on respiratory virus transmission in schools! "Prolonged exposure in shared, poorly ventilated spaces, which potentially includes several infectious sources, drives respiratory virus transmission more than close contact." www.nature.com/articles/s41...

Welcome to join Columbia Mailman @cupublichealth.bsky.social seminar series on infectious disease modeling featuring Prof. Mark Jit @markjit.bsky.social from NYU on 12/16 Tue at 12 pm EST! Open to the public over Zoom. For more information and registration: 👉 events.columbia.edu/cal/event/ev...

Grateful to @natcomms.nature.com for featuring our AMRO inference study as one of the Editors’ Highlights in #PublicHealth: www.nature.com/collections/...

Sunny and warm in San Diego. Preparing for #EPIDEMICS10 next week!

A super interesting study on how ants alter their nest networks to prevent epidemics! Network topology metrics were used to measure the effect on disease transmission. www.science.org/doi/full/10....

Excellent work on the ecology and spread of H5N1 in North America 👉

Fantastic talk by Dr. Holden Thorp, Editor-in-Chief of Science, on the future of scientific research. Especially inspiring to hear how many scientific giants pushed forward even when others tried to stop them. In times of uncertainty and challenge, do the work.

Our group is presenting at the MIDAS Network Annual Meeting! I will present on reconstructing the early spatial spread of pandemics in the US. Dr. Qing Yao will discuss the use of GNN to predict adaptive mobility for improving epidemic forecasts. Welcome to join us! @midas-network.bsky.social

Oof, this is a tough one...
