We found that even limited sequence data can meaningfully improve carrier inference when integrated with other data. By linking patient mobility, genomics, EHR, and culture data, we move closer to spotting the silent spreaders of AMROs in hospitals and intervening more strategically. 5/

The inference framework was validated using both simulated outbreaks and real-world data on carbapenem-resistant Klebsiella pneumoniae in a large hospital. Inference with multiple data streams can better identify carriers and inform more effective target interventions. 4/

We then built an inference framework that combines patient movement, clinical cultures, whole-genome sequencing, and risk factors in electronic health records to estimate who is likely colonized. 3/

Asymptomatic carriers drive silent transmission of AMROs in hospitals, but they’re hard to detect due to sparse observations. We developed an agent-based model informed by real-world time-varying contact networks in hospitals to simulate AMRO transmission and community importation. 2/

Hurricane Evacuation Patterns Differ Based on Where the Storm Hits
People in coastal areas with frequent hurricane exposure are more likely to travel out of harm’s way compared to people in inland areas who are more likely to stay put.

As hurricanes are becoming stronger and expanding their reach due to climate change, people need to be prepared for disasters they've never experienced before.

A new era of floods has arrived. America isn’t prepared.
A Washington Post investigation reveals why so few people evacuated in the state hit hardest by last year’s deadliest disaster.

This is a great opportunity to join an interdisciplinary team in NYC working on infectious diseases, modeling, and health. The position will remain open until filled. The first round review will begin on November 15th. The starting time is flexible. Please reach out if you have any questions!
