Congrats to all of the winners of the AI for Public Goods grants program!! So inspired to see the breadth of work being done on biodiversity, mental health, democratic engagement, and better funding mechanisms for public goods (very meta!).

I'm hiring for a machine learning data scientist & research assistant for summer 2025! Join me on a project on invasive species management with an innovative startup doing on-the-ground removal of environmentally destructive invasive animals. Paid, full-time w/ possibility to extend.
I'm hiring for a machine learning data scientist & research assistant for summer 2025!

Join me in working on a project on invasive species management, by predicting species risk and planning capture strategies. This work will be in partnership with an innovative startup that is working directly to capture environmentally destructive invasive species in the US.

This project will be working with a US-based conservation partner to build predictive machine learning models and design harvest strategies for the removal of invasive animal species. The primary goal is to develop usable ML models and optimization tools to inform practical environmental decision-making on the ground.

There will also be opportunities to extend this work into a research publication for a top-tier AI venue.

The project would be:
Paid, full-time internship for summer 2025
Possibility of extension beyond the summer (part-time or full-time)
Remote, but candidates should be authorized to work in the US
Supervised by Lily Xu, assistant professor at Columbia University

Ideal candidate background will include:
Strong background in CS, data science, and/or applied math
Experience developing machine learning models
Excellent coding skills in Python
Excellent writing and interpersonal communication skills
Genuine interest in conservation/sustainability
Nice to have: background in optimization methods
Nice to have: experience with GIS and geospatial data
Candidates would ideally have already completed an undergraduate degree, but exceptional undergrads will also be considered.

How to apply:
Please send a CV and 3–5 paragraphs of your background/interests via email to <lily.x@columbia.edu> with the subject line "Application: ML for invasive species management". 

Applications will be reviewed on a rolling basis.

Can we use RL to plan with combinatorial constraints? Our #ICLR2025 paper combines deep RL with mathematical programming to do so! We embed a trained Q-network into a mixed-integer program, into which we can specify NP-hard constraints. w/ brwilder.bsky.social, Elias Khalil, Milind Tambe
Our method combines deep RL with mixed-integer programming
for sequential planning with combinatorial actions.

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

Our paper on unlocking the value of ranger-based monitoring (RBM), now out in Conservation Letters! Our work is a practical guide on when RBM may be useful for biodiversity conservation and protected area management, with some hard-won lessons for implementing RBM effectively. 🐘🌳🪺🤳🥾🪖
Unlocoking the value of ranger-collected data for biodiversity conservation

Full article in Conservation Letters: https://tinyurl.com/rangersdata

1. Set clear monitoring goals
2. Avoid wishful thinking
3. Raw data have limitations
4. Consider human dimensions
5. Adapt to your team's capacity
6. Don't be distracted by technology
