Ram Lab

We study evolution, ecology, cultural evolution, and epidemiology, using mathematical, computational, statistical, and machine-learning models and collaborations with empirical biologists. See the research page to read more about our research interests and projects.

Our lab is in the School of Zoology in the Faculty of Life Sciences at Tel Aviv University.
We are also affiliated with the Sagol School of Neuroscience and the Safra Center for Bioinformatics at Tel Aviv University.

If you are interested in joining us, please email Yoav.
