Joining our lab at University of Arizona


Winter 2022

The lab is currently seeking one postdoctoral scientist for a NASA funded project (described below) to start in Winter 2022 (Jan 3 preferred, but earlier start dates are possible.)

"Understanding flood risk in human altered landscapes from cities to farms: inferences from satellites and machine learning."

This project leverages inundation observations to understand extreme flood risk in human-modified landscapes, specifically in urban and agricultural areas. We will use commercial and public sensors to i) map maximum inundated area for extreme flood events, ii) quantify flood risk at watershed scales, and iii) estimate of flood return periods at household scales (30m resolution). These objectives will be reached by using deep learning approaches to map floods and damage, and estiamte return periods with Bayesian Hierarchical Models. We will use optical and radar satellites, including MODIS, Sentinel-1, Planetscope, and the HLS (Harmonized Landsat Sentinel-2 dataset), comparing satellite-based flood maps and return period predictions for Bangladesh to those produced by the Bangladesh Flood Forecasting and Warning Centre (from a physically-based model). We will discuss applications for insurance and climate risk financing with collaborators in Bangladesh. The post doc will work closely with Dr. Tellman and collaborators Dr. Upmanu Lall at Columbia and Bangladeshi collaborator Dr. Saiful Islam, as well as staff at the Bangaldesh Flood Forecasting and Warning Center. We plan to visit Bangaldesh during the project. Opportunities to collaborate across other NASA projects at our lab (for megacity flood mapping and infrastructure mapping with deep learning) will be welcomed and encouraged! Post docs in our lab will be given 20% time to dedicate to personal projects, publishing their dissertations, and applying for grants to further their career.

Human Environment Geography

I am a human-environment geographer seeking to understand, map, and mitigate the causes and consequences of global environmental change with and for marginalized populations. I engage in a wide array of disciplines and methods from land system science, to hydrology, to the social sciences. I will be Assistant Professor of Geography at the University of Arizona in August 2021 and am recruiting PhD students and postdocs that are fully funded! Send your CV, a piece of writing you are proud of, and an expression of interest to my email. PhD and Master's applicants should have either expertise in or a willingness to learn satellite image analysis, programming, and quantitative skills. Applicants must also demonstrate a commitment to building a more socially just world. We are devoted to building a diverse, inclusive, and anti-racist lab. Women and all expressions of gender identity, Black, Indigenous, and people of Color, LGBTQ people, and individuals with disabilities are especially encouraged to apply. Funding support for application fees is available for students from low and middle income countries- please indicate this in an email to me. PhD applications will be accepted for Fall 2022 in January 2022.


Arizona is beautiful, affordable, and diverse socially, geologically, culturally, and ecologically, with plenty of opportunities for outdoor recreation, activism, and volunteering. Tucson has a pioneering climate justice policy and a great local food scene!
