Hi, I'm Sarah: a PhD candidate, engineer, water-lover, language enthusiast, and dreamer.
Let's create the world we'll grow old in.
I have spent my academic and professional career working in environmental engineering and science, focusing on life's most important chemical substance: water.
My professional experience ranges from designing low-tech water treatment systems on remote islands – where I was challenged to find the most effective solution for healthy drinking water in a low-resourced setting – to remote sensing and applications of machine learning algorithms on agricultural landscapes for regional to global studies on food security amidst climate change.
University of California, Berkeley
PhD. Environmental Science, Policy and Management (in progress)
University of Delaware
B.E. Environmental Engineering (2017)
I am currently a doctoral candidate at the University of California, Berkeley in the Department of Environmental Science, Policy, and Management. I also have a Designated Emphasis in Development Engineering. My current research focuses on water, agriculture, and global trade to understand the sustainability of global food systems. I use machine learning of satellite imagery, geospatial datasets, and biophysical modelling to link local agricultural production, land tenure, and natural resource use with the global networks they support. I use science as a tool for examining the little-known and connecting communities.
In my free time, I volunteer on the executive team of Engineers Without Borders San Francisco, mentor students looking to pursue careers in STEM, and work to build an inclusive community within the groups I am a part of.
