Danielle Tijerina is a PhD student in Hydrology at the Colorado School of Mines in the Integrated Groundwater Modeling Center. Her research focuses on the use and evaluation of integrated, high-resolution models at continental-scales, especially the value of these simulations to policy and social issues. When she’s not thinking about water, Danielle enjoys snowboarding, exploring the mountains, and philosophizing about Harry Potter.


Nowfel Mahmud
Tennessee Department of Environment and Conservation

Nowfel Mahmud is an Environmental Consultant for the Tennessee Department of Environment and Conservation. He received his Ph.D. and MS from Tennessee Tech University and a Bachelor’s degree from the Bangladesh University of Engineering in Technology. His field of interest is riverine flood modeling, river morphology, and terrain data. Apart from spending time with GIS, DEMs, Satellite Images, and 1D/2D flood modeling he enjoys reading history and watching documentaries.


Brian Redder
Penn State University

I am currently a PhD candidate in Soil Science and Biogeochemistry and Penn State University where my work revolves around water quality and the preservation of our nation’s waterways. By combining elements of math, chemistry, geology, and biology, I work to understand sources of pollution to rivers and streams and calculate how much of a certain pollutant will end up in lakes, oceans, and estuaries. My work so far has focused on the Chesapeake Bay Watershed, specifically the area surrounding the Susquehanna River. However, poor water quality is a problem in every corner of the country, and my research aims to identify and reduce the amount of pollutants making their way into oceans and harming aquatic ecosystems.


Katarena Matos
Federal University of Espírito Santo

Katarena holds a Bachelor’s (2016) and Master’s (2018) degree in Hydrology from the University of Arizona, where her work focused on the hydrologic characterization of the Landscape Evolution Observatory at Biosphere 2. She currently works at the Institute for Climate Studies (IEC) at the Federal University of Espírito Santo (UFES) in Brazil, where she is leading a team to build an environmental database and web platform for the state of Espírito Santo.  Her current interests revolve around understanding how climate change will affect hydrologic extremes in urban regions. Katarena also enjoys collaborating on projects that bring awareness and solutions to the lack of diversity in the geosciences and likes to find ways of making science more accessible to everyone. During her free time, you will probably find her baking something she’s craving, trying to grow a green thumb, or relaxing at the beach.
