Paloma Carton de Grammont, Research Coordinator III

Pronouns: She/Her/Hers
Phone: (352) 294-7744

Paloma holds a Bachelor’s degree in Biology, a Master’s degree in Environmental Sciences and a Doctor’s degree in Geography, all earned at Universidad Nacional Autónoma de México. She is also a UF Natural Resources Leadership Institute (NRLI) program alumnus.

For over fifteen years she has coordinated interdisciplinary, multi-institutional, and international teams conducting research and developing policies in diverse topics of natural resource management and environmental change. Her professional experience spans academia, the public sector, and non-governmental organizations, both in the US and Mexico.

Paloma applies her interdisciplinary training, professional experience and facilitation skills to support the Water Institute research, extension, outreach and education programs. Her experience working in Latin America and fluency in Spanish and French equip her well to further the Institute’s mission in an international context.

Karen Schlatter, Research Coordinator III

Pronouns: She/Her/Hers
Phone: (352) 294-7742

Karen earned a Bachelor of Science degree in Biology from McGill University (Canada) and a Master of Science Degree in Environmental Studies from the University of Colorado Boulder. She is a UF Natural Resources Leadership Institute (NRLI) Class XVIII alumnus and winner of the class Burl Long award.

Prior to joining the Water Institute, she worked for nine years on binational water resource management and ecological restoration of the Colorado River in Mexico. She has facilitated multi-stakeholder partnerships with U.S. and Mexican government agencies, universities, non-governmental organizations, and community groups to achieve conservation goals and inform water policy through collaborative science.

Karen was an agricultural extension volunteer in the Peace Corps in Paraguay and is fluent in Spanish and Guarani. She applies her diverse background in resource management, interdisciplinary partnerships, and stakeholder facilitation to coordinate the Institute’s water-related research, extension, and education initiatives.

Rob de Rooij, Research Assistant Scientist

Pronouns: He/Him/His
Phone: (352) 294-7745

Rob earned his Doctor of Science degree at the Centre of Hydrogeology, University of Neuchatel (Switzerland) in 2007. His research activities were developing a finite element code for coupled, variably saturated flows, solving problems related to non-linearity, numerical instability and flow coupling, validation and verification.

His research at the Water Institute includes the development of a particle-tracking scheme tailored for coupled surface-subsurface flows as well as a finite difference scheme for coupling conduit flow, subsurface matrix flow and surface flow in karst systems. The objective of these schemes is to gain further insights into complex natural flow systems.

At this moment his research is focused on developing and testing methods to generate random 2-D and 3-D conduit networks for incorporation into watershed scale flow and transport models, and develop and test coupled discrete-continuum flow and transport models for the Silver Springs basin in Florida.


Pronouns: He/Him/His
Phone: (740)-438-6453

Nathan holds a B.S. and M.S. degree in Bioengineering from the University of Toledo. He earned his Ph.D. and M.E. in Environmental Engineering Sciences from the University of Florida in 2018. His dissertation, “Linking Landscape Hydrologic Processes to Spring Ecosystem Dynamics”, investigated potential drivers of change in the primary producer communities of Florida’s spring-fed rivers using a multi-scale modeling approach. 

Some of his broad research interests include: the intersection of water, energy, food, and the environment; complex system dynamics; ecosystem dynamics and restoration; and the nature of how scientific inferences are obtained from data. He has experience in theoretical, applied, and experimental science in several disciplines, ranging from the development and implementation of mathematical models to the design and execution of field and laboratory experiments.

Nathan applies his multi-disciplinary experience to his research at the Water Institute, which focuses on understanding hydrological, ecological, and social dynamics in karst watersheds.

Christian A. Rodriguez, Program Assistant

Pronouns: He/Him/His
Phone: (352)-294-7743

Christian holds an Associate’s degree in Mathematics from Santa Fe College where he graduated as a James Gregg Honors Scholar. He will be finishing his Bachelor’s degree in Philosophy from the University of Florida in Fall 2022. He also hopes to pursue a Master’s degree at UF.

Christian’s career has been centered around supporting the research UF’s faculty and students partake in. He previously worked at the UF Survey Research Center as a Programming supervisor where he collaborated with clients and researchers to review and program their surveys. He then worked for the UF Center for Undergraduate Research as an Administrative Specialist I where he assisted with varied undergraduate research programs and scholarships that the center offered.

As the Program Assistant for the Water Institute he will provide communications, programmatic and administrative assistance to our programs.
