Saurav Shrestha
PhD Student
I am Saurav Shrestha. I completed my Bachelor’s(2015) and Master’s degree (2020) in Geotechnical Engineering from Institute of Engineering, Tribhuvan University, Nepal. I completed my first two years of Ph.D. in Virginia Tech and I am continuing it as a third year student at the University of Florida in the Geosystems Department. I am working in a research project to perform probabilistic analysis of environmental effects on sensors placed close to the seabed and it’s effects on the sensor network performance. The environmental effects include lateral displacement due to hydrodynamic actions, embedment of sensors due to self weight and impact, scour burial, liquefaction effects, etc. I try to explore the complex interactions between the coastal environment and sensor, trying to enhance our understanding of how hydrodynamic and geotechnical factors influence sensor burials and subsequent performance.
Stephen Adusei
PhD Student
Stephen Adusei is pursuing a Ph.D. in Geotechnical Engineering at the University of Florida. His research interest is at the intersection of Geospatial Technology and Geotechnical Engineering. He is currently working on identifying coastal features from satellite imagery and assessing how they impact trafficability. Stephen is from Nkawkaw in the Eastern part of Ghana and earned his BSc in Geomatic Engineering from the University of Mines and Technology (UMaT) in 2021.
Fred Falcone
PhD Student at Virginia Tech
Freddie is a PhD student at Virginia Tech, working on trafficability of mud and mixed sediment flats using satellite-based remote sensing. Freddie received his BS degree in Civil Engineering from Wentworth Institute of Technology in Boston, Massachusetts in 2014, and his MS degree in Geotechnical Engineering from Virginia Tech in 2015. After graduating with his MS degree, Freddie spent 6 years working as a geotechnical engineer for Mueser Rutledge Consulting Engineers in Washington, DC. He worked on a variety of field and office projects ranging from geotechnical investigations to deep foundation design and inspection. Outside of engineering, Freddie enjoys hiking and traveling with his wife and two dogs.
Md Rejwanur Rahman
PhD Student at Virgina Tech
Md Rejwanur “Rahi” Rahman is a Ph.D. student at Virginia Tech, specializing in Probabilistic Sediment Behavior Classification through Geotechnical and Geophysical methods. Originally from a small town of Bangladesh, he earned his BS degree from Bangladesh University of Engineering and Technology in 2019 and went on to complete his MS at the University of Kansas in 2020. Beyond academia, he enjoys activities such as driving, watching documentaries, sports, sitcoms, and crime movies. With a passion for blending geotechnical expertise and machine learning techniques, Rahi is dedicated to make significant contributions to the realm of Marine Geotechnics.
Jonathan Moore
MS student at Virginia Tech
I’m a Master’s student studying coastal and marine geotechnics. My research focus is the overlap of computational modelling and field work.
I want to better understand sediment-fluid interaction in coastal and riverine environments, so that the impacts of climate change and the evolution of coastlines can be better understood and modelled. Currently, I’m modelling the impact of a Free Fall Penetrometer (FFP) into non-cohesive sediment using a strain rate dependent constitutive model. In the future, I want to work on understanding fluid-cohesive sediment interaction through field, lab, and numerical analysis.Noah Evans

Staff
Charli Pezoldt
Research Coordinator
Studying coasts has been a consistent passion in Charli’s life for as long as she can remember. Charli grew up in Miami, FL, snorkeling over the seagrass beds, walking the beaches, skateboarding around the sea walls, swimming on the reefs, and noticing the subtle changes that would happen over the years. She would take notes about her observations, try to understand why things were changing, and was filled with a desire to make a positive impact in the coastal systems that she grew up loving! Charli worked in the Wetland Ecosystems Research Lab at FIU prior to joining the Center for Coastal Solutions at UF in 2022, where she now works as a Research Coordinator for Dr. Nina Stark in Coastal and Marine Geotechnics. She has worked on a variety of research projects in Coastal Engineering and Ecology, and one of her favorite things about work is the ability to learn something new every day; continually growing her interests and skills!
In her free time, you can find Charli all around town. When she is not curled up reading a good book, she loves to go diving, play guitar, and dance! Gainesville has an amazing local music scene, and Charli is always happy to go to a show!
Sharlynn Sweeney
Research Coordinator
Sharlynn received a dual BS in Marine Science & Biology from the University of Miami, had a brief stint as a zookeeper, then moved to Gainesville and worked as a biological scientist in a neuropharmacology lab at UF. She returned to school with a much-expanded scale of interest and earned her PhD in Environmental Engineering Sciences at UF in 2009 with a focus on Systems Ecology and a concentration in GIS. She worked at the UF Howard T. Odum Center for Wetlands for 12 years as a Program Coordinator, then Communications Specialist, and has been with the UF Center for Coastal Solutions (CCS) for 4 years as a Research Coordinator, serving as project manager for several large multi-discplinary projects, and providing support for various activities and projects associated with CCS. Sharlynn loves libraries, gardening, maps, travel, sci-fi, and viewing the world through a systems ecology lens.
