feliamini@usf.edu

Biography

I am a Ph.D. student in Geography and Environmental Science and Policy with an academic and professional background in GIS, remote sensing, land cover change, energy transition, and environmental management and policy. My research focuses on the intersection of geospatial technologies, energy transition, and forest conservation, with an emphasis on forest carbon stocks, land cover dynamics, and REDD+ monitoring. I hold an M.A. in Geography from Ohio University and an M.Sc. in Geographical Information Systems (GIS) from the University of Dar es Salaam, Tanzania. My master's research at Ohio University assessed the impact of land cover change on community access to fuelwood and the prospects for a just rural energy transition in Tanzania's Eastern Arc Mountains. This study integrated remote sensing analysis of Landsat satellite imagery with household surveys to examine deforestation trends and their implications for sustainable energy access. Beyond energy transitions, I have conducted research on participatory GIS (PGIS) for urban solid waste management, demonstrating how spatial data can enhance community-driven environmental planning. My current doctoral research builds on these themes, focusing on Assessing the Impact of Energy Transition on Forest Carbon Stocks Using Remote Sensing and GIS-Based REDD+ Monitoring. This interdisciplinary study explores energy transition's spatial and temporal effects on forest carbon stocks, utilizing remote sensing, GIS, and REDD+ monitoring frameworks to analyze forest conservation and climate mitigation strategies. Through my research, I aim to advance evidence-based environmental policy and sustainable resource management, particularly in tropical regions vulnerable to deforestation and climate change. By leveraging geospatial technologies and policy insights, my work seeks to contribute to a deeper understanding of how energy transition impacts forest ecosystems and carbon dynamics.

He is also a researcher at the Tanzania Forestry Research Institute (TAFORI)

Biography

My name is Juan Carlos Pena Philippides, I am a Doctoral Candidate in the School of Geosciences at the Â鶹ÊÓƵ in Tampa, I bring a robust academic background to the table. My journey began with a bachelor's degree in Biology and a minor in Chemistry from the University of New Mexico, where I graduated Suma Cum Laude. I then honed my expertise with a Master's in Water Resources, specializing in Hydroscience and the implications of water quality on human health.
Between my undergraduate and master's degrees, I devoted 21 years to biomedical research in lung immunology, with a specific focus on the effects of nicotine and cigarette smoke, both primary and secondary exposure. Later, I ventured into neurosurgical research, investigating the inhibition of mir 155 to promote recovery post-stroke in murine models. This extensive research journey ignited my interest in water issues and their potential impact on human health. I was fortunate to have Dr. Floyd Frost as a colleague and later as my mentor, whose work on cryptosporidiosis and giardiasis significantly influenced my research direction.
My doctoral research is not just the culmination of my academic journey, but a testament to my unwavering commitment to addressing pressing global issues. Water-related issues have always been a personal passion, and I am deeply grateful for the support and guidance of Professor Alsharif, whose insights have deepened my understanding of the current global water crisis.
My research interests are not just a professional pursuit, but a personal passion deeply rooted in the crucial study of our current global context. I am particularly fascinated by how megacities can promote IWRM and water governance to mitigate human disparities. My focus on water governance, integrated water resources management, water justice, and water diplomacy at the international level is driven by a profound understanding of how water quality and quantity can impact human populations, potentially leading to a state of hydro vulnerability. This topic is of utmost importance, and I am unwaveringly committed to contributing to its understanding and resolution.
