Dr. Kostas Alexandridis,


Director, GeoCAS Institute

Kostas Alexandridis

Dr. Alexandridis serves as the Director of the Institute for Geocomputational Analysis and Statistics (GeoCAS). He holds a joint appointment between the Center for Marine and Environmental Studies (CMES) and the Department of Computer and Computational Sciences of the College of Science and Mathematics at UVI. He has a Ph.D. in Natural Resource Policy from Purdue University, and a BSc and MSc in Agricultural Economics and Rural Sociology from Aristotle University in Greece. Prior to joining UVI in 2010, he served as a Research Scientist with CSIRO, a leading international organization of the Commonwealth of Australia. His research focuses on the study and understanding of the complex relationships between our societies and our natural environment. His research expertise include social-ecological systems science, network sciences, spatial and geocomputational analysis, planning and decision making, cognitive, social and behavioral dimensions of environmental change, and complex adaptive systems science.

His teaching at both the graduate and undergraduate level at the University of the Virgin Islands includes human dimensions in natural resource management and policy, mathematical modeling, geographic information sciences, and scientific computing applications.

Dr. Alexandridis has a growing record of international publications, and serves in the editorial board for the Elsevier's Environmental Management and Software Journal, and has served as a scholarly peer reviewer in a number of academic journals. He is a certified GIS professional (GISP) and a member of a number of professional and scholar organizations, including the Association of American Geographers (AAG), the US Charter of the International Association of Landscape Ecologists (US-IALE), the International Society for Bayesian Analysis (ISBA), and the American Association for Advancement of Science (AAAS).

Melissa Kimble,


Spatial Analyst, GeoCAS Institute

Melissa Kimble

Melissa Kimble is currently a Spatial Analyst at the GeoCAS Institute and the Center for Marine and Environmental Studies(CMES). She attended the University of Alaska, Anchorage (UAA) and Humboldt State University (HSU) for her undergraduate and graduate degrees. She has a B.A. in Anthropology and a B.S. in Environmental Science with the Geospatial Sciences option from HSU.

Her Masters in Natural Resources: Environmental and Natural Resource Sciences (HSU) lead to working on web mapping and database applications, remote sensing related projects, and general work as a GIS analyst and consultant. She was also involved in developing course materials and labs for an introductory lab in GIS, and taught this lab at HSU as a teaching associate. The primary objectives of her thesis were to show the impact of varying modeling extent and incorporating multiple sources of error in habitat suitability models (HSMs) with the novel modeling package, Hyper-Envelope Modeling Interface, Version 2 (HEMI 2). The work described above required competence in multiple programming languages such as, but not limited to: JavaScript, Python, PHP, R, SQL, SQL*Plus, and PL/SQL.

Stevie Henry,


GIS Analyst, ECC

Stevie Henry

Stevie Henry holds a Bachelor of Arts in Social Sciences from the University of the Virgin Islands (UVI). He also holds Master in Community and Regional Planning is from the University of New Mexico as a Housing and Urban Development (HUD) Fellow. He has been (2006) the representative of the Virgin Islands at the National States Geographic Information Council (NSGIC) and a founding member of the Virgin Islands Geospatial Information Council (VIGIC). He has conducted workshops as a GIS/GPS instructor for professionals in the Virgin Islands and other U.S. outlaying areas. Stevie directed the development of the UVI GIS curriculum for undergraduates and serves as the lead instructor for the Introduction to GIS course.

Stevie came to the UVI from the Virgin Islands Department of Planning and Natural Resources Division of Comprehensive and Coastal Zone Planning where he designed and built zoning and land use databases for studying the economic and environmental impact of development on the human, historical and environmental resources of the Virgin Islands.
     Stevie has led the mapping of several major projects for the Virgin Islands: Vegetation and Marine Communities of the Virgin Islands; Adoption of Census Tract Maps for the Virgin Islands 2000 Census; Propose Virgin Islands Comprehensive Land and Water Use Plan District Map.

Besides mapping Stevie has been an advocate for State-wide (Territory) GIS coordination. He was co-principal investigator for Virgin Islands Geospatial Infrastructure strategic plan funded by Federal Geographic Data Committee (FGDC) Fifty States Initiative Cooperative Agreement Program. Stevie coordinated with the U.S. Army Corp and U.S. Geological Service the acquisition of aerial photos for Puerto Rico and the Virgin Islands (2004, 2007 and 2010).

Fields of interest include: natural resources, land use, public health, energy conservation, economics, sustainable development emergency response, and history. Major topic of interest organizational adoption and application of geospatial technology which includes analyzing work flows, GIS/GPS education, project management, meta data, data distribution and data maintenance. Stevie has been involved in the development of local GIS/GPS learning activities for introducing non-GIS users as well as novice users to use of geospatial technology.

Dr. Simon Pittman,


Affiliated Faculty, Spatial and Marine Coastal Planning

Simon Pittman

Dr Simon Pittman is a marine spatial ecologist with a Ph.D. in Geographical Sciences from the University of Queensland, Australia and a M.Sc. in Environmental Sciences from the University of Wolverhampton in England. Simon's primary area of research is the emerging field of Seascape Ecology; the application of landscape ecology concepts and tools to the marine environment. For the past decade, he has worked as a Research Scientist at NOAA's Biogeography Branch applying spatial technologies and predictive mapping to support marine spatial planning. During that time he spent three years at the University of the Virgin Islands as Science Coordinator for NOAA's Coral Reef Conservation Program.

At UVI, he coordinated a graduate module on GIS and Spatial Modeling and began working on the early foundations of what is now UVI's Institute for Geocomputational Analysis and Statistics. Recently, he has focused on spatial predictive modeling using machine learning algorithms and GIS to map marine species distributions and responses to environmental change. In general, he focuses on providing ecological information and spatial decision tools to assist ecosystem management and risk assessment. He serves on NOAA's Caribbean Steering Committee and the Virgin Islands Reef Resilience Working Group and is Editor-in-Chief for the NOAA in the Caribbean Newsletter.

Now located at the Marine Institute, Plymouth University, UK, Simon is Director of Seascape Analytics Ltd, a spatial science consultancy, Research Fellow in the Centre for Marine & Coastal Policy Research at Plymouth and Affiliate Faculty at Oregon State University.

Deborah Elizabeth Smith,

Graduate Student, Masters in Marine and Environmental Studies.

Research Assistant, GeoCAS Institute

Deborah Elizabeth Smith

D. Elizabeth Smith is currently a first year student in the Master of Marine and Environmental Sciences program at the University of the Virgin Islands (UVI). She is a Virginia native and attended Old Dominion University (ODU) for her Bachelor of Science degree in biology, with a concentration in marine science. During her undergraduate career, Elizabeth worked for the Virginia Aquarium and held many executive positions in ODU’s Marine Biology Student Association. In addition to classes, she is currently involved in a grant to reduce marine debris in the USVI through a partnership with the 6th and 7thgrade classes of Calvary Christian Academy. In her free time, Elizabeth enjoys playing guitar and SCUBA diving on the many lovely reefs in the USVI.

As part of her research assistantship work, Elizabeth is developing and implementing a study to measure the attitudes and beliefs of visitors and residents towards sustainability in the Brewers Bay area of St. Thomas. The relationships between participants’ demographics (e.g., current residence, education, employment, etc.) and attitudes towards environmental conservation and ecotourism will be identified. Surveys will be administered in the Brewers Bay area during the summer (2017) and analyses will determine patterns of beliefs. The results from this study could assist in future management considerations in developed island communities.
