Marco Millones Mayer
Assistant Professor
B.A., Catholic University of Peru-PUCP;  M.A., University of Miami; Ph.D., Clark University
mmillone@umw.edu; Monroe 113B.
Millones teaches GIS, spatial analysis and remote sensing at graduate and undergraduate levels. His work focuses on applications of geospatial analysis for the study of human-induced landscape change, spatial accuracy, spatio-temporal modeling, and public policy. Examples of these applications include: map accuracy  measures, geospatial impact evaluation of land tenure programs, locational error and its impact on spatial modeling; using food flow data to measure regional sustainability; and, exploiting remotely sensed time-series to describe environmental trends and abrupt changeCurrent CV (PDF Format)

Brian R. Rizzo
Associate Professor
B.A., M.A. University of Western Ontario; Ph.D. University of Virginia.
rizzo@umw.edu; Monroe 321.
While an undergraduate geography major – decades ago, Brian became involved with a new area of geography that would evolve into Geographic Information Systems (GIS). In the 20+ years since, he has been involved in developing GIS data structures and applications to address a wide range of issues. Brian’s research focus’s on global climate change as it relates to the biogeographic distribution of vegetation and Infrastructure management within a GIS framework. Current CV (PDF format)

Ping Yin
Associate Professor
B.E., Tsinghua University; M.E. Tsinghua University; Ph.D., University of Georgia
pyin@umw.edu; Monroe 113C.
Ping Yin specializes in Geographic Information Science as applied to health geographies, web-mapping, and spatio-  temporal modeling.  He teaches both undergraduate courses in GIS and several courses in the Masters of Science in Geospatial Analysis    (MSGA) program. Current CV (PDF Format)

Adjunct Faculty

Scott Allen
B.A., Mary Washington College; M.A., State University of New York-Stony Brooks; Ph.D., George Mason University
C. Scott Allen is a remote sensing scientist at Zeta Associates. Over the last two decades, he has worked in GIS, GPS, and remote sensing across a wide swath of the geospatial community including federal government, commercial remote sensing, and the telecommunications industry. In addition to longstanding interests in environmental applications of remote sensing, he is currently investigating the use of imaging spectroscopy for personnel search and rescue. He teaches the undergraduate and graduate sections of remote sensing.


Benoit Parmentier
Licenciate (B.S.), DES (M.S.), Université Libre de Bruxelles, Belgium; M.A., Ph.D., Clark University
Benoit Parmentier is a geographer and data scientist at SESYNC (University of Maryland) broadly interested in landscape change and global environmental change. His research uses geospatial datasets, Remote Sensing imagery and time series to track fire and land cover change, study landscape changes in urban-rural transition areas, produce environmental and climate datasets, study climate teleconnections and examine food trade flows for sustainability studies.

Justin Roberson
B.A., University of Oklahoma; M.S., University of South Carolina
Justin is the GIS Coordinator for the Fairfax County Park Authority in Northern Virginia. He serves as the Park Authority’s geospatial technology expert and coordinates, develops and maintains all agency geospatial data, applications, tools and equipment to meet the agency’s mission and goals. Justin presently teaches the Introduction to GIS course and has previously taught Introduction to Physical Geography and Plant Taxonomy courses. His research in graduate school focused on landscape ecology and biogeography, with an emphasis on species distribution modeling and vegetation community ecology. In his free time, he enjoys hiking with his dog and relaxing on the couch with his cat.

Steven Schaffer, MS
