Roy Armstrong, PhD


Dr. Roy Armstrong has a bachelor’s degree in biology from Boston University and a master’s and a doctorate in Marine Sciences from the University of Puerto Rico at Mayagüez (UPRM). As a graduate student in the Department of Marine Sciences he pioneered the use of remote sensing technology for studies of the marine environment in Puerto Rico. After finishing his Ph.D. in 1990, he spent four years at NASA’s Ames Research Center as a National Research Council post-doctoral fellow and a Research Associate working with hyperspectral remote sensing. Upon his return to Puerto Rico, with funding from NASA and NOAA, he established the Bi-optical Oceanography laboratory at UPRM ( His research is highly interdisciplinary, being mainly concerned with water optics, airborne and satellite remote sensing, coral reef ecology and bio-optics, and the effects of Sahara dust aerosols in the eastern Caribbean.
