معرفی
Shanaka de Silva is a Professor at Oregon State University's College of Earth, Ocean, and Atmospheric Sciences (CEOAS). His research focuses on volcanology, igneous petrology, and aeolian geomorphology, with fieldwork in the Andes, Indonesia, and Saudi Arabia. He teaches courses including Volcanology and Advanced Petrology. His work integrates field studies, geochemistry, and geophysics to understand volcanic processes and hazards.
Education
- B.Sc. (Hons) Geology, University of Southampton, 1982
- Ph.D. Earth Sciences, Open University, 1987
Research Interests
De Silva investigates explosive volcanism, caldera formation, and magmatic-tectonic interactions. Key themes include: (1) magmatism in volcanic arcs, (2) physical volcanology (pyroclastic currents, lahar sedimentology), (3) petrology of explosive eruptions, and (4) aeolian processes as planetary analogs. His work emphasizes volcanic hazard assessment and planetary surface evolution.
Collaborations & Outreach
He collaborates globally, including with Saudi Arabia's Harrat Khaybar and Indonesia's Toba Caldera. His outreach includes VolcanoWorld and programs promoting equity in Earth Sciences, such as Increasing Diversity in Earth Sciences.
Grants & Advising
- Advises ~20 current and former Ph.D./M.S. students
- Hosts visiting researchers from institutions like Monash University and NASA
- NSF and international grants fund projects on magma dynamics and planetary processes
Labs & Teams
His research group integrates fieldwork, lab analyses, and computational modeling. Key projects include the Toba Caldera resurgent dome study and aeolian bedform analysis in Argentinean gravel plains.
