Dr Ana Santos
Green Economy Fellow
Division: ES Mineral and Planetary Sciences Division
Summary
My research interests lie on geomicrobiology and biogeochemistry focused on the mineral-microbe interactions as well as the development of bioprocesses for metal extraction from low-grade ores, mineral wastes and remediation of acid mine drainage.
