• Application of geochemical data from volcanic, metamorphic and mantle rocks to understanding:
  (1) generation of magma at subduction zone and mid-ocean ridges
  (2) melt/fluid transport in and interaction with the upper mantle
  (3) crustal recycling and its influence on the mantle heterogeneity
  
• Trace element partitioning between mantle minerals and melt/fluid
  
• Analyses of isotopic ratios and major and trace element abundances in volcanic rocks and mantle peridotite
  
• Development of analytical technique using SIMS and ICP-MS for trace elements including LILE, REE and HFSE
  
• Dynamic and static compression experiments on geological materials to investigate structure and phase transformation in planetary interior
