My interests
• “Wave-equation” imaging
– Migration velocity analysis (MVA)
• angle-gathers
• residual migration
• wave-equation MVA
– Amplitude variation with angle (AVA)
• angle-gathers
• amplitude-preserving migration

“Wave-equation” imaging
• more accurate physical model
• paraxial wave-equation vs. eikonal equation
– band-limited
– multi-pathing
• angle-domain CIGs
– MVA
– AVA
