Research

My research area is Algebraic Geometry. My research interests include Bridgeland stability conditions, moduli space, derived category, birational geometry, counting invariants and wall-crossing.

• Bridgeland stability condition – new aspects to symmetry and classification
• Bridgelands stabilitetsvillkor – nya aspekter av symmetri och klassificering
