About Me

I am a Senior Research Scientist at the Interdisciplinary Theoretical and Mathematical Sciences Program (iTHEMS), RIKEN. My research explores the frontiers of quantum phases of matter, including topological superconductors, Majorana fermions, and novel quantum computational platforms like twisted bilayer graphene.

Research Interests

• Topological Superconductors and Insulators
• Majorana Fermions and Quantum Computation
• Twisted Bilayer Graphene
• Emergent Topological Phases in Condensed Matter
