Research Experience
My research centers on exploring phase competition in correlated and other novel materials, and developing methods to manipulate and control these systems using ultrafast techniques. Light pulses tailored to selectively perturb lattice, electronic, or spin degrees of freedom can tip the balance between competing orders, clarifying the origin of the equilibrium ground state. Targeted excitation can also generate new states that cannot be accessed in equilibrium, offering an avenue of materials control on the femtosecond to picosecond timescale.
