Cassandra R. Hunt Curriculum Vitae Last updated: October 2016 University Email (preferred): crhunt-at-berkeley.edu Permanent Email: hunt-at-alum.mit.edu Telephone: (510) 486-6194 Website: CassandraHunt.com Materials Sciences Division Lawrence Berkeley National Laboratory 1 Cyclotron Road, M/S 2-202 Berkeley, CA 94720 Research Statement My long-term research aims are to explore and understand phase competition, emergent order, and non-equilibrium states in correlated and other novel materials, and to develop 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.
