Mallika Randeria, Pappalardo Fellow
Area of Physics
Mallika Randeria is excited by questions of how strong interactions give rise to new and unexpected quantum behavior in materials. Her PhD research has centered on imaging spontaneous symmetry breaking and investigating one-dimensional behavior at electronic domain boundaries in the quantum Hall regime. These experiments were performed using a scanning tunneling microscope, a unique instrument with atomic scale resolution, which provides local, microscopic information of sample surfaces. At MIT, Randeria is interested in exploring these ideas of emergent quantum phenomena in two-dimensional materials using complementary global measurement techniques including electronic transport.
Randeria is also passionate about increasing the diversity in STEM fields by creating an empowering environment at both an institutional and individual level. She enjoys sharing her joy of science with the public and teaching nontraditional students.
Mallika Randeria spent a large part of her childhood in Mumbai, India, interspersed with periods in the USA, before moving to Ohio, where she attended high school. Randeria received her undergraduate degree in physics from MIT and she completed her PhD in experimental condensed matter physics from Princeton University, working with Prof. Ali Yazdani.
