Biography

Professor Madhavan received her bachelor's degree in metallurgical engineering in 1991 from the Indian Institute of Technology, Chennai, and a master of technology degree in solid state materials in 1993 from the Indian Institute of Technology, New Delhi. She obtained her phD from Boston University in 2000. She held a postdoctoral appointment at the University of California, Berkeley from 1999 to 2002, before joining the physics faculty at Boston College in 2002. She joined the faculty at Illinois in 2014 as a full professor.

Research Statement

Professor Madhavan investigates fundamental problems in quantum materials where interactions between the spin, charge, and structural degrees of freedom lead to emergent phenomena. She uses the tools of scanning tunneling microscopy (STM), scanning tunneling spectroscopy (STS), spin-polarized STM (SP-STM) and molecular beam epitaxy (MBE) to unravel the mysteries of complex systems at the atomic scale. Her group carries out challenging, high-risk experiments, wherein the possibility of discovering new phenomena is high. Her team's recent work has focused on STM studies of complex oxides and monolayer films of topological materials and transition metal dichalcogenides.
