Biography:

Suchitra Sebastian received a PhD in Applied Physics at Stanford University, USA in 2006, prior to which she completed an MBA at the Indian Institute of Management (Ahmedabad), India and a BSc in Physics at the Women's Christian College (Chennai), India. She was awarded the Lee Osheroff Richardson North American Science prize for her PhD work on frustrated quantum magnets. She then moved from the sunny shores of California to the somewhat grayer environs of the University of Cambridge as a Junior Research Fellow in Physics at Trinity College, and received a postdoctoral award from the Institute of Complex Adaptive Matter for research conducted at the National High Magnetic Field Laboratory (USA). From 2010, she is a Royal Society University Research Fellow in Physics at the Cavendish Laboratory, and a fellow of King's College. In 2012 she was awarded the Young Scientist Medal in magnetism by the International Union of Pure and Applied Physics, and the Moseley Medal by the Institute of Physics for her discoveries in frustrated quantum magnets, heavy fermion systems, and high temperature superconductors.

Research Interests:

Suchitra's research interests are in the area of correlated electron systems, particularly in novel materials. Her research focusses on the search for emergent quantum phenomena in a variety of new materials under extreme conditions. Toward this end, single crystals of materials such as rare earth magnets, iron pnictide and cuprate high temperature superconductors, and frustrated quantum magnets are synthesised in the laboratory, and low temperature thermodynamic and transport measurements performed under high applied pressures and large magnetic fields up to 100 T both in-house and in international facilities.
