Lavanya Raman

Research:

Lavanya’s research focusses mostly on high-temperature materials for structural application. Her doctoral work was on refractory high entropy alloys. The thesis deals with investigations on various synthesis routes, phase and microstructural stability, and their deformation mechanism at high temperature. Her postdoctoral research at Penn State was on alloy development for ultra-high temperature refractory materials and developing mechanically strong interface between carbon fiber and ceramic matrix. Her current research work at UW Madison focusses on the development of vertically aligned CNT and rolled homogeneous armour steel and understanding their synthesis, structure-property correlation.
