Ms. Dorothy Sachdeva is a PhD candidate at the Materials Research Centre, Indian Institute of Science (IISc), Bengaluru. Her doctoral research focuses on the synthesis of two-dimensional nanomaterials with precise control over their composition and morphology. She performs in-depth characterization to understand the chemical and phase transformation mechanism using advanced electron microscopy techniques.
She holds a bachelor’s and master’s degree in chemistry from Delhi University and IISc, Bengaluru, respectively. She is a recipient of the Prime Minister Research Fellowship from the Government of India, which funds her research at IISc, Bengaluru. She has publications in peer-reviewed international journals with high reach and has presented papers at national and international conferences.
As a Fulbright-Nehru Doctoral Research Fellow, Dorothy is working with in situ electron microscopy and electron energy-loss spectroscopy. PtCu alloy nanoparticles nucleated on highly reduced SrTiO3 nanocubes deactivate for the preferential oxidation of CO to CO2 at higher temperatures. She is trying to identify the mechanism of deactivation under operando conditions, enabling her to visualize and analyze catalytic processes with high spatial and temporal resolution in real time. When not in the lab, she can be found reading, playing, and cooking. Dorothy loves spending time with her friends and family, and enjoys travelling and meeting people from various cultures.
