[1] She earned her PhD at Graduate Center of the City University of New York in 2011, working with Teresa Bandosz.
[5] Petit completed postdoctoral research in Alissa Park's group at Columbia University.
[4] She developed several characterisation techniques to analyse their suitability for carbon capture, including nuclear magnetic resonance, Attenuated total reflectance Fourier-transform infrared spectroscopy and differential scanning calorimetry.
[9][10][11] Petit is Associate Editor of the journal Frontiers in Energy - Carbon Capture, Storage, and Utilization.
In 2019 she was awarded a prestigious European Research Council grant to develop a new class of photocatalysts to help convert carbon dioxide into fuel using sunlight.
