Leena Aggarwal is a postdoctoral research associate at Brookhaven National Laboratory, Upton, New York, USA. Previously, she was a postdoctoral fellow at the University of Ottawa, Canada (2021-2023), where she worked on the fabrication and study of transition metal dichalcogenides (TMDs) related devices using scanning tunneling microscopy. From 2018 to 2021, she was a postdoctoral fellow at the University of Illinois, focusing on the synthesis and characterization of thin films of topological materials. Before that, she worked as a research fellow at the University of Pittsburgh (2017-2018), studying the electronic properties of LAO/STO heterostructures at ultra-low temperatures and high magnetic fields. Leena received her Ph.D. from the Indian Institute of Science Education and Research (IISER), India in 2017. Her research interests include scanning probe microscopy, molecular beam epitaxy, and low-temperature physics.
