Postdoctoral Fellows

Anju Toor

email: atoor@berkeley.edu
Anju Toor completed her Ph.D. in Mechanical Engineering at University of California, Berkeley in 2017 under the guidance of Prof. Albert Pisano. She also collaborated closely with Prof. Thomas Russell and Brett Helms at LBNL. During Ph.D. she worked on (1) design and synthesis methods for functional, responsive nanocomposites with tunable mechanical properties at liquid interfaces and (2) dielectric property enhancement in polymer nanocomposite materials for energy storage applications. After graduation, she worked at Intel as a Process Integration Technologist in the 3D XPoint Non-volatile Memory Development. She joined Arias’s group in Mar 2019, will be working on “On-Chip Integrated Microbatteries” for powering MEMS portable devices.
