Early life and education

Qian is from China. She completed her bachelor's degree in biomedical engineering at Southeast University in Nanjing. [1] Qian moved to Shanghai for her doctoral research, where she worked at Shanghai Jiao Tong University on biochemistry. [2] She then moved to the California Institute of Technology as a postdoctoral fellow. [3] At Caltech, she worked alongside Erik Winfree on biochemical circuits. She used a reversible strand displacement process to create a simple DNA-based building block for a biochemical logic circuit. [4]

Research and career

Qian joined the faculty at Caltech in 2013. She was promoted to professor in 2019. [5] Her research considers molecular robotics and the self-assembly of nanostructures from DNA. These molecular robots can explore biologically relevant surfaces at the nanoscale, picking up molecules and transporting them to specific locations. [6] In 2011, she created the world's largest DNA circuit, which included over seventy DNA molecules. [7]

Qian has also created complex DNA origami. [8] She created two-dimensional images from DNA origami tiles. [8] She used DNA to create an artificial neural network. [9] The network consisted of a DNA gate architecture that can be scaled up into multi-layer circuits. [9] [10]
