Samantha Grist

Dr. Samantha Grist completed her PhD work in 2016, under the supervision of Prof. Lukas Chrostowski. She is now a postdoctoral fellow at the University of California Berkeley.

Samantha is passionate about learning, solving problems, and working on interdisciplinary research. Her research focuses on using microfluidics to recreate the microenvironment of cells within tumours during in vitro experiments such as drug screening. Specifically, she uses 3-D cell culture and on-chip oxygen control to recreate chronic and time-varying low oxygen levels that can exist in tumours and influence cell behaviour and drug response. Samantha has also integrated optical oxygen sensors, measured using fluorescence microscopy, into these environments as well as worked on novel imaging protocols to improve data analysis from 3-D cell cultures. In addition to her thesis work, Samantha has designed and tested optical biosensors using silicon nanophotonics technology combined with microfluidics.
