About: Ru's research experience centers on photosynthesis and range from plant physiology/biochemistry to algal genomics to organelle evolution. During her PhD training at the University of Wisconsin-Madison, she worked with Dr. Thomas Sharkey using gas exchange and spectroscopic methods to study the effects of high temperature on photosynthesis in leaves of Arabidopsis and tobacco plants. During her postdoctoral training with Dr. Martin Jonikas and Dr. Arthur Grossman at the Carnegie Institution for Science, Ru continued to explore photosynthesis by developing high-throughput genotyping and quantitative phenotyping tools for the eukaryotic, unicellular green alga Chlamydomonas reinhardtii to identify photosynthesis-deficient algal mutants on a genome-wide scale. She also participated in the generation of a genome-saturating, indexed, mutant library of Chlamydomonas. The library could be used as both forward and reverse genetic platforms to dissect cellular processes under various conditions. In addition, she has worked on the photo-acclimation of the green amoeba Paulinella chromatophora (which has nascent “plastids” that evolved much more recently, 0.06 billion years ago) to gain insight into the evolution of photosynthetic organelles. She is passionate about how photosynthesis in plants/algae respond to abiotic stresses, especially heat stress. Her long-term career goal is to engineer photosynthesis for improved agricultural and biofuel production. Outside of the lab, Ru enjoys playing with her kids, cooking, swimming, and watching movies.
Postdoctoral Associate, since May 2017

About: Ningning received her PhD in Molecular Biosciences in May of 2017 by dissecting the O-glycosylation process of plant cell wall structural glycoproteins and reengineering the plant cell wall for improved biomass processability. She started in the Zhang Lab as a postdoctoral research associate in the same month to study how photosynthetic organisms respond to their environment by using cutting-edge technologies. Specifically, Ningning is using the unicellular green alga, Chlamydomonas reinhardtii, as a model system to better understand how photosynthetic cells sense and respond to high temperatures. A genome-saturating, indexed, algal mutant library and a quantitative phenotyping tool are used to conduct high-throughput genetic screening for mutants with interesting phenotypes. In her free time Ningning likes to work with plants, especially cacti. She also likes staying active by running frequently and playing pingpong.
Postdoctoral Associate, since October 2018
Ph.D. Biological Engineering, Northwestern University (expected June, 2018)
B.S Cell and Molecular Biology, Ohio University in Athens
Her graduate work focuses on engineering the properties of the prototypical MAP Kinase pathway in yeast for use in biosensor diagnostics. In the Zhang lab, Sarah will use the grass Setaria viridis
as a model organism for photosynthesis in C4 plants such as maize and sorghum. She will combine traditional genetic approaches with engineering techniques to improve the thermostability of C4 photosynthesis, making C4 plants more tolerant of high temperature stresses. In her free time, Sarah enjoys cooking, running, opera and knitting.
