Ru Zhang, Principal Investigator

Position:
Assistant Member, Donald Danforth Plant Science Center,  since September 2016

Education and trainings:
Postdoc, Department of Plant Biology, Carnegie Institution for Science, 2010-2016
University of Wisconsin-Madison, PhD, 2009
Nankai University, China, BS, 2005

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.

Ningning Zhang

Position: 

Postdoctoral Associate, since May 2017

Education:

Ph.D. Molecular Biosciences, Arkansas State University
M.S. Biotechnology, Arkansas State University
B.S. Bioengineering, Qindao Agicultural University

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.

She revealed several interesting chemicals and molecular mechanisms that enhance the tolerance of plant under high-salinity stress responses. In Zhang Lab, she will involve in a project that apply a novel combination of in silico and experimental approaches to predict and validate the structure and function of poorly-characterized and unannotated proteins in Arabidopsis thaliana, Setaria viridis and Chlamydomonas reinhardtii. In the free time, she likes playing with her children, cooking and exploring nearby.

Erin Mattoon

Position: 

Graduate Student, since April 2018

Celine Xia

Position: 
Lab Technician, since January 2020

Education:
M.S. Auburn University, Dec 2019
B.S. Huazhong Agricultural University, July 2017

About: Celine received her master’s degree in from Auburn University in 2019. Her research was improving Romaine lettuce growth in the greenhouse hydroponic systems. With high temperature and humidity in summer time, lettuce grew too fast in the greenhouse hydroponics systems, which caused calcium ion deficiency in the young growing tips. Physiological disorders like tipburn and bolting happened and damaged the lettuce marketable value. To mitigate tipburn and bolting, Celine increased the horizontal air flow speed in the DWC system and decreased root-zone solution temperature in NFT system to slow down growth rate to help calcium efficiently translocated to young leaves. At Zhang’s lab, Celine will work as a lab technician to start a hydroponics system in the greenhouse of Danforth plant science center. Celine likes travel, sports and music.
