Principal Investigator

Wolfgang Busch

Associate Professor
Plant Molecular and Cellular Biology Laboratory
Integrative Biology Laboratory

Wolfgang did his undergraduate studies in Biology at the University of Tübingen, Germany. During this time, he also spent 8 months at UC San Diego where he received training on computational biology and conducted research on transporter proteins. During his PhD at the Max Planck Institute for Developmental Biology in Tübingen, he identified novel key regulatory genes and modules for plant stem cell control via a systems biology approach integrating transcriptome- and genome-scale transcription factor-DNA binding data. Wolfgang received his PhD in 2008 from the University of Tübingen. During his postdoctoral training at Duke University he contributed to the discovery of spatiotemporally defined regulatory modules that control proliferation of stem cells and differentiation in the root, and used high-throughput confocal microscopy to capture dynamic features of gene expression. In 2011, he joined the Gregor Mendel Institute of Molecular Plant Biology in Vienna as a group leader. During this time, he established his research program in root systems genetics and focuses on understanding which genes, genetic networks, and molecular processes determine root growth and its responses to the environment. In 2017, he came to the Salk as an Associate Professor in the Plant Molecular and Cellular Biology Laboratory. He is also part of the Integrative Biology Laboratory.
Postdoctoral Fellows

Christophe Gaillochet

Postdoctoral Fellow

Christophe Gaillochet, originally from France, obtained his PhD from Heidelberg University, Germany in the group of Prof. Jan Lohmann. During that time, he investigated the molecular networks underlying stem cell activity and differentiation at the shoot apical meristem. As a postdoctoral researcher in the Busch lab, Christophe is now interested in further understanding the regulatory control of plant responses to temperature and the genetic basis for plant adaptation.

Nicole Gibbs

Postdoctoral Fellow

Nicole completed her PhD at the University of Wisconsin-Madison under the supervision of Dr Patrick Masson, where she worked to identify the mole?cular response of plants to polyamines. She started in the Busch lab in June of 2018. Her current research focuses on using natural variation to characterize microbial volatile organic compound impact on plant root growth and development.

Wenrong He

Postdoctoral Fellow

Wenrong received her Ph.D. from Peking University, China, where she focused on identifying small molecule inhibitors of phytohormone pathway by chemical genetics. She joined the Busch lab in June 2017. She is interested in 1, Identifying novel factors regulating root growth, development, and architecture via chemical genetics combined with GWAS and phenotypic imaging system. 2, Dissecting the molecular mechanism of climate-associated genes regulation. She aimed that her research can make the world a better place by improving crop advancement under natural condition and environmental adaptation to global climate change by studying root system, the backbone of plants, with the help of powerful robot and high through-put imaging system of Busch lab. Outside the lab, Wenrong enjoys painting, photography, boxing, and Karate.

Baohai Li

Postdoctoral Fellow

Baohai, from China, received his Bachelor (2004) of Agronomy in Nanjing Agriculture University and PhD (2010) of Plant Nutrition from the University of Chinese Academy of Sciences (Institute of Soil Science). After his PhD, he joined in Institute of Soil Science as an Assistant Professor until 2013. His work was to understand the plant behavior and responses at high ammonium stress by screening and characterizing the Arabidopsis mutants. During this time, he visited the lab of Ute Kraemer in Ruhr University Bochum in Germany for six months. From April 2013, he received JSPS postdoc fellowship to join the lab of Toru Fujiwara in University of Tokyo in Japan. By characterization of the low calcium sensitive mutants in Arabidopsis he revealed a new molecular component LOTR1(Lord Of The Rings) in Casparian strip formation and a novel role of suberin as an apoplastic diffusion barrier at sites of lateral root emergence where Casparian strips are disrupted. From February 2016, he received the Lise-Meitner senior postdoc fellowship to join the Busch lab in Gregor Mendel Institute (GMI) of Austrian Academy of Sciences and moved to the Busch lab in Salk Institute at January 2018. His project is to investigate the genetic basis of root growth variation in response to the toxicity of heavy metals (iron and cadmium) at either intraspecies levels or interspecies levels.

Anna Malolepszy

Postdoctoral Fellow

Anna comes from Poland. She received her PhD at Aarhus University in Denmark where she was working on legume-rhizobia symbiosis and was involved in the establishment and screening of Lotus japonicus mutagenized population and investigation of a novel nodulation mutant. Subsequently she moved to the Busch group at GMI in Vienna, Austria for her postdoctoral studies to investigate the species-specific mechanisms of adaptation of Lotus root to the nutrient deficient conditions using association genetics. In October 2017 she has joined the Busch group at SALK to continue her project.

Charlotte Miller

Postdoctoral Fellow

Charlotte recently moved to San Diego from England where she worked at the John Innes Centre in Norwich. During her PhD her research was aimed at understanding the genetic regulation of stem mechanical strength is Brassica species and Wheat. Her post doctoral research was focused towards the genetic control of seed size and oil content in Brassica napus. In the Busch lab she will be exploring natural variation in several species to understand root growth. Outside of the lab she loves to play the piano and guitar and have recently taken up ceramics! Charlotte also enjoy cycling, hiking and spending as much time as possible at the beach.

Takehiko Ogura

Postdoctoral Fellow

Takehiko Ogura completed his PhD training in Laboratory of Bioregulation Chemistry, Division of Applied Life Science, Graduate School of Agriculture in Kyoto University, where he studied mode of actions of insect molting hormones using chemical biology approach. After that, he has studied physiological functions of the plant hormone auxin capitalizing chemical biology. In Busch lab, his research subject is the regulatory mechanism of root morphology by auxin and its involvement in the responses to various environments.

Matthieu Platre

Postdoctoral Fellow

Originally from France, Matthieu obtained his PhD at the Ecole Normale Supérieure de Lyon in 2017. He was part of the cell signalling and endocytosis group mentored by Yvon Jaillais. During his PhD, he analyzed membrane electrostatics organization in plant cells and its role in cell-signaling and development. His main scientific question is how plant adapt to their environment. Matthieu joined the Busch’s lab in order to decipher the molecular gene network related to plant nutrition.

Qingqing Xie

Postdoctoral Fellow

Qingqing Xie received her PhD degree in Analytical Chemistry from Xiamen University, China. And during her PhD study, she studied the functions of heavy metal transporters as a visiting PhD student under the mentorship of Dr. Julian I Schroder at University of California, San Diego. Later, she was a postdoctoral fellow of Huazhong Agriculture University and study the uptake and detoxification mechanisms of heavy metal in plants.

Erin received her BS degree in Biochemistry from the University of Minnesota-Twin Cities where she worked as a lab technician to domesticate a new oil seed crop. She soon left the Midwest to follow the sunshine to San Diego where she participated in C. elegans host-pathogen research at UCSD. Erin joined the Busch lab in 2017 as a research assistant to rejoin the plant community. Along with other postdocs in the lab, she is currently studying protein-protein interactions involved in Arabidopsis root growth in iron deficiency conditions. When she’s not tending to plants, she enjoys biking, hiking, and trying new beers at SD breweries.
