Postdoctoral Fellows

En Li

Postdoctoral Fellow

Originally from China, En obtained her PhD from China Agricultural University in 2020, where her research focused on the roles of nucleosome organization and three-dimensional chromatin structure in maize growth and development. Following her PhD, She pursued two post-doctoral positions: one investigating the domestication of the Jasmonate pathway in tomatoes at the Institute of Genetic and Developmental Biology, Chinese Academy of Sciences, and another studying RNA modification in Arabidopsis at the University of Chicago. In September 2023, She joined Julie Law’s lab at Salk Institute to further her research journey. Her main points of interest are: 1) the molecular mechanisms of RNA-directed DNA methylation establishment, and 2) how chromatin modifications influence DNA repair.


Laura Martins

Postdoctoral Fellow

Laura Martins did her PhD in Reichheld lab at LGDP (University of Perpignan, France) where she worked on an iron-sulfur cluster protein belonging to the antioxidant enzyme family of glutaredoxin, the Arabidopsis GRXS17. The goal of her thesis was to better understand the role of this protein in root development and temperature adaptation by both in vivo and in vitro techniques, using biochemical, proteomic, microscopic, genetic and phenotypic approaches. She joined the Law lab at the Salk Institute in October 2019 to help, by using her background, in the characterization of factors involved in the RNA-directed DNA methylation (RdDM) pathway to determine the genetic and epigenetic mechanisms controlling DNA methylation patterns.

Fuxi Wang

Postdoctoral Fellow

Fuxi Wang received her PhD from University of Maryland – College Park in 2022. Her thesis work focused on understanding how the cell cycle is integrated into plant meristem development in Arabidopsis Thaliana. She worked on characterization of the TSO1 regulatory pathway in the shoot apical meristem and the root apical meristem using both genetic tools and single cell RNA sequencing. As a postdoctoral fellow in Julie Law’s lab, she will be exploring the roles of chromatin modifications in mediating tissue-specific patterns of DNA methylation using both genetic and genomic approaches.


Guanghui Xu

Postdoctoral Fellow

Guanghui Xu received his Ph.D. in Crop Genetics and Breeding in China Agricultural University in 2019. As a graduate student in Feng Tian’s lab (National Maize Improvement Center of China) he studied the genetic basis of maize domestication from a metabolomic perspective. By analyzing the metabolic evolution between maize and its progenitor, teostine, he identified many specialized metabolites that are involved in maize domestication and mapped candidate genes responsible for the maize metabolic domestication processes. As a postdoctoral fellow in Julie Law’s lab, he started to focus on the molecular mechanisms of DNA methylation establishment in Arabidopsis and is currently screening for novel factors involved in the function of CLSYs, which are locus-specific DNA methylation regulators.



Theresa received her Bachelor of Science degree in Computational and Systems Biology with a concentration in Neurosystems from UCLA. Theresa’s thesis work in Dr. Matteo Pellegrini’s lab focused on whole genome DNA methylation analysis methods using bisulfite sequencing and how methylation levels correlate with age. She joined Dr. Julie Law’s lab in 2023 where she is interested in analyzing genomics data to understand the mechanisms that regulate gene expression and suberin synthesis. Theresa is also a tennis player.


Matt Simenc


Mathew received his Bachelor’s in Botany from Humboldt State University and his Master’s in Biology from California State University, Fullerton. Mathew has a long-time love for plants and took interest in bioinformatics toward the end of his Bachelor’s program. For his Master’s thesis he focused on annotating fern genomes and the bioinformatic characterization of LTR retrotransposons. Mathew joined Julie Law’s lab in March 2020 to provide bioinformatics support for the Harnessing Plants Initiative at Salk.
Research Assistants

Joshua Eis

Research Assistant II

Joshua Eis received his Bachelors of Science in Molecular and Cellular Biology at the University of California, San Diego. During his undergraduate, he was a research assistant in Dr. Linda Holland’s lab at the Scripps Institute of Oceanography where he studied the role of FGF in establishing somite boundaries of Branchiostoma Floridae and how it compares to vertebrates. Additionally, he spent a summer in Dr. Emma Farley’s lab to study the role of the ZRS enhancer in expressing the Sonic Hedgehog Transcription Factor in mice. He also helped facilitate an upper division course called Eukaryotic Gene Expression under Dr. James Kadonaga. Eis joined the Law lab in April 2022 as a volunteer and began his Research Assistant I role in August 2022. Currently, he is working with Dr. Laura Martins to elucidate how the CLSY proteins are involved in establishing methylation patterns in the Arabidopsis thaliana genome via the RNA-directed DNA Methylation (RdDM) pathway.



Research Assistant II

Paloma received her Bachelor of Science through a joint program between CEU San Pablo University in Madrid, Spain, and the University of California, San Diego. Her bachelor’s thesis focused on characterizing the West Nile Virus RNA-dependent RNA polymerase. She moved to San Diego during her last year of undergraduate where she joined Jose Pruneda-Paz’s Cell and Developmental Biology lab, standardizing a method to increase CRISPR/Cas9 homologous recombination efficiency, using Arabidopsis Thaliana as a model. Paloma joined the Law lab as part of the Harnessing Plants Initiative (HPI), contributing to the development of different strategies for carbon sequestration in plants. For this, she uses confocal microscopy and sequencing techniques such as DAPseq, among others. She is also helping in the efforts of translating these traits into crop plants. In her free time, she’s out skateboarding, convincing herself that she will learn how to surf, and trying not to break any more bones.


Liam Sheedy

Research Assistant II

Liam Sheedy received his Bachelor of Science from the University of Massachusetts, Amherst in Biology. While at UMass he did an undergraduate honors thesis in a plant biology lab. His thesis involved increasing production of omega three fatty acids and overall oil yield in Camelina sativa for biofuel usage. Liam was also a part of the iCons program at UMass focusing on interdisciplinary research skills and collaboration. His work in the Law lab is with the Harnessing Plants Initiative (HPI), using genetic engineering approaches to identify novel phenotypes associated with root growth and recalcitrant biopolymers.
