I am broadly interested in biological processes that mediate the molecular interplay between plants and microbes. In the past two decades, I led an interactive group of postdoctoral, graduate and undergraduate students who are interested in exploring novel phenomena in bacterial pathogenesis and disease susceptibility in plants. In addition, I teach graduate classes on plant and microbial biology and contribute to the large scientific community through serving on a variety of committees.

I initially joined the He lab to study the potential role of peroxisomal proteins in pathogen defense, however, transitioned to the lab manager position after the birth of my first son. Now, it is my job to make sure the lab runs efficiently, a feat mostly accomplished by managing our undergraduate assistants and keeping the lab stocked with supplies. As a former researcher, I have unique insight into project management and how a lab operates. This allows me to anticipate the needs of fellow lab members and guarantee that they have the supplies they need when they need it.

Innate immune responses offer protection against a broad-range of microorganisms and potential pathogens. I am interested in dissecting plant innate immunity to identify novel contributing factors in host susceptibility to refine our current understanding of plant-microbe interactions.

With great sadness we say good bye to our friend and colleague, Dr. Alex Brutus, who passed away December 31, 2017 after a long and courageous battle with the incurable disease ALS (amyotrophic lateral sclerosis or Lou Gehrig’s disease). Alex was an inspiring scientist, a genuine friend, and a caring husband and father. Alex’s boundless passion for science and creativity will always be a part of the He lab.  Although Alex’s illness hampered completion of his postdoctoral research, he was an important contributor to several projects, including the following published works:

Using a reverse genetics approach, I study the function of Arabidopsis genes whose expression are affected by the bacterial elicitor flg22, the bacterial toxin coronatine, and/or the salicylic acid analog BTH.

I am generally interested in signal transduction processes that allow plants and other organisms to perceive changes in their environment. My research focuses on elucidating the molecular species regulating the generation and maintenance of calcium signals during plant-pathogen interactions and how abiotic factors can influence this process on the cellular and molecular level.

Previous studies in our lab indicate that plant-microbe interactions are influence by a number of environmental conditions, including temperature and humidity. As average global temperatures increase, our understanding of the connections between elevated temperature and pathogenesis is increasingly important for effective crop management. Within this context, I'm interested in the molecular and cellular "crosstalk" that occurs when plants are simultaneously challenged by pathogen infection and elevated environmental temperature.

I work with Pseudomonas syringae Type-III effectors, which suppress plant immunity during infection.

My research focuses on studying plant-microbiota-environment interactions under biotic and abiotic stresses. Using a gnotobiotic plant growth setup, I am studying mechanisms of microbiota functions in enhancing plant health and growth and evaluating the roles of small molecules from defined microbial communities in mediating host processes.

My research is currently focused on understanding the mechanisms by which PAMP-triggered immunity is able to prevent pathogen establishment and growth. I am also investigating the variability of resistance to Pseudomonas syringae encountered in different natural accessions of Arabidopsis. Finally, a third project in which I am involved focuses into engineering new resistance pathways in plants.

The overall goal of my research is to understand how the bacterial pathogen Pseudomonas syringae infects plants. My first project is aimed at engineering jasmonate receptor mutants that have reduced sensitivity to coronatine, but preserve responsiveness to endogenous jasmonate. My second project is to clone Arabidopsis genes that, when mutated, restore the virulence of coronatine-deficient mutants of P. syringae bacteria.

Microbial colonization can offer significant benefits to the overall health of a host plant. However, our fundamental understanding of the mechanisms underlying microbial assembly, activity, and recruitment is limited. To harness the power of colonization by beneficial microbial communities in agriculture, we must obtain a holistic understanding of the interactions that occur between the host plant and colonizing microbes. To that end, I’m interested in studying the mechanisms by which plants control the quantity and content of the leaf microbiota, as well as how microbe-microbe interactions further influence community assembly.

My research focuses on unraveling the molecular mechanisms in which a plant microbiome influences host processes. The role of a microbiome on plant development and innate immunity are of particular interest to my research.

My research focuses on the interaction between Pseudomonas syringae  pv. DC3000 and Arabidopsis thaliana and how local infection and  activation of defense systemically disrupts plant growth and movements. By studying the interconnected nature between plant  pathogens, defense, and development, we can gain a broader insight  into the molecular mechanisms that regulate plant behavior.
