Parasite life history strategies within the host, especially the timing of replication and transmission, influence disease severity and spread. I study how subtle differences in ecology within and outside the host can generate dramatic differences in parasite strategies. My research program uses two major approaches: Building ecologically-detailed models to ask when and why particular strategies […]

My group studies cell envelope stress responses of Gram-negative pathogens. We are defining regulatory pathways and functional networks of enzymes involved in cell wall degradation, modification and synthesis as well as factors required for upholding outer membrane barrier function. We seek to understand these processes to gain insight into the mechanistic underpinnings of cell growth […]

Numerous studies demonstrate that vector-borne pathogens, such as viruses, influence host characteristics that result in altered host-vector interactions and enhanced virus transmission. We seek to determine the molecular mechanisms that underlie this phenomenon and use this knowledge to develop innovative control strategies using genetic and biochemical approaches. Current focuses are on changes in plant signaling […]

Assoc. Prof. Teresa Pawlowska discusses her lab’s work on food safety and fungi. The full text of the Cornell Chronicle story is below. CORNELL CHRONICLE STORY By Krishan Ramanujan A new grant will investigate how bacteria that live inside the cells of fungi may shape the biology, evolution, biodiversity and function of these fungi – […]

Prof. Corrie Moreau talks about digitizing the Cornell University Insect Collection. The full article appears below. CALS ARTICLE By Krishna Ramanujan As director and head curator of the Cornell University Insect Collection, Corrie Moreau has numerous tasks on her to-do list, including one that could last her entire career: digitizing the collection’s 7 million specimens. Digitization is a […]

The John Helmann lab has a new paper out, “A regulatory pathway that selectively up-regulates elongasome function in the absence of class A PBPs” in eLife.  LINK TO PAPER: https://pubmed.ncbi.nlm.nih.gov/32897856/

Associate Professor Clare Casteel (SIPS) has a paper out in Nature Plants, in collaboration with labs at UC Davis: “Organic management promotes natural pest control through altered plant resistance to insects” PAPER:  https://www.nature.com/articles/s41477-020-0656-9.epdf

The Moreau Lab studies the evolution of symbiosis between animals and their diverse microbial communities. Current work focuses on the benefits of microbial communities for ant hosts from nutrient provisioning to contributions to cuticle formation. Methods include amplicon sequencing, quantification, metagenomics, functional assays, experimental manipulations, and more. This work is deeply rooted in natural history […]

The long-term goals served by this project are mechanistic understanding of plant disease and development of broadly effective and durable means of control. The project seeks to structurally and functionally characterize a pathogen-activated host gene that plays a critical role in disease in a major crop species, and to ascertain the potential of strategies to […]

The Moeller Lab studies the evolution of symbiosis between animals and microorganisms. Our current work focuses on vertebrates’ co-evolutionary histories with bacteria through a combination of -omics approaches, gnotobiotic and microbiology experiments, and natural history. We are recruiting highly motivated and independent postdoctoral candidates with training in genomics, population genetics, microbiology, immunology, or related fields. Candidates interested in the genetic […]
