Elizabeth Brauer

Elizabeth Brauer completed the requirements for a Ph.D. degree in the Department of Plant Pathology and Plant-Microbe Biology at Cornell University in August 2015. She conducted her Ph.D. research in Sorina Popescu’s lab at the Boyce Thompson Institute, with a focus on kinase signaling networks in immunity. Liz developed large-scale methods to identify protein-protein interactions, and used these interaction networks to identify kinases with a role in immunity. By comparing the immune function of multiple kinases, Liz discovered a new form of basal immunity which is dependent on the presence of pathogen effectors. Liz also identified a link between ion homeostasis and basal immunity through her work on the Integrin-linked kinase 1 in Arabidopsis. While at Cornell, Liz received several awards including the Postgraduate Scholarship from the Natural Sciences and Engineering Research Council of Canada and the Barbara McClintock Award. Liz is currently a postdoctoral fellow at Agriculture and Agri-Food Canada in Ottawa where she is conducting research on the role of wheat receptor kinases in producing resistance to the devastating fungal pathogen, Fusarium graminearum.

2013 Alumni

Julia Crane

Julia Crane

Julia Crane completed the requirements for a Ph.D. degree in plant pathology from Cornell University in 2013. Her research was supervised by Dr. Gary Bergstrom and she collaborated closely with Drs. Donna Gibson of the USDA-ARS and Michael Frodyma of Novozymes Biologicals, Inc. For her PhD project, Julia used a combination of greenhouse, field, and laboratory techniques to investigate the ecology of a Bacillus biological control agent being developed to combat the wheat and barley fungal disease Fusarium head blight. She identified several major obstacles to successful disease control in field settings, which included the limited temporal longevity of a critical Bacillus-produced secondary metabolite on wheat surfaces, and the inadequate coverage of wheat surfaces by biocontrol spray applications. Following her PhD, Julia worked in a Temporary Service Technician position with the Cornell Plant Disease Diagnostic Clinic to develop molecular methods for oak wilt diagnosis and Phytophthora species identification. She also continued on in Gary Bergstrom’s lab in a Postdoctoral Associate position, for which she assisted in field assessments of small grains diseases, and the development of a real-time PCR protocol for quantification of myoctoxin-producing Fusarium chemotypes from grain samples. In August 2014 Julia will join Dr. Amanda Gevens’ lab at UW-Madison as a postdoctoral associate investigating the ecology and management of Helminthosporium solani, causal agent of silver scurf of potatoes.


Stephen Mondo

Stephen Mondo Stephen Mondo received his Ph.D. degree in 2013. He conducted his Ph.D. work under guidance of Teresa Pawlowska. His project was devoted to understanding factors that stabilize symbiotic associations in two focal systems: the Glomeromycota-Giomeribacter symbiosis, and the Rhizopus-Burkholderia symbiosis. Over the course of his work, Stephen determined that the Glomeromycota-Giomeribacter symbiosis is at least 400 million years old, yet remains non-essential to host survival. Through investigating patterns of endosymbiont adaptation, he discovered that endosymbiont genome reduction in this system is adaptive rather than degenerative as in other endosymbioses. While characterizing the Rhizopus-Burkholderia endosymbiosis, Stephen found that R. microsporus has been forced into dependence on its bacterial endosymbiont through bacterial control over expression of genes essential for host sexual and asexual reproduction. Currently, Stephen is continuing as a post-doc in the Pawlowska lab, where he is studying vegetative interactions in Mucoromycotina as well as following up on several of his Ph.D. projects. He anticipates to apply for academic positions in the near future.

Brian KingBrian King

Brian King completed the requirements for a Ph.D. degree in the Department of Plant Pathology and Plant-Microbe Biology at Cornell University in March 2012.  He conducted his Ph.D. research in Donna Gibson's program, with assistance from Gary Bergstrom, with a focus on evaluating the potential of plant pathogenic fungi and their enzyme complement for use in biofuel production using lignocellulosic digestion. His results showed that many plant pathogenic fungi are highly competent producers of lignocellulolytic enzymes and that their enzyme systems are uniquely geared toward preferred biomass sources depending on their pathogenic lifestyle.  The large-scale study is listed as the 13th highest accessioned article in Biotechnology for Biofuels 4:4 (2011) since its publication last year, indicating great interest among the scientific and industrial community, and providing the largest statistical analysis confirming host selectivity of lignocellulases in plant pathogens. He is currently at the Department of Plant Biology and Biotechnology at the University of Copenhagen, Denmark, as a postdoctoral associate.  His project is focused on developing the moss Physcomitrella patens as a model system for characterization and optimization of terpenoid biosynthetic pathways for high value medicinal metabolites as well as biofuel intermediates.
