UTS-AUSGEMLaunch14-207Toni Chapman Ph. D.

Toni is a molecular bacteriologist (Ph.D. 2005) working with animal, plant and human pathogens at the New South Wales Department of Primary Industries, Centre of Excellence for Animal and Plant Health located at the Elizabeth Macarthur Agricultural Institute in Menangle, Australia. Toni’s work includes characterization of pathogens including E. coli, Clostridium difficile, Streptococcus suis and Staphylococcus aureus using molecular tools with a focus to understand gut microbial communities and develop probiotic/beneficial microbial formulations to combat these pathogens. Toni’s Plant Biosecurity research and diagnostics is focused on understanding and identifying bacterial pathogens through traditional and genomic identification technologies. This includes understanding endemic and exotic plant pathogens and developing improved identification, diagnostic, and surveillance tools for plant pests to provide a better biosecurity response. Toni’s primary target pathogen is Xanthomonas citri subsp citri. In addition, development of a probiotic diet to increase the efficiency of the Queensland fruit fly sterile insect technique (SIT) is underway. This pest is a biosecurity concern, as it affects Australian borders and our export market.


C. CruzChristian Cruz Ph. D.

Christian D. Cruz is originally from Ecuador, a top biodiversity-rich country in South America. He attended the Zamorano Pan-American School of Agriculture, in Honduras, where he received a B.S. degree in Agronomy. He then earned his M.S. in plant pathology at The Ohio State University, where he developed a strong interest in emerging plant diseases. In 2009 he joined the Department of Plant Pathology at Kansas State University where he worked on the emerging wheat blast disease as a doctoral and later as a post-doctoral research associate. The wheat blast disease is a high consequence plant pathogen that has put increased pressure on food security in developing economies and has the potential to lower standards of living in developed economies. During his time at K-State, he has provided leadership and played a major role for all of the research and extension activities in North and South America. He has been most interested in investigating the ecology and epidemiology of the wheat blast pathogen, and understanding the components of wheat blast resistance.

imageGrant Smith

Grant is a Plant Pathologist at Plant & Food Research in Lincoln (just south of Christchurch) with considerable experience in diagnostics and biosecurity in both Australia and New Zealand. For many years he worked for BSES in Brisbane developing and applying molecular diagnostic assays, principally for viral and bacterial pathogens of sugarcane. Grant was also responsible for the quarantine of both imported and exported international sugarcane germplasm, as well as the quarantine of breeding germplasm being transferred between regions in Australia. Grant ran his first RT-PCR experiments in the late 1980s and was one of the early publishers on PCR of dsRNA, duplex RT-PCR and bacterial ITS region diagnostics. His research interests grew to include bacterial and fungal pathogens, insects, monocot tissue culture and plant transformation-gene expression systems. Grant led the research teams which developed and field tested transgenic sugarcane under both the GMAC and OGTR systems, proving that viral resistance could be successfully introduced into elite sugarcane cultivars.

Grant moved to Lincoln in 2003. For seven years he was the Program Manager of B3, the Better Border Biosecurity Research Collaboration, which was the largest research initiative in New Zealand at that time, comprising over 40 projects in five themes. His current research interests include developing, improving and deploying plant biosecurity diagnostic platforms and response tools, understanding and exploiting pathogen genomes and developing new nanotechnology-based platforms and materials. He has published widely, including 12 invited book chapters, has two granted patents describing the Smartsett® tissue culture system and is a senior editor for the Springer science journal, Australasian Plant Pathology. Grant also holds an MBA in Technology Management from Deakin University, is a certified Project Management Professional (PMP), and is a senior contributor to the GERDA global response and eradication database.

Barbara Valent Photo 3 for ASPBBarbara Valent Ph. D.

Barbara Valent, Distinguished Professor of Plant Pathology at Kansas State University, earned a Ph.D. in biochemistry from the University of Colorado. She received an NIH National Research Service Award for post-doctoral training as a yeast molecular geneticist at Cornell University. While there, she began developing the rice blast fungus, Magnaporthe oryzae, as a model fungal plant pathogen. Dr. Valent joined the DuPont Company in 1985 to pursue rice blast research and develop novel control strategies for this pathogen, which remains a global threat to rice production. She rose to Research Fellow, the top scientific position within DuPont, before moving to Kansas State University in 2001. She is a Fellow of the American Phytopathological Society (APS) and of the American Association for the Advancement of Science (AAAS). Career highlights include service on the Board of Trustees for the International Center of Tropical Agriculture in Cali, Colombia. Dr. Valent and her colleagues have been the “first” or contributed significantly to several fundamental advances. Her laboratory was the first to identify and clone both a fungal avirulence gene and corresponding rice resistance gene. They demonstrated that the products of these two genes physically interact to trigger resistance, a finding with important implications for engineering enhanced disease resistance in plants. Other results include new fungicide targets for chemical control of fungal diseases, a patented fungal glue (“Spore Tip Mucilage”) that sticks to hydrophobic surfaces including plant surfaces and DuPont’s Teflon, and strategies for deploying rice resistance genes using molecular markers for analysis of the fungal population structure. Currently, Dr. Valent’s laboratory is applying functional genomics and advanced techniques in cell biology to understand how specialized biotrophic hyphae invade and hijack living rice cells to cause blast disease. She has become a leader in promoting research on wheat blast, a disease that recently emerged in South America and now threatens global wheat production.
