Ariena van Bruggen



CV: Ariena van Bruggen CV 2022




Dr. van Bruggen started her position as Professor of Plant Pathology and Epidemiology in the Emerging Pathogens Institute and the Department of Plant Pathology at UF in 2009, continuing in this position until 2018, when she retired as Emeritus Professor. Before her appointment at UF, she was Professor and Chair of Biological Farming Systems at Wageningen University, the Netherlands, from 1999 to 2009. Prior to that, she was Assistant, Associate, and Full Professor in Plant Pathology, with emphasis on vegetable crops, at the University of California in Davis, CA, USA, from 1986 to 1999.

At the beginning of her career, she was Associate Expert in Plant Pathology for the Food and Agriculture Organization in Ethiopia (1976-1980), Research and Teaching Assistant at Cornell University in Ithaca, NY (1980-1984), and Post-doctoral Associate in Environmental Biology at the Boyce Thompson Institute, Ithaca, NY (1985-1986).

  • Accomplishments

    While working at UC Davis, Dr. van Bruggen received two awards for her research accomplishments in 1993, namely the APS Ciba-Geigy award from the American Phytopathological Society for 'significant contributions to the advancement of knowledge of plant diseases and their control' and the Jakob Eriksson Gold Medal from the Jakob Eriksson Prize Fund Commission, Swedish Academy of Sciences, in recognition of ' your original and thorough work on the new disease, 'corky root' of lettuce, caused by a hitherto unknown pathogen, the bacterium Rhizomonas suberifaciens.' Part of this work was continued at UF, describing four new genera and three new species of related bacteria causing lettuce corky root.

    She also developed several simulation models and spatial distribution and risk models during her career and joined the Plant Health Panel of the European Food Safety Authority (EFSA) preparing risk models for invading plant pathogens. Several different pathogens were studied, with special emphasis on enteric human pathogens and the bacterium causing citrus huanglongbing (greening).

    She served as a member of the NRC committee of the National Academy of Sciences on Mycoherbicides for eradicating Illicit Drug Crops in 2010-2011 and was a member of the Scientific Council of Agrinnova, Turin, Italy from 2005 to 2022, and a member of the Jakob Eriksson Prize Fund Commission of the International Society of Plant Pathology from 2000 to 2022.

    In 2012, she became a Fellow of the American Phytopathological Society.

  • Teaching Profile

    Prof. Van Bruggen developed and taught a course on plant disease epidemiology and a colloquium series on the use of statistical methods in plant pathology at the University of Florida. She also participated in the discussion group One Health at the Emerging Pathogens Institute.

    At Wageningen University, she taught several courses in the area of Organic Agriculture, and at UC Davis, in Pathology of Field and Vegetable Crops.

    Prof. van Bruggen supervised 18 PhD theses as main advisor and 19 as co-advisor. She also supervised innumerable MS students at UC Davis, Wageningen University and the University of Florida.

  • Research Profile

    Dr. van Bruggen carried out fundamental and applied research on ecosystem health in relation to the invasion by plant and human pathogens. A healthy ecosystem is characterized by a dynamically balanced and diverse community of organisms, stability and resilience after disturbances, minimal losses of nutrients and energy, and sporadic outbreaks of pests and diseases. We hypothesized that the extent of oligotrophy, in terms of easily available carbon sources and mineral nutrients, largely determines the health status of an ecosystem. This concept was developed based on research results on the survival and spread of enteric human pathogens (Escherichia coli O157:H7 and Salmonella enterica) from manure to soil, water and plants. A probabilistic risk model was developed for the contamination of a lettuce crop by manure, soil, and water contaminated with E. coli O157:H7. Internalization of Salmonella enterica serovar Typhmurium in tomato leaves, stems and fruits was shown to occur from contaminated water and aerosols. Simulation models were developed for the survival of E. coli O157:H7 and Salmonella Typhimurium in manure, manure-amended soil and water.

    Besides research on ecosystem health and transmission routes of enteric pathogens, the integration of various temporal and spatial scales of ecological processes and the dispersal capacity of (re)emerging pathogens in agroecosystems have been recurrent themes in van Bruggen’s research projects. The dynamics of disease progress can be understood better when we take the response time into account for the different developmental stages of the pathogen in relation to the hourly dynamics of environmental conditions rather than average conditions. This was shown for the plant pathogens Bremia lactucae and Phytophthora infestans as well as for the human pathogens E. coli O157:H7 and S. enterica serovar Typhimurium.  This research has implications for the effects of climate change on pathogen growth. This work resulted in a simulation model for the potential effects of climate change on late blight development. In addition, simulation models were developed for peanut late leaf spot and citrus huanglongbing, as well as spatial distribution and risk models for citrus huanglongbing and black spot, banana Xanthomonas wilt (BXW), and blueberry twig blight. We showed that BXW is threatening food security in Eastern Africa and proposed changes in the management of this disease.

    Since 2016, Prof. van Bruggen has been interested in potential effects of the herbicide glyphosate on microbial communities in soil, plants, and animals and the consequences for plant and animal health.
