Current activities

Mr Mic Julien is a Research Scientist at the CSIRO Long Pocket Laboratory in Indooroopilly, Brisbane, Australia.

He is responsible for research on:

  • alligator weed, Alternanthera philoxeroides
  • lippia, Phyla canescens.

Mr Julien is also responsible for leadership of activities in South America including field surveys for potential biological control agents, and taxonomy and biology studies of insects and pathogens for those weeds.

He is organiser and lead editor of a book Biological Control of Weeds in Australia which will have over 70 chapters. Each chapter will provide information about a weeds species or group of related species and the biological control activities that have been undertaken historically and for Australia.

Background

Mr Julien has been a researcher with CSIRO Entomology since 1974.

He began his career as a Rural Development Officer, with the Papua New Guinea Department of Agriculture, Stock and Fisheries (now Department of Agriculture and Livestock).

Mr Mic Julien is researching biological control agents of South American plants that are weeds in Australia.

Mr Julien has primarily researched biological control and integrated management of aquatic and terrestrial weeds.

He has extensive experience in international projects and has worked as a project director, consultant and trainer in the management of aquatic weeds in over ten countries.

He has been involved with several Cooperative Research Centres (CRCs) including the current CRC for Australian Weed Management helping to co ordinate activities, including:

  • short courses on biological control, initiating (lippia)
  • leading (alligator weed) projects
  • contributing to other projects on weed ecology and biological control.

For three years from April 2006 Mr Julien was OIC of the CSIRO European Laboratory at Montpellier, France where he was responsible for:

  • studies on fungi that are potential biological control agents for blackberry
  • identification of wheat strains that are resistant to Russian wheat aphid
  • post hoc studies of the efficacy of different populations of parasites from Europe that have been imported and released for biological control of insect pests in the United States of America (USA) and elsewhere, in collaboration with the United States Department of Agriculture (USDA)
  • studies on fungi that may have potential as biological control agents for gorse, Ulex europeaus in collaboration with Tasmanian Institute of Agricultural Research.

Academic qualifications

Mr Julien's academic record includes:

  • Diploma in Agriculture from Hawkesbury Agricultural College, (now University of Western Sydney)
  • Bachelor of Science from the University of New England, Armidale
  • Master of Science from the University of Queensland, Brisbane, Australia.

Achievements

Mr Julien was one of the team that developed a very successful biological control of the floating aquatic weed salvinia.

He made the initial releases of the alligator weed flea beetle in Australia and studied its impact as it eliminated large floating mats of alligator weed from rivers in the Sydney, Australia, region.

He led a project that resulted in the control of water hyacinth on the Sepik River in Papua New Guinea and was a consultant, advisor and trainer for the biological control of water hyacinth on Lake Victoria in Kenya.

Mr Julien has over 90 scientific publications, more than half in refereed journals.

He has helped coordinated four international conferences including the XII International Symposium on Biological Control of Weeds held in France in 2007, edited several proceedings, and complied and edited the book Biological Control of Weeds: A World Catalogue of Agents and Their Target Weeds, first published in 1982, with three updated editions.

He has received several scientific achievement awards in recognition of his work including:

  • UNESCO Science Prize 1985, awarded to the salvinia research team
  • AIDAB Award for Excellence in Overseas Development Assistance 1988, as part of the salvinia team
  • Eureka POL Prize for Environmental Research 1990, as a member of the CSIRO Entomology, Biological Control of Weeds
  • Liverpool City Council's Fraser Environment Award 1992, for his work with alligator weed.
