    Expert Express and Four O'Clock Forum: Tree Biomechanics


    During the“Tree Biomechanics” Expert Express and Four O'clock Forum, our panel will offer participants a unique view about how the subject has been studied, how the subject is being applied, and where they see the research going over the coming decades.  This session is scheduled for Tuesday, August 5, from 3:30pm-5:00pm.

    During this Expert Express, industry leaders and notable presenters from the conference will have the opportunity to deliver a very brief (5-8 minute) description of their research or topic of interest, followed by a one-hour break out session (Four O'clock Forum) where participants have the opportunity to talk about the individual presenter’s topic in a small-group setting. After the initial brief presentations, the presenters will fan out, where participants will then be able to approach speakers with their similar interests and move around the room to hear conversations about the various topics. This small group component is scheduled to last one-hour.

    Brian Kane has worked in arboriculture since 1988. He worked as a commercial and municipal arborist in New York before pursuing an academic career.

    Since 2004 he has worked at the University of Massachusetts in Amherst, MA, as the Massachusetts Arborists Association Professor of Commercial Arboriculture. At UMass, Brian teaches both field and lecture classes in arboriculture and studies tree biomechanics and tree worker safety.

    Brian recently completed his term as Chair of the Science and Research Committee. He has also served on the Educational Goods and Services Committee and as an Associate Editor and reviewer for Arboriculture and Urban Forestry.

    Brian is a Certified Arborist and has competed in several regional tree climbing competitions, placing fourth in New England in 2006.

    Frank Rinn studied physics at Giessen and Heidelberg University and wrote his thesis in 1986 about resistance drilling for wood and tree-ring analysis. In 1988 he started his own company, RINNTECH, for developing and applying equipment for dendrochronology and dendro-climatology, tree and timber inspection.

    Frank invented different methods and developed several machines and computer programs, such as resistance drilling, tree-ring measurement and cross-dating, dynamic tree analysis, sonic tree tomography, and sonic root diagnosis. He created, established, and owns national and international patents and trademarks, such as RESISTOGRAPH® and ARBOTOM®.

    Since 2001, he serves as voluntary Executive Director of ISA Germany, represented his chapter on several board meetings, joined the ISA Tree-Risk Panel of Experts and contributes to the corresponding BMP.

    Dr. Jason Grabosky is a professor at Rutgers University

    Dr. Ed Gilman received his Ph.D. from Rutgers University in 1980 in forest plant pathology and is a professor in the Environmental Horticulture Department at the University of Florida in Gainesville. He has assembled a unique urban tree teaching program for helping municipalities, contractors, arborists, educators, growers, landscapers, and others design and implement programs for promoting better tree health in cities. He conducts educational programs in tree selection, nursery production, and urban tree management nation-wide for a large variety of audiences. Dr. Gilman is a Florida chapter ISA past-president. He has published more than 96 scientific peer reviewed journal articles in his 30 years in academia and industry and has won numerous awards. His research emphasizes tree pruning, nursery production, anchorage, and tree establishment. He has published more than 150 technical articles in newsletters and trade magazines and annually presents research results to colleagues at professional meetings across the US and throughout the world. He is the author of six books and maintains an extensive web site on urban trees.
