Michelle Cleary
I am a Forest Pathologist working with native and alien invasive forest pathogens that threaten the economic and ecological sustainability of forests. I study the intimate relationships between fungal and oomycete organisms and trees, the intricacies underlying invasive biology, and mechanisms by which trees defend themselves against plant pathogens. Understanding biochemical- and genetic-based interactions of pathogens with their host trees and the environment is critical to maintaining healthy, sustainable, and resilient forests in a changing world. Our Forest Pathology group at Alnarp is working several of these aspects. In addition, several new projects in the group include various molecular, chemical and imaging techniques and tools for early detection and diagnostics to identify and monitor damaging agents in trees and forests.

Presentation

Senior Lecturer in Forest Pathology, Associate Professor (Docent)

Teaching

Currently, I teach 'Forest Health' in the course “Broadleaves - Forest dynamics, biodiversity and management for multiple use” (15 ECTS) and lecture in the course "Urban Forestry – management of urban forests and trees" (15 ECTS). I have previously lectured on various topics related to tree health in the courses “Plant Protection”, “Sustainable Forestry in Southern Sweden”, and "Phenotyping Technologies in Plant-environment Interactions – Integrated Analysis of Omics Data". I will also teach on upcoming courses in “Trees: structure and function” (15 HEC) and “Tree and Forest Health” (7.5 HEC) in the new International Bachelor Programme in Forest and Landscape Management. 

Research

During my 15+ years career as a Forest Pathologist, I have been conducting research on a broad array of forest pathogens, including root rot pathogens of conifers (Armillaria, Heterobasidion, Inonotus, and Phellinus); invasive forest pathogens including Phytophthora root dieases, ash decline, and white pine blister rust, canker and rust diseases of poplar and larch; and several native and introduced needle and shoot blight diseases of pine. 

Cooperation

I currently collaborate with Assoc. Prof. Johanna Witzell (SLU; invasive forest Phytophthora pathogens in forests, urban areas, nurseries, fungal endophytes and microbiome studies), Dr. Mateusz Liziniewicz (The Forest Research Institute - Skogforsk; ash dieback and larch canker disease). In addition, I collaborate with Assoc. Prof. Jonas Rönnberg (SLU; Heterobasidion root rot), Dr. Patrick Sherwood (SLU; biochemistry of host-pathogen interactions of trees; Diplodia shoot and tip blight) and Dr. Carmen Romeralo Tapia (SLU; tree microbiome, ash dieback, Phytophthora).

Among my international collaborators, currently I have projects running with Prof. Stephen Woodward (University of Aberdeen; foliar diseases of conifers and broadleaves, ash dieback, chemical volatiles for early detection of pests and pathogens, pathways of introduction for alien invasive species); Prof. Enrico Bonello (Ohio State University; spectroscopy-based tools for advanced phenotyping, tree chemical defenses in Fraxinus, sentinel plantations as early warning for new and emerging pests/pathogens), Dr. Simone Prospero (WSL; invasive Phytophthora diseases, Armillaria root rot), Assoc. Prof. Rein Drenkhan (Estonian University of Life Sciences; emerging pine needle diseases; forest Phytophthora pathogens), Prof. Tuğba Doğmuş Lehtijarvi and Dr. Funda Oskay (Isparta and Çankırı Karatekin Universities, respectively; pine needle diseases; Fraxinus foliar endophytes), Dr. Diana Marčiulynienė (Lithuanian Forest Research Institute; ash dieback), and Dr. Iryna Matsiakh (Ukrainian National Forestry University; forest Phytophthora pathogens in Ukraine, Fraxinus foliar endophytes).

Background

I did my forestry education in Canada at Lakehead University (1998-2001) and later obtained my PhD degree in Forestry (Forest Pathology) in 2007 from the University of British Columbia under the supervision of Prof. Bart van der Kamp and Dr. Duncan Morrison. My PhD thesis dealt with the biology and control of Armillaria root disease in the interior forests of British Columbia; specifically investigating differential resistance among conifers and resistance mechanisms operating in trees.

Between 2006 and 2010 I worked as the Regional Forest Pathologist for the British Columbia Ministry of Forests, Range and Natural Resource Operations, in the Southern Interior Forest Region based in Kamloops, British Columbia, Canada. There I served as the regional expert being responsible for and covering an area approximating 25 million ha (or ~30% of the provincial landbase); and worked with the forest sector and other key stakeholder groups on practical and operational issues as it relates to forest disease and sustainable forest management, including:

   ·   refined policies and practice standards to accomplish disease prevention and control

   ·  development and implementation of applied research and control projects to assess, evaluate and monitor impacts of disturbances, forest pathogen behavior, and the effectiveness of various forest disease management strategies

   ·  extension and training activities activities for the forest sector

Teaching in the subject Forest Pathology: Between 2003 and 2010 I taught undergraduate courses in Forest Pathology in different capacities as both term courses and distance education at the University of British Columbia and Thompson Rivers Unversity where I held an Adjunct position for 4 years. 

Post-Doc research: I came to SLU in 2011 as a Post-doc in the Department of Forest Mycology and Plant Pathology in Uppsala where I collaborated with Jan Stenlid and Malin Elfstrand on research with ash decline.

Current research: In 2015, I moved to my current Department at the Southern Swedish Forest Research Centre in Alnarp where I am one of three senior researchers in the Forest Pathology Lab along with Dr. Johanna Witzell and Dr. Jonas Rönnberg hosting a team of Post-docs, PhD students, and technical staff all working with diverse issues in forest pathology: pine needle diseases (Diplodia sapinea, Lecanosticta acicola); Heterobasidion root rot in production forests; Armillaria root rot, Dutch elm disease; Ash dieback; Phytophthora diseases in forests, urban areas and nurseries; pathogen damage in Christmas tree plantations; fungal endophytes in plants, soil and seeds; tree microbiome; chemical ecology; host-pathogen interactions; molecular diagnostics; and plant biosecurity. 

Supervision

Currently: I host two Post-doc researchers (Dr. Patrick Sherwood - an expert in chemical ecology; Diplodia, and VOCs analyses; and Dr. Iva Franic - an expert in sentinel plantations as a tool for early detection of invasive species; fungal community analyses in plants and seeds). I am main supervisor to two PhD students: Ida Nordström who is working with different techniques for early detection of invasive forest pathogens funded by the Swedish Research Council FORMAS, and Hanna Bernö who is working with ash dieback, ex-situ conservation of European ash and resistance breeding, funded by the Swedish Foundation for Strategic Research (SSF). I am also a co-supervisor to Noelia López-García who is working within the MSCA ITN project "PROTECTA" (main supervisor: Johanna Witzell). 

Previously: I have hosted 3 Post-docs (during 2016-2019): Tove Hultberg, ecological impacts of ash dieback; Marjan Ghasemkhani, host-pathogen responses/ash-dieback; Iryna Matsiakh, Phytophthora pathogens in Ukraine).  I have been co-supervisor to 3 PhD students: Li-Ying Wang (2014) "Impact of Heterobasidion spp. Root Rot in Conifer Trees and Assessment of Stump Treatment", Diem Nguyen (2015) "Effects of tree species diversity on foliar fungal distribution", and Marta Agostinelli "Fungal assemblages in forest trees-influence of internal and external conditions". I have supervised undergraduate projects (8 Masters and 5 Bachelors)  mainly on topics including fungal endophytic diversity in seeds, ash dieback, and Phytopthhora. Since 2013 I have also supervised a total of 18 international visiting students and researchers on short-term research stays.
