Lab employees
Kate Holcomb
Project manager
Kate is the project manager for the Climate Adaptation and Mitigation Fellowship (CAMF) program, a multi-state outreach and education program that supports farmers and advisors to learn about and adapt to a changing climate. Kate has worked in agriculture for more than a decade, including founding and operating a year-round rooftop aquaponics greenhouse. She earned her B.A. from UMass Amherst and an MBA from the University of Southern Maine, where she focused on sustainability in small food businesses. Her work in farming prioritizes community education, grounded in the belief that a strong connection between the farm and the community makes local food systems more resilient.
Ian Farm
Lab manager
Ian’s work in agriculture began through working as a farm hand during his high school years in southern Maine. He went on to earn a B.A. in Ecology with a minor in Environmental Studies from Dartmouth College in New Hampshire. There, he researched agroforestry and plant-soil feedback, while continuing to work on farms and orchards in the area. As the laboratory manager, Ian’s work includes data management, research methods and equipment, site maintenance, and safety.
Post doctoral research associates
Dr. Janica Anderzén
Postdoctoral Research Associate
Janica joined the Agroecology Lab in May 2023 after earning a Ph.D. in Agroecology at the University of Vermont (UVM). For her Ph.D., Janica conducted research on socio-economic characteristics and impacts of agricultural diversification in smallholder coffee farmer communities in Chiapas, Mexico, focusing specifically on the multifunctional role of beekeeping in coffee systems. Her dissertation work formed part of a transdisciplinary, Participatory Action Research process with a coffee farmer cooperative and other partners. The experience strengthened her belief in the power of horizontal knowledge co-creation as a critical element of agroecological transformations. Prior to her studies at UVM, Janica worked in several human rights and environmental non-profits. In her new role as a Postdoctoral Research Associate, she’s excited to learn more about agroecological processes in the Northeast and deepen her skills as a transdisciplinary scholar. With deep roots in Finland, Janica feels the happiest in a forest or by a lake - camping, hiking, or paddling.
Dr. Olusegun Idowu
Postdoctoral Research Associate
Before joining the UMaine Agroecology Lab, Olusegun was a Postdoctoral Research Fellow at Kyoto University, Japan (from 2022 – 2023). He earned a MSc, and Ph.D. in Crop Science from Kyoto University, Japan (2016 - 2022). During his Ph.D., program Olusegun researched rice yield and quality under varied nitrogen fertilizer applications in different ecological environments. His study was encompassed fields experiments, pot experiments using growth chambers, using crop science and plant molecular concepts. Olusegun has worked as a consultant with Meiwa Co. Ltd., Japan and contributed to the promotion of the acceptance and utilization of biochar under the climate-smart Agriculture strategy of the United Nations (UN). Before moving to Japan, he worked with the National Center for Agricultural Mechanization (NCAM) in Ilorin, Nigeria as a soil scientist/agronomist. There, he contributed for the promotion of sustainable agriculture among farmers through indigenous agricultural technologies. In his work with the UMaine Agroecology Lab, Olusegun will contribute on research related to PFAS in agroecosystems, how to improve soil fertility and crop yield/quality, as well as to approaches to promote a healthy environment.
PHD Students
Sara Delaney
Ph.D. student in Ecology and Environmental Sciences
Sara earned her BS from Cornell University in Biological and Environmental Engineering and then served as a Peace Corps volunteer in rural West Africa. Her passion for working with farmers began there - living in a community where farming was a way of life. She completed her Masters in ‘Science, Society and Development’ at the Institute of Development studies in the UK, and then spent the next 13 years working with Universities, the UN, and non-profits on agriculture and food security programs in Africa, Asia and Latin America. Through this work she has grown increasingly interested in engaging with the challenges farmers everywhere are facing with climate change. Sara is excited to use her Ph.D. work to connect her practical experience with the latest science, and to conduct research on how advisory services work together with farmers to adapt agriculture to a changing climate.
Gladys Adu Asieduwaa
Ph.D. student in Ecology and Environmental Science
Gladys graduated from the ISARA Lyon University, France and the Norwegian University of Life Sciences, Norway, where she earned a double degree European Master of Science in Agroecology. During the course of her MSc, she was privileged to have undertaken an Erasmus exchange at the University of Kassel, Germany where she studied MSc Sustainable Food Systems. She worked with the French National Research Institute for Agriculture, Food and the Environment, where she simulated the impacts of climate change and scenarios of adapted cropping practices on the risk of brown rust development in winter wheat in some French regions. She also worked with the European Union Knowledge Centre consortium on Global Food and Nutrition Security, to structure existing knowledge about agroecology as a farming and food system in developing countries. She is passionate about Agroecology and Climate-Smart Agriculture measures that transform farm and food systems towards sustainability to promote food and nutrition security.
Ali Bello
Ph.D. student in Ecology and Environmental Science
Ali Bello hails from a rural district in Kano state, Nigeria, where agriculture is not just a profession but a way of life. Upon completing his high school, Ali's father, recognizing the challenges posed by climate change to the agricultural sector in African countries, advised him to pursue a bachelor's degree in agriculture, with the belief that Ali could be part of the solutions. This motivated Ali to study agriculture for his bachelor’s, where he specialized in crop science.
Ali joined the agroecology lab in 2022, where he completed a master’s degree (in 2024) and researched the effects of precipitation change on wild blueberries. He eagerly looks forward to extending his journey at the agroecology lab by pursuing a Ph.D.
Alexandra Scearce
Ph.D. student in Ecology and Environmental Science
Alex earned a B.S. in Ecology and Evolutionary Biology with a minor in Sustainability from the University of Tennessee at Knoxville. At UTK, she studied the interactive effect of fire disturbance and soil microbial composition on oak regeneration to inform management strategies. She was then employed with the USDA-ARS to conduct crop and integrated pest management research. Alex completed her masters with the Agroecology Lab in 2024, which focused on uptake of PFAS into plants to inform crop selection for contaminated agroecosystems. She is currently researching the strength of multi-trophic interactions and the role they play in responding to climate stress within wild blueberry, Vaccinium angustifolium, systems as a PhD student.
