Erin Bell is a PhD student with the Department of Forestry and Natural Resources at Purdue University. She earned her undergraduate degree in Biology from Carroll College in 2014 and her master’s degree from Miami University in 2020. Prior to enrollment at Purdue, she gained experience in ecological research in Idaho and Montana with the US Forest Service before moving to work in the diverse ecosystems of Hawai’i. Working with Maui Forest Bird Recovery Project and their partners since 2019, she developed a passion for native plants and the unique relationships they hold with Hawai’i’s forest birds. Erin is interested in pursuing research that explores forest restoration techniques that benefit native birds, land managers, and plant biodiversity to inform and influence management decisions.
Solomon Champion is a PhD candidate in the Botany Department at the University of Hawai‘i at Mānoa, studying the genetics of native Hawaiian tree species. Solomon’s interests are in genomics, phylogenetics, and evolution. He is using population genetics to elucidate population structure within the Hawaiian sandalwoods as a whole and to identify hybrid individuals. Solomon is using physiological and genomic methods to characterize genotypic variation at the individual and population levels. He hopes this research helps answer practical questions about phenotypic plasticity, local adaptation and hybridization within ‘iliahi.
Kelly French is a PhD student at Purdue University, Department of Forestry and Natural Resources. Kelly earned her BA in Biology from Colgate University in 2015 and worked for four years in human genetics while spending most weekends working on her family’s 450-acre Tree Farm in Maine. This drove her to return to school to study forestry, and in 2021 she graduated with her MS in Forest Resources from the University of Maine where she studied tree ecophysiology. During her PhD, Kelly is especially interested in investigating tree water and carbon relations in ‘iliahi and various host species, while developing adaptive management strategies to minimize drought stress. She plans to use physiological parameters to inform longer-term species growth responses, and is interested in how macroclimate, microclimate, and elevation influence these responses.
Jennipher Himmelmann is a Resource Assistant with the USDA Forest Service Urban and Community Forestry Program and recent addition to the Tropical HTIRC staff. She is based on Hawaiʻi Island where she earned her undergraduate degree in Environmental Science from the University of Hawaiʻi at Hilo and began her career in forestry as an intern. During her time at UH Hilo, she worked in the Listening Observatory for Hawaiian Ecosystems identifying forest bird vocalizations to train machine learning algorithms, and completed a Senior Thesis under the Spatial Data Analysis and Visualization Lab. Jennipher loves the opportunity to apply her skills in GIS and communications to provide administrative and technical support to partners in tropical forestry conservation in the place she calls home.
Asa McCurdy is a PhD student with the Department of Forestry and Natural Resources at Purdue University. He earned his undergraduate degree in Plant Sciences and Technology from the University of Missouri-Columbia in 2020 and his master’s degree in Botany and Plant Pathology from Purdue University in 2023. Asa’s PhD project focuses on the link between nonstructural carbohydrate (NSC) and chemical defense dynamics of ʻōhiʻa trees to predict their resistance to Rapid ʻŌhiʻa Death, a destructive fungal pathogen complex. Asa is collecting samples from mature ʻōhiʻa trees to quantify NSC reserves and chemical defenses throughout the year and using this foundational knowledge to inform subsequent field and greenhouse trials. While Asa’s thesis will focus on NSC dynamics, collaboration with members of the Trowbridge Lab at the University of Wisconsin-Madison will elucidate defense compound dynamics. Asa aims to use these NSC and chemical defense compound data to inform decision making for ROD mangement and mitigation stratgeies.
Tawn Speetjens is a PhD student at Purdue University in the Department of Forestry and Natural Resources (FNR). He was born and raised in Honokaʻa on the Big Island of Hawaiʻi, and graduated from the University of Hawaiʻi, Hilo in 2009 with a BS in Biology, and from Purdue University in December 2022 with a MS from the Department of Forestry and Natural Resources. He has worked throughout diverse ecosystems in Hawaiʻi with highlights that include working for the US FWS on Laysan Island in the northwestern Hawaiian Islands, banding forest birds at the Hakalau National Wildlife refuge, and conducting watershed management with the Kohala Watershed Partnership. He also worked as a forester and nursery manager for the Hāloa ʻĀina Reforestation Project where he was introduced to the unique challenges of growing Hawaiian sandalwood species (ʻiliahi). Tawn has a passion for growing native plants of Hawaiʻi and is interested in ecological restoration and commercial production of ʻiliahi and native Hawaiian natural resources. He led development of a S. paniculatum propagation protocol that was published in Tree Planters Notes in 2021. His MS research examined the effects of fertilizers and host pairing on nursery production and field establishment of S. paniculatum and he published the first chapter of his thesis in the journal Forests in 2023. Tawn continues to work with S. paniculatum in his PhD research as he explores the physiological mechanisms that underlie the ʻiliahi-host connection.
Aaron Wehrman completed his MEM (Masters in Environmental Management) degree in 2024 at the University of Hawai‘i at Mānoa. He was born and raised on Oahu and graduated from the University of Hawai‘i at Hilo with a BS in Environmental Science in 2022. Aaron started his undergraduate work in Marine Science but made a transition to applied terrestrial ecology. He worked with Dr. JB Friday, Dr. Travis Idol, and the Department of Hawaiian Home Lands on an Acacia koa reforestation project on Mauna Kea, studying the effectiveness of reforesting koa in a gorse dominated landscape. Aaron is extremely grateful to the Hau‘oli Mau Loa foundation for funding his education and research.
Pandu Wirabuana is a PhD candidate at the UH Mānoa. He received his BS and MS from Universitas Gadjah Mada, Indonesia. Pandu has worked for 10 years in Indonesian tropical forests before starting his PhD program. He has experience working on mangrove restoration and plantation forest management with eucalyptus and albizia. Pandu has a strong background in forest growth and yield. He started his PhD program in 2022, working with Dr. Travis Idol as his supervisor. His research focuses on mixed stand management between ʻiliahi and host species in Hawaiian tropical dry forests, specifically addressing the balance of competition, facilitation, and parasitisim between ʻiliahi-host at the stand level. Pandu is writing his dissertation and planning his final defense for 2025. His dissertation committee is comprised of Drs. Travis Idol, Douglass Jacobs, JB Friday, Michael Saunders, and Kasey Barton.
