Lab Staff and Technicians
Aloha! I am a Junior Extension Agent in Agroforestry with the CTAHR TPSS Indigenous Cropping Systems Lab. In my role, I coordinate and support a variety of projects that our lab leads, focusing on sustainable farming practices and community-based agroforestry initiatives.
My background blends environmental education, ʻāina-based learning, and community outreach, with a strong emphasis on program development and coordination. I’m passionate about connecting people to the land and empowering communities to engage in sustainable practices.
Outside of work, I enjoy spending quality time with ʻohana and friends, exploring the outdoors, crafting, and working on various nonprofit or home improvement projects. You can reach out to me at: hooulula@hawaii.edu.
My name is M.J. I hold an A.S. in Tropical Forest Ecosystem and Agroforestry Management and am currently a junior majoring in Biology, with a focus on ecology, evolution, and conservation. At the Indigenous Cropping Systems Laboratory at Komohana, I work hands-on with the propagation and care of traditional canoe crops such as ʻawa, kō, ʻulu, and tī, as well as native plants and trees. I also help manage the canoe crop–based germplasm site at Waiākea and am currently workingunder the guidance of Dr. Noa Kekuewa Lincoln to build a comprehensive living collection of Hawaiian kō. In addition, I support ongoing research efforts at the lab.
My interests center on traditional Hawaiian agroforestry systems, with a strong focus on soil health as wealth and the genetic preservation of crops that have sustained peoples across the Pacific for millenia. I am particularly interested in work that supports food sovereignty and land stewardship grounded in ahupuaʻa-based management and regenerative agroecological practices that prioritize long-term ecosystem health for Kānaka ʻŌiwi communities.
Outside of the lab, I spend time in the field hiking, camping, fishing, and farming, experiences that deepen my ecological perspective and reinforce a place-based approach to research.
Humble greetings, kākou! I am an aspiring farmer, interested in exploring the ways our Hawaiian ancestors cultivated foods and managed for natural resource abundance, otherwise known as ʻāina momona.
I am the Project Coordinator, managing 23 acres at Kukaniloko, Wahiawa, O'ahu where we are working to implement community engagement and ecological restoration, leveraging a "vegetative continuum" to demonstrate the spectrum of effects and benefits from different ecological end states. My mission is to inspire others in perceiving the abundance present within themselves and in their surrounding environment, which was realized through my experience with the ICS lab. I live by the ʻōlelo noʻeau, “ma ka hana ka ʻike” (in doing, one learns), because the reciprocal relationship we develop with the land is a reflection of ourselves and our true nature and spirit.
For my masterʻs thesis, I explored the nutritional requirements of a traditional staple crop, breadfruit, or ʻulu in Hawaiian. ʻUlu has long represented abundance in the Hawaiian culture, as the historical accounts of this tree parallels with stories of famine. ʻUlu has become my greatest mentor and teacher throughout my academic journey, teaching me the values of reciprocity, lōkahi (balancing mind, body, and spirit), and abundance already present in our ecosystems.
Brian "Ioane" Jahn lives on Oʻahu in Wahiawā, Kūkaniloko, where he works to strengthen indigenous food systems, community resilience, and cultural preservation. He is the Program Coordinator for both Huakaʻi ʻIke ʻĀina (HIʻA) at the University of Hawaiʻi–West Oʻahu and the Ke Ō Mau Center for Sustainable Island Food Systems within the University of Hawaiʻi system.
In addition to having a background in Hawaiian Studies and ʻōlelo Hawaiʻi, Ioane holds a degree in Sustainable Community Food Systems (SCFS) from the University of Hawaiʻi–West Oʻahu. He also serves as President of ʻĀina Kaiāulu, a 501(c)(3) educational non-profit organization. Through this work, he helps facilitate the Ka Hiapo learning farm at Kūkaniloko, where education, ecological stewardship, and cultural preservation intersect to empower the local community.
A proud father of three keiki, Ioane is passionate about sustainable agriculture, food sovereignty, and the preservation of ʻike kūpuna. He enjoys farming, surfing, and studying place-based astronomy, deepening his connection to the land, ocean, and sky in alignment with ancestral knowledge.
Aloha, my name is Evan Kamber - I practice organic Agroforestry implementation, design, and maintenance in Hilo, Hawai’i. Grounded in observation and guided by teachings embedded within Hawai’i’s historical Agroforestry systems, the research consists of creating ideal environments for cultivating indigenous microorganisms using locally sourced byproducts and plants, weaving native plantings into Agroforestry systems as cover crops and pollinators, and helping make culturally relevant food crops more accessible to our local community. The research is collaborative and multidisciplinary in nature and strives to contribute solutions that enhance food security through the (re)establishment of Agroforestry systems throughout Hawai’i. Evan Kamber is a site technician at the partnering demonstration agroforestry site located at OK Farms. Evan is deeply knowledgeable about natural farming methods, growing canoe crops, and agroforestry. The site is supporting the active lab projects such as "Evaluating Nānea as an Indigenous Cover Crop" and "Understanding Barriers to Agroforestry Transitions."
Elisa has managed the Komohana Tissue Culture facility, which has been a critical support for indigenous crops in Hawai'i, propagating breadfruit, banana, sweet potato, kalo, and other crops. Over the past 5 years, she has produced over 12,000 breadfruit trees!
PostDoctoral Students
I am recently finished my PhD in the Tropical Plant and Soil Sciences Department at UH Mānoa, studying the formation of volcanic soils here in Hawai'i. My research looks at the evolution of soil from beginning to end, from fresh lava rock to highly weathered oxisols, using Hawai'i as a model system. This biogeochemical work was combined with historical data to understand how Native Hawaiian agroecology related to soils across the state.
This work caught the attention of the National Resource Conservation Service (NRCS), which is interested in incorporating traditional land management concepts into their ecosystem process models. I am now working with NRCS to further work on Hawaiian soil systems, traditional agriculture, and federal policies and programs.
Based in Hilo on Hawai'i Island, I am working with Dr. Lincoln and other ICS lab members at the Komohana Research Extension Center where we are conducting various soil analyses, investigating the connection between traditional Hawaiian agriculture systems and the natural soil fertility of the land, and having pau hana volleyball matches when the work gets tough. Feel free to email me any time: thaensel@hawaii.edu. Aloha!
PhD Students
Talofa! I'm a PhD student from Samoa working on ulu quality and postharvest. The goal is to improve harvest and postharvest handling practices that can prolong ulu shelf life and in turn improve profit for breadfruit farms and farmers. I am in the field every two weeks or weekly with other ICS lab members to collect data, harvesting, pruning, fertilizing, and other tasks. I also work closely with USDA-PBARC in Hilo to do ulu nutrient analysis, fruit edible coating and near infrared spectroscopy (NIR) analysis.
If you are interested in knowing more on ʻulu and want to come out with us on a field day, email me at: autufuga@hawaii.edu. Faafetai!
Aloha! I am a PhD student in the Tropical Plant and Soil Sciences Department at UH Mānoa
studying the integration of native plants into agricultural systems to support sustainable agriculture. My work is focused on a native Hawaiian legume, nānea (Vigna marina), in dryland kalo production systems. This research will involve some of the first recorded measurements of biological nitrogen fixation in nānea, development of management guidelines for establishment of nānea in ag settings, and measurements of crop yield, soil health indicators and arthropod biodiversity under nānea cover cropping.
I hold a B.S. In Entomology and Plant Science from Cornell University, where I researched the
functional ecology of huntsman spider locomotion and an MSc in Plant Science from California State University, Fresno, where I developed in vitro and traditional grafting protocols for salt-tolerant prickly pear cactus. Feel free to reach out to me at jahurst@hawaii.edu. Mahalo!
Aloha! I am a PhD student in the Tropical Plant and Soil Sciences program at UH Mānoa. I hold a B.S. from the University of Washington and a Certificate in Culinary Arts from Le Cordon Bleu.
My research explores the application of Native American polyculture techniques to Indigenous Polynesian crops, with a focus on Kō (sugarcane). Inspired by the Three Sisters method, I am working with Dr. Lincoln to develop a novel cropping system called “Da Tree Braddahs” and studying how this design impacts soil microbial communities and crop health.
The goal of my work is to support soil regeneration, ecological functionality, improve crop productivity, and promote food sovereignty for Native Hawaiian, Pacific Islander, and other Indigenous communities. Ultimately, I hope to increase access to culturally meaningful, nutritious food that strengthens both land and people. I can be contacted at: leonelf@hawaii.edu.
I’ve always wanted to be an environmental educator, but right out of high school everything was quite new and there wasn’t a perfect path. I took a course in the college of education during my previous Masters program (Environmental Management) and I fell in love with the College of Education. I was an ambassador for the College of Tropical Agriculture and Human Resources (CTAHR) during both my Bachelors and Masters Degrees, during which time I traveled to other islands, represented the college at events, served as the colleges MC for conferences, competitions, & banquets, helped coordinate student life activities, aided in student recruitment, and received leadership training. I am a full time teacher during summer session at Punahou for the PUEO Program serving public school students from Title I Schools.
I am currently pursuing my PhD in 'Aina Based education, focused on agricultural education methods, within the Indigenous Cropping Systems Laboratory. I am also a Research Assistant under Dr. Lincoln, working on a cross-campus collaborative focused on improving student pathways in agriculture within the University of Hawaii.
MSc Students
Building upon the work of Dr. Noa Lincoln, which has provided high-accuracy spatial models of seven agroecological forms across the Hawaiian archipelago, and the work of Mr. Indrajit Gunasekara, who has laid some foundational work for exploring traditional Hawaiian coconut diversity in the islands, I would like to explore the patterns of coconut varieties within isolated areas in an attempt to connect specific varieties to the environmental and/or traditional agroecological patterns.
Aloha! I am a master's student at UH Mānoa studying tropical plant and soil science. I pivoted into agriculture after getting my bachelor's degree, working on farms for several years in North Carolina and on the island of Hawai'i. I am interested in tropical fruit production, agroforestry, and the diversity and conservation of canoe crop varieties.
My research focuses on the shade tolerance of bananas in agroforestry systems, investigating what yields farmers can anticipate based on banana cultivar and level of shade. I am especially interested in the potential of Mai'a Iholena, a Hawaiian banana cultivar with a short crop cycle and dual usage for both fresh eating and cooking. Other Indigenous Cropping Systems Lab projects I am involved in include researching the Pāhala method of kalo cultivation, and a study of the economics of 'ulu agroforestry, surveying and interviewing farmers across the islands with 'ulu incorporated into their agroforestry systems.
Feel free to reach out to me at weiskopf@hawaii.edu if you ever want to chat about bananas, agroforestry, or farming here in Hawai'i!
I'm a Master's student in the CTHAR TPSS Indigenous Cropping Systems Lab researching 'awa nutrient demands and hydroponic growth potential. I currently own and operate several kava ('awa) establishments in the Bay Area and became curious about the nutrient demands and potential capability of growing 'awa in hydroponics. As a root crop with a long growth period, it certainly presents unique challenges to the traditional hydroponics set up. Therefore, my current study focuses on the feasibility of an in-house design for hydroponics that takes these challenges into account.
I am also researching more of the general characteristics of 'awa and trying to shed a little more scientific light on the plethora of ancient wisdom and reverence for this intriguing plant. In my spare time, I enjoy drinking plenty of 'awa coupled with my love of freediving the beautiful coasts here and piloting the short flights between the islands.
I am currently attending The University of Hawaii Hilo in for my Bachelor in Tropical Agroecology. I am a research assistant at the indigenous Cropping Systems Laboratory helping with data collection and photo analysis for a study on Ulu postharvest and processing. Originally from New Mexico I came to Hawaii to complete my undergraduate degree because of the year-round growing season and the chance to learn about and grow a wider variety of plants. I plan to use what I learn in school to contribute to increasing the resilience and sustainability of agriculture and to help conserve the unique biodiversity in Hawaii.
I am a cacao and vanilla farmer with Lydgate Farms on the east side of Kauaʻi, currently working on a master’s degree in CTAHR’s Tropical Plant and Soil Science program at UH Mānoa in Dr. Lincoln’s Indigenous Cropping Systems Lab. After working several years in wildlife biology and conservation in Hawaiʻi, my focus shifted into agriculture and tropical fruit production. I am particularly interested in tropical agroforestry systems, optimizing yields and quality, fermentation, and value-added crops that support Hawaiʻi’s agricultural economy and land use. My research focuses on the effect of fermentation site on flavor development in cacao, controlling for a single clonal variety and growing site, with the goal to better understand how place-based fermentation practices and microbial communities influence cacao quality. In collaboration with PBARC, CTAHR Wailua, and several farms across the state, I hope to unravel our limited understanding of where cacao flavor comes from and create reliable and repeatable fermentation practices for other growers. I also hope, through this project, to promote integrated agroforestry farming principles, stewardship of the ʻāina, and long-term sustainability for Hawaiʻi’s farmers.
Ryland Lubin is a graduate student in the Natural Resources and Environmental Management department at the University of Hawaiʻi at Mānoa, where he works on a PICASC research project focused on restoring dry landscapes through controlling invasive grasses. His work supports efforts to bring back native forests by testing different preparation, planting and maintenance methods in partnership with Native Hawaiian organizations and local land stewards. Through this project, he contributes to work aimed at reducing wildfire risk, improving land health, and supporting reforestation/restoration in the face of climate change.
Aloha! I’m a second-year TPSS master’s student. You might find me working in the ICS Labs experimental greenhouse at the Magoon Research Station in Manoa or hopping between islands for conservation and commercial landscape projects. I am an ISA certified arborist, native plant lover, and landscape architect in training. I completed my undergraduate degree at the UHM School of Architecture before transitioning into CTAHR. The goal of my research journey is to improve the ways in which native plants are brought back into urban spaces. I would like to see healthy urban ecologies supported by expanded native plant palettes and better soil management practices during/after construction.
You can reach out to me by email: scolella@hawaii.edu for ʻulu purchases on Oʻahu or other inquiries.
Undergraduate Researchers and Interns
I am a Global Environmental Science undergrad at the University of Hawaiʻi at Mānoa with a particular interest in large-scale sustainable agriculture implementation and education. Being from Northern Colorado, I grew up surrounded by agriculture which gave me an indispensable perspective on its vitality within a community. I was taught to honor the land and the essential provisions it supplies us with which, paired with my passion for climate change mitigation and environmental conservation, led me to pursue research in sustainable agriculture.
I strongly believe that the key to environmental cohabitation lies in reimplementing Indigenous knowledge. With that being said, my thesis focuses on learning said knowledge directly from Hawaiian planters. I will be conducting both a general survey and individual interviews to identify the co-cropping relationships between culturally significant Hawaiian crops. This information is invaluable in encouraging the further implementation of sustainable agriculture which is an essential step to mitigating climate change. Additionally, it is of the utmost importance to me that such information is made easily accessible to the general public, specifically to Hawaiian farmers.
Born and raised in American Samoa, I am a passionate learner who carries the values of fa'a Samoa into all aspects of my life. My passion for environmental stewardship, sustainable food systems, and the sciences has led me to pursue a B.Sc. in Agricultural Sciences concentrating in Sustainable Cropping Systems Management with minors in Indigenous Studies and Soil Sciences at Cornell University.
My interests lie at the intersection of agroecological research, particularly in sustainable agriculture, and community development with a focus on food security. I am interested in studying crops and processes that demonstrate resilience to changes in climate and exploring their interactions with soil ecosystems.
