Non Technical Summary
Since 2019 when "Being Recognized as a Research University" was set to be the top initiative strategy of the strategic plan of the University of Guam, more and more undergraduate students are requesting research experience before they graduate. More than one and a half year of online learning restricted students' opportunities to experience essential hands-on experimental learning because of the COVID-19 pandemic. The Division of Natural Sciences of the UOG College of Natural and Applied Sciences lacks sufficient laboratory space and funding to support undergraduate research opportunities. To satisfy the increasing demands for undergraduate research experience at UOG, we proposed to develop multidisciplinary research opportunities for undergraduates to engage in research at UOG. Specifically, we proposed 1) to develop a new high-division research course CH490 for undergraduates to gain research experience with course credits at UOG during academic semesters, and 2) to offer paid research internship opportunities for undergraduates to gain research experience with stipends at UOG during summer break. Participating students will work on individual research projects under the close guidance of faculty. The multidisciplinary research will primarily focus on natural product research which involves isolation, purification, and identification of bioactive organic compounds from local plant extracts instructed by the project PD. The biological properties of isolated compounds (such as Antioxidant Capacity (AC), Total Phenolic Content (TPC) and their relationship) will be analyzed by participating students through collaboration among faculty members in agriculture and food sciences. Our target local plants include but are not limited to local Calamansi peels, local mango leaves, and local guava leaves, etc. The students' research activities include conducting a literature survey, formulation of a hypothesis, designing and conducting experimentation, data collection and data analysis, and presentation of results (in oral PPT and /or poster). Each participating student will be required to write a full research project report after completion of their projects. Once we obtain sufficient publishable data, we will prepare a manuscript for publication with student researcher co-authorship.The project will train students to gain advanced knowledge, techniques, and experience which motivate them to pursue study and research in the food, agriculture, natural sources, and human sciences (FANH), and will become part of a competent and qualified workforce to serve FANH in future; the project will promote and strengthen the ability of UOG to carry out research and education in chemistry, food and agriculture sciences; the project will also advance educational equity by increasing participation of underrepresented students at UOG who are unable to participate in mainland REU because they need to take care of their family members or because of other reasons that prevent them from leaving Guam.

Goals / Objectives
To satisfy the increasing demands for undergraduate research experience at the University of Guam, we proposed to develop multidisciplinary research opportunities for undergraduates at UOG. The objectives of the project are:to develop and offer a new high-division research course for undergraduates at UOG during academic semesters,to offer research internship opportunities with stipends for undergraduates at UOG during summer break.Within the project duration, eight participating students will be supported to work on individual research projects under the close guidance of faculty. Two senior undergraduates will be hired and trained to serve as research assistants for this project. The multidisciplinary research will primarily focus on natural product research which involves isolation, purification, and identification of bioactive organic compounds from local plant extracts instructed by the project PD and analysis of biological properties and beneficial and adverse effects of isolated compounds with the participation of other CNAS faculty. Our target local plants include but are not limited to local Calamansi peels, local mango leaves, and local guava leaves, etc. The project will not only train future graduates to gain advanced knowledge, techniques, and experience to ensure a competent and qualified workforce to serve the FANH sciences in future but will promote and strengthen the ability of UOG to carry out research and education in the food and agriculture sciences. The project will also advance student recruitment, retention, and educational equity, in alignment with the goals of the RIIA program.
Project Methods
The proposed Special Project CH490 (4-6 credit hrs.) will be a course for individual students on individual research projects. It will take more than one semester to get the new course approved. In addition, the experimental requirements for this research course will need advanced planning and preparation. Students planning to take this course must inform the instructor at least one semester prior to taking this course. This course CH490 can serve as an upper division elective course for undergraduates Chemistry majors. It can also be taken to fulfill the elective requirement for graduate programs in Biology, Environmental Science, Sustainable Agriculture Food and Natural Resources.(Prerequisites are CH310A, CH311, and consent of instructor.)Students will undertake a project on the selected topic under the close guidance of faculty (PD and co-PDs). Participating students will get thorough research training in multidisciplinary research in chemistry, agriculture, and food sciences. The research activities include conducting a literature survey, formulation of a hypothesis, writing of project proposal, designing, and conducting experimentation, data collection and data analysis, and presentation of results. Students will be required to write a full research project report after completion of their projects. Once we obtain sufficient research data, students will present their data (in oral PPT and /or poster) at a seminar or conference, and we will prepare a manuscript for publication with student researcher co-authorship.Management PlanYear 1 & 2Objective 1) develop and offer a new upper-division research course SPECIAL PROJECT CH490 for undergraduates at UOG during academic semesters (4-6 credit hours).A.

Outputs
Target Audience:The taregt audience includes undergraduates at the Univeristy of Guam majoring in STEM fields and the local co9mmunity that will receive the benefit of the student-centered research. Changes/Problems:PD (Wu) was awarded one-year sabbatical leave by UOG during AY2024-2025 and she did academic/research visiting outside of UOG during her sabbatical leave. To complete all proposed objectives and activities,PD (Wu) applied for one-year no-cost extension of the project in 2025 due toher one-year sabbatical leave during AY2024-2025.The one-year no-cost extension application has been kindly approved by USDA NIFA to allow us to complete all remaining objectives and activities. Accordingly, the new ending date of the project will be August 31, 2027, the second-round internship will be re-scheduled in Summer 2026 and the second-round research course CH490 in AY2026-2027. What opportunities for training and professional development has the project provided? Nothing Reported How have the results been disseminated to communities of interest?The research results have been presented by students and/or faculty at local, regional, national, or international conferences. Some outputs of the project (products, results, and impact) have been published in peer reviewed conferece proceedings with student coauthorship.

Underlined names are UOG undergraduate students involved in the RIIA project.) What do you plan to do during the next reporting period to accomplish the goals?We will continue to complete the remaining part of the project, specifically, 1. We will continue to offer a second-round research internship program in Summer 2026 to support another two UOG undergraduate students to conduct multidisciplinary research. 2. We will continue to offer a second-round research course Special Project CH490 to support another two UOG undergraduate students to conduct multidisciplinary research during AY2026-2027. We will hire and train one more UOG undergraduate RA to assist the remaining portion of the RIIA project.

Impacts
What was accomplished under these goals? PD (Wu) was on one-year sabbatical leave during AY2024-2025 and did academic/research visiting outside of UOG during her one-year sabbatical leave. So far, the following objectives have been accomplished: Objective 1:to develop and offer a new high-division research course for undergraduates at UOG during academic semesters. As proposed, we successfully developed and offered a new upper-division research course SPECIAL PROJECT CH490 (4 credit hours) for the first time to support two UOG undergraduate students to conduct multidisciplinary research in Spring 2024 semester. Objective 2: to offer research internship opportunities with stipends for undergraduates at UOG during summer break. As proposed, we successfully offered a research internship program for the first time to support two UOG undergraduate interns to conduct multidisciplinary natural product research in Summer 2024, during which one UOG Junior undergraduate was hired and trained as a RA to assist our RIIA project. To our delight,we have supported five UOG undergraduate students to conduct multidisciplinary research through the first-round research course CH490 and the first-round research internship during AY2023-2024, which means wehaveaccomplished half of the objectives in which eight participating UOG undergraduate students will be supported to work on individual research projects under the close guidance of faculty and two senior UOG undergraduates will be hired and trained to serve as research assistants for this project.We will continue to support additional five UOG undergraduate students to conduct multidisciplinary research by offering a second-round research internship in Summer 2026 and offering a second-round research course CH490during AY2026-2027.

    Progress 09/01/23 to 08/31/24

    Outputs
    Target Audience:The targeted audiences of the project are primarily undergraduates of UOG who major in chemistry, agriculture and life sciences, and other chemistry related STEM sciences. During the first year (09/01/2023-08/31/2024) of the project, four UOG undergraduates were supported to work on individual multidisciplinary research projects under the close guidance of faculty (PD and co-PDs). One Junior undergraduate was hired and trained to serve as RA for the project. One high school senior intern (female) from Harvest Christian Academy in Guam was also supported to join our 2024 summer internship. The participating undergraduates include three female undergraduates and one male undergraduate. In addition, one undergraduate is a first-generation college student. The participating undergraduates came from diverse majors: one majored in Agriculture & life Sciences-Human Nutrition & Food Science, two majored in Chemistry and Biology Dual, and one majored in Integrative Biology. The project not only trained future graduates to gain advanced knowledge, techniques, and experience to ensure a competent and qualified workforce to serve the FANH sciences in future, but will advance student recruitment, retention, and educational equity at UOG.All participants were very satisfied with the research training they received. Changes/Problems:As a tenured professor at UOG, I am currently on sabbatical leave and will stay off-island during my sabbatical leave (Fall 2024 -Spring 2025) to enhance my career goals of my personal growth and professional development. Thus, during my sabbatical leave, we couldn't conduct the wet lab research of the RIIA project at UOG. To avoid significant deviations from the research schedule or goals because of my sabbatical leave (Fall 2024-Spring 2025), I adjusted the timetable of the objectives as follows. The first-round research course CH490, which was originally scheduled in the semester during Fall 2024-Spring 2025, wassuccessfully offered and completed in Spring 2024 semester because PD will be on sabbatical leave during F2024-Spring 2025. We have also successfully offered and completed our first-round summer internship in 2024 summer break. The second-round summer internship, which was originally scheduled in Summer 2025, will be planned to re-schedule in Summer 2026 because PD will be on sabbatical leave during F2024-Spring 2025. It will be better to arrange the second-round summer internship in Summer 2026 rather than Summer 2025 because it will take at least half a year in advance for PD to prepare for the second-round summer internship on campus. What opportunities for training and professional development has the project provided?Each participating undergraduate student undertook an individual multidisciplinary research project on the selected topic under the close guidance of faculty (PD and co-PDs). They all involved the following research activities: conducting a literature survey, formulation of a hypothesis, writing of project proposal, designing and conducting experimentation, data collection and data analysis, and presentation of results. Each participating undergraduate submitted a full research project report and presented their data (in oral PPT) after completion of their projects. Participating students received thorough research training in multidisciplinary research in chemistry and in biological property tests. Experimental learning training in chemistry included, but were not limited to, refluxing extraction and maceration extraction with different solvent for different time, different filtration methods, centrifuge separation, rotary evaporation, and freeze drying. Biotesting training included TPC Folin-Ciocalteu (FC) assay and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) Free radical Scavenging assay. All participants were very satisfied with the research training they received. How have the results been disseminated to communities of interest?The research results have been presented by students and/or faculty at local, regional, national, or international conferences. The project outputs (products, results, and impact) will be prepared to publish in peer reviewed journals with student co-authorship.

What do you plan to do during the next reporting period to accomplish the goals?As a tenured professor of the UOG, I am currently on sabbatical leave and will stay off-island during my sabbatical leave (Fall 2024 -Spring 2025) to enhance my career goals of my personal growth and professional development. Thus, during my sabbatical leave, I couldn't supervise trainees to conduct the wet lab research of the RIIA project at UOG, but I will review student research results and prepare for oral/poster presentation at a seminar or conference and prepare manuscripts for publication. Our stated three-year goals have not been fully met yet. During the first year, we have supported four participating students to work on individual multidisciplinary research projects under the close guidance of faculty (PD and co-PDs) and one undergraduate was hired and trained to serve as a research assistant for this project. During the remaining time of the project, we still need to train four more undergraduates to work on multidisciplinary research project and hire one more undergraduate RA to assistant the project. Therefore, I together with co-PDs will offer an updated SPECIAL PROJECT CH490 during an academic semester (spring 2026) and will offer paid multidisciplinary research internship opportunities for undergraduates at UOG during summer break ($4,000/intern, 8 weeks, 2026 summer) after I return to Guam from my sabbatical leave. I will update the research course CH490 and 2024 summer internship based on our successful research course CH490 (Spring 2024) and 2024 summer internship. I will also incorporate what I learned about natural product research from my academic visiting during my sabbatical leave. I believe my academic visiting during my sabbatical leave will further enhance the quality of our next research course CH490 and summer internship.

    Impacts
    What was accomplished under these goals? To satisfy the increasing demands for undergraduate research experience at the University of Guam, we developed multidisciplinary research opportunities for undergraduates at UOG. The following objectives have been accomplished: to develop and offer a new high-division research course for undergraduates at UOG during academic semesters. As proposed, we successively developed and offered a new upper-division research course SPECIAL PROJECT CH490 for undergraduates at UOG in Spring 2024 semester (4 credit hours). Two UOG under graduates were enrolled in the research course CH490 (Spring 2024). to offer research internship opportunities with stipends for undergraduates at UOG during summer break. As proposed, we successively offered paid multidisciplinary research internship opportunities for undergraduates at UOG during summer 2024 ($4,000/intern, 8 weeks). Two UOG undergraduates participated the 2024 summer internship and one UOG undergraduate was hired as an RA to assistant the projects. During the first year (09/01/2023-08/31/2024) of the three-year project (09/01/2023-08/31/2026), four UOG undergraduates were supported to work on individual multidisciplinary research projects under the close guidance of faculty (PD and co-PDs) and one Junior undergraduate was hired and trained to serve as RA for the project. We have successively accomplished the first-year objectives, half of the three-year objectives in which eight undergraduates will be supported and two undergraudate RAs will be hired and trained under the RIIA project). Notably, both research course Special Project CH490 (Spring 2024) and 2024 summer research internship offered multidisciplinary research project opportunities for participating UOG undergraduates. Each participating student undertook an individual project on the selected topic under the close guidance of faculty (PD and co-PDs). The four participating UOG undergraduates investigated the Antioxidant Activity and Total Phenolic Contents (TPC) of four local medicinal plants: Microsorum scolopendria, Artocarpus altilis, Antigonon leptopus and Phyllanthus amarus. The effect of different extraction methods on their antioxidant activity and TPC were also investigated. Participating students received thorough research training in multidisciplinary research in chemistry, agriculture, and food sciences. All participants were very satisfied with the research training they received. The project has increased the number of students who gain knowledge, skills, and research experience in chemistry, agriculture, and food sciences; increased the number of underrepresented minorities/women who will gain research experience in chemistry, agriculture, and life sciences; will increase the number of students' presentation and research reports in chemistry, agriculture, and food sciences; and will increase the number of students who pursue graduate study in chemistry, agriculture, and food sciences and related STEM after graduation. The project has trained future graduates to gain advanced knowledge, techniques, and experience to ensure a competent and qualified workforce to serve the FANH sciences in future, has enhanced educational equity of UOG by increasing the number of under-represented minorities/women participating in research, will strengthen student recruitment and retention programs of UOG by increasing the number and diversity of students who will involve in research, and will broaden faculty research area by multidisciplinary collaboration.
