Development of a virtual poverty simulation
Date presented 2021
Student Scholar Symposium & Faculty Research Showcase, 2021, University of West Florida, Pensacola, Florida
The Poverty Simulation is a 3-hour interactive wortDue to the restriction of in-person event, the Honor Core students converted the in-person experience to a virtual platform with assignments that included creating online webpages. constructing online links and materials. developing operational instructions, designing marketing materials and conducting practice sessions with faculty members.
Each team member took the lead for a community agency. The student was in charge of the activities and transactions for the agency, interacting with the participants. ensuring a successful process. and training a faculty member partner.
The team showcased their project by leading the virtual poverty simulation they developed for over 40 of their Honors Core classmates

Taking Responsibility to Create a Trauma and Social Justice-Informed Workforce
Published 2021
Journal of higher education theory and practice, 21, 9, 71 - 81
This conceptual paper describes the efforts to address curriculum deficits related to the preparation of graduates across multiple service fields for their work in high-poverty communities. Faculty members from various programs jointly facilitated a high-impact simulation designed to ascertain its impact on students' perceptions and personal biases toward disadvantaged community members. This mixed methods study used Yun and Weaver's (2010) Short Form of the Attitude Toward Poverty Scale, as well as focus groups. Quantitative data indicated that participants held more positive attitudes towards individuals struggling with poverty after completing the simulation. The overarching themes concerning college students' attitudes about poverty indicated paradigm shifts in their personal thinking and professional behavior in the workforce, as well as empathy regarding the cycle of poverty and the extremely hard decisions that are necessary when experiencing poverty. These findings are important for facilitating learning about the social injustices that can ensue from poverty. The study comes at a time of a pandemic when online learning is at its height and poverty is intensifying.

Endurance exercise attenuates doxorubicin-induced cardiotoxicity
Published 2020
Journal of Science in Sport and Exercise, 52, 25 - 36
Purpose: Endurance exercise (EXE) preconditioning before DOX treatment confers cardioprotection; however, whether EXE postconditioning (i.e., EXE intervention after the completion of DOX treatment) is cardioprotective remains unknown. Thus, the aim of the present study was to investigate if EXE postconditioning provides cardioprotection by testing the hypothesis that EXE-autophagy upregulation and NADPH oxidase 2 (NOX2) downregulation would be linked to cardioprotection against DOX-induced cardiotoxicity.
Methods: C57BL/6 male mice were assigned into three groups: control (CON, n = 10), doxorubicin (DOX, n = 10), and doxorubicin + endurance exercise (DOX + EXE, n = 10). Animals assigned to DOX and DOX + EXE groups were intraperitoneally injected with DOX (5 mg·kg each week for 4 wk). Forty-eight hours after the last DOX treatment, the mice assigned to DOX + EXE performed EXE on a motorized treadmill at a speed of 13-15 m·min for 60 min·d for 4 wk.
Results: EXE prevented DOX-induced apoptosis and mitigated tissue damages. Although DOX did not modulate auto/mitophagy, EXE significantly enhanced its flux (increased LC3-II levels, reduced p62 levels, and increased autophagosomes with mitochondria) along with increased mitochondrial fission (DRP1) and reduced fusion markers (OPA1 and MFN2). Interestingly, EXE-induced autophagy against DOX occurred in the absence of alterations of autophagy inducer AMPK or autophagy inhibitor mTOR signaling. EXE prohibited DOX-induced oxidative damages by suppressing NOX2 levels but without modulating other key antioxidant enzymes including MnSOD, CuZnSOD, catalase, and GPX1/2.
Conclusion: Our data provide novel findings that EXE-induced auto/mitophagy promotion and NOX2 downregulation are linked to cardioprotection against DOX-induced cardiotoxicity. Importantly, our study shows that EXE postconditioning intervention is effective and efficacious to prevent DOX-induced cardiac injuries.
