Celebrating New Publications of East Campus Science Faculty

A Message from Wendy Givoglu, Interim President, East and Winter Park Campuses

Kudos to Andrea Rediske, professor, biology, and Majid Musnavi, part-time faculty, physics, for recently submitting and having articles published in scientific journals.

Andrea’s article titled “Impact of COVID-19 Curricular Shifts on Learning Gains on the Microbiology for Health Sciences Concept Inventory” was published in the April 2021 edition of the Journal of Microbiology and Biology Education. The Microbiology for Health Sciences Concept Inventory (MHSCI) is a validated assessment published in 2017, designed as a pre- and post-test to assess student learning gains in health sciences microbiology. The MHSCI is used by more than 50 colleges in the U.S. and worldwide and is currently being used as part of the Valencia College Assessment of the MCB 2010C course.

The article explores the impact of the COVID-19 pandemic on student outcomes on the MHSCI. Andrea and her co-author Heather Seitz, primary investigator of the MHSCI, compared overall learning gains pre- and post-quarantine to determine the impact of the shift to online learning on student MHSCI scores. Their analysis found that while pre-test scores were slightly lower in the COVID-19 group, there was no difference in student scores when pre- and post-COVID post-tests were compared. The data in this study suggest that student success is statistically similar between face-to-face microbiology courses and courses that shifted online due to the pandemic.

Majid submitted an article in The Journal of Optics Express, “Laser-Plasma Coupling for Enhance Ablation of GaAs with Combined Femtosecond and Nanosecond Pulses.” The article looks at the rapid development of femtosecond lasers over the last decade that has opened a wide range of new applications, especially, in industry, material science, medicine and remote sensing. One important physical effect is material removal or laser ablation by femtosecond pulses which can be used for the deposition of thin films, the creation of new materials, micro-machining and plasma-shock production. Particularly, laser filamentation can deliver laser intensities sufficient to ablate materials to kilometer-range distances. In this work, the role of laser-plasma interactions in the enhancement of ablation by different combinations of femtosecond and nanosecond laser pulses is investigated.

Last year, Majid also submitted an article in Science Direct regarding Calculation of the extreme-ultraviolet radiation conversion efficiency for a laser-produced tin plasma source.”

“It is amazing to have faculty still deeply involved in research,” said Dean of Science Jen Snyder. “It enhances their practice and elevates the classroom experience for their students. Students always enjoy hearing about faculty research interests, because it makes the professor and the science more accessible.”
