CBS Welcomes Four New Faculty With Wide-Ranging Expertise

New faculty bring expertise in plant–environment interactions, inclusive STEM pedagogy, microbiota research, and archaeal biology

The college is very pleased to have welcomed four new faculty during the 2025 calendar year. Joining the Departments of Microbiology and Molecular Genetics, Evolution and Ecology, and Molecular and Cellular Biology, each new faculty member adds expertise and breadth to the college’s research and teaching portfolio.

“The college’s newest faculty, who are both researchers and teachers, are poised to continue our legacy of excellence in foundational life sciences exploration, as well as exceptional student teaching and mentorship,” said Mark Winey, dean of the College of Biological Sciences. “I am thrilled to welcome them to campus.”

The new faculty began at varying times in the 2025 calendar year, with two arriving during the 2024-25 academic year (July 1, 2024 to June 30, 2025), and two arriving in the 2025-26 academic year (July 1, 2025 to June 30, 2026).

With expertise ranging from plant-environment interactions and inclusive STEM education, to archaeal cell biology and host–microbiota–pathogen dynamics, they will make significant contributions to the excellence and scientific breadth of the college.

Angelica Guercio
Assistant Professor of Teaching
Department of Molecular and Cellular Biology

Angelica Guercio’s work centers on biology education and inclusive pedagogy, with the goal of fostering scientific literacy, identity, and success for students in biochemistry and molecular biology. Her research examines how evidence-based teaching practices help students not only master course content but also think, read, write, and engage like scientists. She incorporates assignments such as Scientist Spotlights and reflective dialogues that connect students with the lives and work of established scientists, building confidence and a sense of belonging in STEM. Guercio also investigates how course structures and assessment strategies shape transfer student outcomes in large lecture classes, testing approaches such as diagnostic modules and flexible assessments to reduce barriers and improve equity. Her teaching philosophy emphasizes growth mindset, inquiry-driven learning, and individualized mentorship, ensuring that students feel supported while developing autonomy as scientists. By integrating inclusive pedagogy with authentic classroom experiences, Guercio seeks to create transformative learning environments that cultivate curiosity, resilience, and long-term engagement in science.
