BESE Seminar

Instructional faculty candidate lecture: Cross-Talk: How Cells Sense, Signal, and Survive in Diverse Environments

Presenter
Dr. Yusra Siddiqui
Date
20 Apr, 2025
Time
10:00 AM – 11:00 AM

Abstract:
Cell signalling is not only foundational to life—it is exquisitely tuned to the challenges of each organism's environment. This lecture explores molecular communication mechanisms that drive cellular responses in humans, plants, and marine organisms. Building upon foundational molecular biology, we will delve into complex signalling networks, including hormone signalling, calcium-mediated defence, and quorum sensing, with comparative analysis across taxa. Emphasis will be placed on real-world case studies—including Red Sea marine systems, plant immune signalling, and human disease pathways. This talk aims to enhance integrative thinking, drawing connections between molecular signals and their ecological or biomedical outcomes.

Bio:
Dr Yusra Siddiqui is a molecular biologist and educator with a strong interdisciplinary focus at the intersection of cellular signalling, inclusive pedagogy, and curriculum innovation. At the University of Exeter (UK) she teaches across core biological sciences at both undergraduate and postgraduate level, while also serving as Academic Lead for Racial Equality and Inclusion in Biosciences. Yusra’s academic work integrates molecular biology with critical pedagogy, particularly around racial and social justice, decolonization, and equitable learning practices. She brings an international perspective and a deep commitment to student engagement, creating reflective, culturally responsive learning environments. Her research-informed teaching emphasizes the importance of scientific representation and inclusive narratives, particularly in genetics and molecular biology. A regular speaker at conferences and higher education forums, Yusra shares insights on diversifying STEM curricula and empowering students as co-creators in shaping education.
