What inspired you to pursue aging research?
The striking disparity between estradiol's robust neuromodulatory effects in the young brain versus its diminished efficacy during aging sparked my scientific interest early during my PhD training. I was drawn to understanding this age-related shift and the molecular mechanisms underlying the brain's declining hormonal responsiveness with age. The cognitive changes that accompany midlife hormonal transitions, particularly in perimenopausal women, underscore the urgent need to understand how neuroendocrine regulation evolves over the lifespan. This research felt especially meaningful because it bridges fundamental neurobiology with the potential to develop targeted interventions that could preserve cognitive health during our most vulnerable years.
In your view, what does AFAR mean to the field, and what does it mean, for you, to receive an AFAR grant now?
AFAR represents a vital catalyst for the field of aging research, providing crucial support for innovative lines of investigation that might otherwise remain unexplored due to current funding and resource limitations. Throughout my career, I've been deeply interested in translating our knowledge of estradiol's beneficial effects in the young brain to understand and potentially remedy age-related cognitive decline, but until now have lacked the resources to pursue this important research direction. The AFAR Junior Faculty grant is truly transformative for my laboratory, as it provides the essential funding to bridge this knowledge gap and investigate how neuroendocrine mechanisms change across the lifespan. I am honored to receive this opportunity, as it will enable me to tackle fundamental questions about hormonal neuroprotection during aging that could ultimately inform therapeutic strategies for preserving cognitive health in our rapidly aging population.
What is exciting about your research’s potential impact?
The most exciting aspect of this research is its potential to revolutionize how we approach cognitive aging by identifying cell-type-specific molecular mechanisms that could be therapeutically targeted. By understanding precisely how estradiol's neuroprotective pathways become dysregulated during aging, we can move beyond simply observing age-related cognitive decline to actively intervening at the cellular level. Our findings could inform the development of precision therapies that restore hormonal responsiveness in aging brains, potentially offering new hope for millions facing age-related memory loss. Perhaps most compelling is the prospect that by harnessing the brain's own capacity for local estradiol synthesis, we might develop interventions that don't rely on systemic hormone replacement but instead optimize the brain's endogenous neuroprotective mechanisms.
How would you describe your research to a non-scientist?
Research in my lab focuses on estradiol, a sex-steroid hormone that plays a crucial role in keeping brain cells healthy and supporting strong memory formation in young adults. As we age, two problems emerge: our bodies naturally begin producing less estradiol, and our brain cells become less responsive to hormone levels that remain in circulation. Our research aims to understand the molecular alterations that accompany these age-related changes in different cell types within the hippocampus, a brain region critical for long-term memory storage. By using state-of-the-art approaches to better define cell-type-specific alterations that occur during aging, we aim to develop targeted intervention strategies to either restore adequate hormone signaling or improve cellular responsiveness locally in the brain. Our ultimate goal is to help people maintain sharper cognitive function as they age by targeting these specific biological mechanisms.
