Matt recently attended the 52nd annual meeting of the American Aging Association (AGE) in Madison, Wisconsin and met with several people doing fascinating work in the longevity field.

One of these was Berenice Benayoun, an Associate Professor (recently tenured!) of Gerontology, Biological Sciences, Biochemistry, and Molecular Medicine at the University of Southern California Leonard Davis School of Gerontology. Berenice delivered the keynote speech at the 2024 AGE meeting, where she received the 2024 Vincent Cristofalo Rising Star Award in Aging Research. Her research focuses on the influence of genomic regulation mechanisms, environmental stimuli, and factors such as biological sex on vertebrate aging and healthspan. Berenice was named a 2020 Pew Biomedical Scholar and a 2021 Nathan Shock new Investigator, and also received the 2019 Rosalind Franklin Young Investigator Award in Mammalian Genetics, an American Federation of Aging Research Junior Faculty Award, and a Global Consortium for Reproductive Longevity and Equality GCRLE Junior Scholar Award.

In this episode, Matt and Berenice chat about the ovaries as a vehicle for understanding aging, the difference between estropause and menopause, and the controversies associated with hormone replacement therapy, and how Berenice made her way into the lab of her dreams. They also discuss the African turquoise killifish, a new vertebrate model organism for longevity research, and address a couple of questions about research we have recently featured on this podcast (how pregnancy affects aging, and sex-specific differences in the effects of estradiol on mouse aging).

Hi, I'm Matt Kaeberlein. I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.

On this podcast I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these episodes helpful!
