Stephanie de Alcantara Fernandes

Dr. Stephanie de Alcantara Fernandes is a Minerva Fast Track Group Leader at the Max Planck Institute for Biology of Ageing in Cologne, Germany, where she leads research on muscle metabolism and aging. Her laboratory investigates how spatial and functional regulation of mTORC1 signaling influences skeletal muscle health, growth, and regeneration throughout the lifespan, with implications for understanding and promoting healthy aging.

Dr. Fernandes completed her academic training through a distinguished path:

• PhD in Biology (Summa cum laude, with distinction), University of Cologne/Max Planck Institute for Biology of Ageing (2017-2023)
• Master of Science in Genetics, University of São Paulo (2015-2017)
• Bachelor of Science in Biological Sciences, University of São Paulo (2009-2014)
• Exchange year at University of Birmingham, UK (2013)

Her research focuses on skeletal muscle biology, particularly the balance between anabolic and catabolic processes that maintain muscle health. Dr. Fernandes investigates how mTORC1 (mechanistic Target of Rapamycin Complex 1), a central signaling hub, is spatially organized within cells to selectively regulate specific cellular functions in response to different nutrient sources. Her work reveals that mTORC1 is not simply "on or off" but can be finely tuned to control distinct processes in different cellular compartments, particularly in skeletal muscle cells.

A key aspect of her research examines how these regulatory mechanisms change with age, contributing to age-related muscle loss (sarcopenia). By understanding the molecular basis of muscle maintenance and regeneration, her laboratory aims to identify targets for interventions that could promote healthier aging and prevent age-related decline in muscle function.

Analysis of Dr. Fernandes' publication record shows a clear trajectory of increasingly independent research focused on mTORC1 signaling, nutrient sensing, and their roles in aging and muscle biology. Her most recent work demonstrates sophisticated understanding of mTORC1's spatial regulation, revealing how different pools of mTORC1 respond to distinct amino acid sources to control specific cellular processes. This research bridges fundamental cell biology with translational applications for aging-related conditions.

Dr. Fernandes has received numerous prestigious awards recognizing her scientific excellence:

• Minerva Fast Track Fellowship (2025) - Group Leader Position for Outstanding Female Scientists from Max Planck Society
• Graduate School for Biological Sciences (GSfBS) doctoral award for 2023 (2025)
• World Muscle Society Fellowship (2016)
• Cologne Graduate School of Ageing Research fellowship (2017-2020)
• Master's scholarship from São Paulo Research Foundation (2015-2017)
• Science Without Borders Scholarship from Brazilian Council for Scientific and Technological Development (2013)

As a newly appointed Group Leader through the Minerva Fast Track program, Dr. Fernandes is establishing her independent research program with substantial institutional support. Her laboratory combines advanced techniques including high-throughput omics approaches (proteomics, metabolomics), molecular biology, biochemistry, cell biology, and super-resolution microscopy. She utilizes multiple model systems including mouse models, skeletal muscle cell lines, and iPSC-derived skeletal muscle cells to identify evolutionarily conserved mechanisms relevant to human health.

Dr. Fernandes leads the Minerva Fast Track Group at the Max Planck Institute for Biology of Ageing, which focuses specifically on "Muscle metabolism and aging." Her team investigates how selective mTORC1 signaling is coordinated between different skeletal muscle cell types and how it changes with age, with the ultimate goal of understanding how muscle health can be maintained throughout life.
