Biography and Research Information

OverviewAI-generated summary

Maria Almeida's research program focuses on the cellular and molecular mechanisms underlying bone aging and the effects of estrogen deficiency on bone health. Her work investigates the roles of key cellular components and signaling pathways in bone remodeling, particularly concerning osteoblasts and osteoclasts.

Almeida has received significant federal funding to study these processes. Current NIH grants include support for investigating the different consequences of cellular aging in cortical versus cancellous bone, exploring the mechanisms that decrease bone formation with aging, and examining how estrogen antagonizes RANKL signaling in osteoclasts. These projects aim to elucidate pathways that contribute to age-related bone loss and identify potential therapeutic targets.

Her recent publications highlight her contributions to understanding the impact of mitochondrial function, reactive oxygen species, and NAD+ levels on bone cells during aging and estrogen deficiency. She has also published on refining the identification of mesenchymal cell types involved in bone formation and the molecular mechanisms regulating osteoclast gene expression. Almeida's scholarship metrics include an h-index of 54, with over 156 publications and 11,482 citations. She actively collaborates with researchers at the University of Arkansas for Medical Sciences, including Charles A. O’Brien, Elena Ambrogini, Olivia Reyes‐Castro, and Hayley M. Sabol.
