About Gunes Uzer

Bio

Dr. Gunes Uzer is an Associate Professor in the Department of Mechanical and Biomedical Engineering at Boise State University. Dr. Uzer’s studies have covered a broad range of topics, including advanced material characterization, experimental photometry, finite element modeling, as well as cell and animal models. Since 2016, he is the director of the Mechanical Adaptations
Laboratory leading a multidisciplinary research program on the nuclear mechanobiology.

Studies in Mechanical Adaptations Laboratory are directed towards understanding how changes in tissue mechanical environment in relation to exercise, injury, aging and disuse regulate structural adaptations in cells cytoskeleton and nucleus to control signaling and eventually fate decisions in stem cells.

Research

Research in Mechanical Adaptations Laboratory employs both molecular biology and engineering principles to experimental and computational approaches with a goal of understanding how mechanical forces regulate cell structure and function.

Current Projects:

Nuclear Envelope Mechanobiology: Focusing on the nucleo-cytoskeletal connectivity provided by LINC complexes, we investigate how physical activity and external mechanical signals regulate the stem cell mechanosignaling during aging. This study is funded by NIH.

Mechanical Regulation of Nuclear Mechanics and Gene Expression: By utilizing computational methods and optical metrology, we quantify how external mechanical signals regulate nuclear structure and gene expression in live cells. This study is funded by NSF.

Bone Marrow Analogs and Microgravity: We examine how decreases in age-associated bone volume contribute to decreased osteogenic capacity of stem cells in a bone marrow analog tissue under mechanical challenge. Microgravity conditions of International Space Station is used simulate the aging process of stem cells and permit direct analysis of biomechanics in real-time. This study is funded by AR3T, NIH, NSF, ISS and NASA.
