Principal Investigator

Claire Acevedo, PhD

Biography: Claire Acevedo’s background and expertise is at the interface between mechanical behavior of materials, biology, and experimental high-energy x-ray physics. Her research goals are directed toward understanding the mechanisms of deformation, fracture, and the biological responses at multiple length-scales (from molecular to macroscales). During her PhD study at the Swiss Federal Institute of Technology Lausanne (EPFL), she worked on the influence of residual strains on fatigue resistance of metallic connections using high-energy neutron diffraction instruments. Following her PhD, her postdoc studies at UC Berkeley, UC San Francisco, and the Lawrence Berkeley National Lab centered upon the hierarchical organization and deformations of collagen and mineral nanocomponents to create specific macroscale mechanical properties and resistance to fracture. In biomechanics, she is developing an understanding of the role that osteocyte-mediated remodeling plays in affecting bone quality and how it can be degraded with bone fragility diseases.

Research: My research focuses on fatigue and fracture mechanics, biomechanics, bone, tissue engineering, synchrotron based techniques, multi-scale approaches and biomaterials. (Google Scholar)
Teaching: Introduction to Continuum Mechanics (ME EN 5530/6530), Statics (ME EN 2010), Strength of Materials (ME EN 3300)

Graduate Students

James Rosenberg

James is a Ph.D student studying fragility diseases, fatigue life, and mechanical properties of bone. He graduated from the University of California Merced with BS in Material Science and Engineering with an emphasis in Nanotechnology. He interned for two summers at NASA Langley where he worked on boron nitride nanotube composite materials. His other interests include photography, biking, skiing, and cooking.

William Woolley

William Woolley graduated back in France with a Master of “Training, Biology, Nutrition, and Health” and then he obtained a second master’s degree in “Bioengineering of Tissue and Implants”. He joined the University of Utah in 2019, first as an intern, then stayed to pursue his Ph.D. in Mechanical Engineering. His research interest is assessing the effect of bone quality on the mechanical properties of bone. Specifically, he is working on the effect of high fracture risk diseases, such as diabetes, on collagen. In his spare time, William enjoys the outdoors and many different sports such as biking, skiing, and tennis.

Yoshihiro Obata 

Yoshihiro (Yoshi) Obata is a Mechanical Engineering Ph.D. student who joined the Fracture and Fatigue of Skeletal Tissues Lab in 2019. He graduated from North Carolina State University with a BS in Aerospace Engineering. During this time, Yoshi interned at NASA Langley Research Center where he developed a passion for  fracture mechanics research. At the U, he works primarily with synchrotron radiation micro-computed tomography (SRuCT) datasets to understand how changes in bone quality and bone fragility are related. His other interests include climbing, running, biking, and listening to music.

Michael Sieverts

Mike is studying bone through image data such as μCT and microscopy. After graduating with a BS in Biological Engineering from Utah State University, Mike went on to work in biotechnology where he gained experience with Raman spectrometry, computed tomography, and data science. Now pursuing a PhD at the U, he is interested in using bone imaging techniques, data science, and machine learning to understand how bone is damaged by disease at the micro- and nanoscale. Outside of research, Mike likes climbing, biking, snowboarding/skiing, and spending time with family.
