Body Composition Research

These studies look at fat, lean, and bone tissue to quantify how aspects of body shape exhibit risk of diseases such as cancers and obesity. We also study how the development and a person’s environment may affect their body. Click the links to learn more.

Ongoing Projects

  • Shape Up! Studies

    Shape Up! Studies explore and develop ways to measure health and body composition from 2D and 3D images, which can then provide useful and detailed information about various health and wellness risks. The research relies on information gathered from subjects. If you’d like to participate, visit the site to learn more!

  • Deep Learning and Total Body DXA Scans (The TBDXA.I. Project)

    Deep Learning and Total Body DXA Scans (The TBDXA.I. Project)

    Overview Deep Learning trains neural networks on large datasets, including images, to generate algorithms that predict endpoints. Total Body DXA scans contain digital information about body composition (fat, bone, lean… Read More »Deep Learning and Total Body DXA Scans (The TBDXA.I. Project)


  • Space-Feasible Body Composition and Body Shape Analysis for Long Duration Missions (Astro3DO)

    Space-Feasible Body Composition and Body Shape Analysis for Long Duration Missions (Astro3DO)

    Overview Long-duration space flights and extraterrestrial colonizing magnify physiology challenges for the voyagers involved, including debilitating loss of muscle and bone mass. The musculoskeletal changes are primarily from acclimation to… Read More »Space-Feasible Body Composition and Body Shape Analysis for Long Duration Missions (Astro3DO)


Completed Projects

  • Samsung Bioimpedance System Evaluation Study

    Samsung Bioimpedance System Evaluation Study

    Overview Bioimpedance analysis systems are rapidly evolving and are now increasingly being used in research, clinical, and home settings (1). The novel Samsung BIA devices operate through a wrist-worn watch… Read More »Samsung Bioimpedance System Evaluation Study


  • Da Kine Body Composition Study

    Da Kine Body Composition Study

    Overview Hydration status and total body water (TBW) in humans may vary in special populations such as athletes and age groups. This variability may lead to inaccurate body composition measurements… Read More »Da Kine Body Composition Study
