Doctoral Student
UNO Biomechanics
Alli Grunkemeyer is a PhD candidate in Biomechanics at the University of Nebraska at Omaha, where her research focuses on improving sensorimotor function in individuals with limb loss and age-related sensory decline. With a background in biomedical engineering, her work integrates haptic perception, dynamic movement analysis, and sensory augmentation to address challenges in rehabilitation.
Her current research investigates how low-level vibrotactile noise—delivered below the threshold of conscious awareness—can influence the perception of object heaviness during functional tasks. She explores how both the structure of the noise and the dynamics of exploratory movement affect perceptual accuracy, with implications for designing sensory-enhancing feedback systems for prosthesis users and older adults. Alli’s work draws on nonlinear time series analysis, ARFIMA modeling, multi-level statistical modeling, and high-resolution motion capture to better understand the dynamics of sensorimotor integration.
She has led multiple funded projects focused on perceptual rehabilitation and is committed to translating laboratory findings into real-world clinical applications. In addition to her research, Alli actively supports inclusive science education and advocates for increasing representation in STEM and healthcare fields.
