Research Scientists

Ryan Downey

Ryan earned his PhD in Mechanical Engineering from the University of Florida in 2015 where his work focused on nonlinear control and functional electrical stimulation. He later joined the Stroke Recovery Research Center at the Medical University of South Carolina where he gained clinical experience and was exposed to EEG (electroencephalography). Inspired to one day create brain computer interfaces for people with physical disabilities, Ryan returned to the University of Florida to join the Human Neuromechanics Lab where his goal is to become an expert in mobile brain imaging. Ryan’s work currently focuses on 1) developing new signal processing algorithms that enable us to examine brain activity during whole body movement without the detrimental effects of motion artifacts and 2) understanding and predicting mobility decline in older adults with mobile brain imaging.

PostDoctoral Fellows

Chang Liu

Chang received her Ph.D. and BS in Biomedical Engineering at the University of Southern California. She previously worked with Dr. James Finley in the Locomotor Control Lab. Her research focused on understanding the reactive stabilization strategies during walking in people with neurological disorders and non-disabled populations. Her current research is to investigate the brain dynamics during locomotion and balance challenging tasks using the mobile EEG setting. She hopes that eventually her work could contribute to improving mobility for aging population and people with neurological disorders in the community. (Email) (LinkedIn) (Google Scholar)


Erika Pliner

Erika received her PhD in Bioengineering at the University of Pittsburgh, and her B.S. in Mechanical Engineering and M.S. in Engineering at the University of Wisconsin-Milwaukee. Her previous research identified individual, environmental and biomechanical factors that contribute to ladder falls, translating to improved safety guidelines and training programs to reduce ladder fall injuries. She has also contributed to the body of Scholarship of Teaching and Learning, using pedagogical techniques to increase student engagement in biomechanics for students underrepresented in the STEM fields. Erika will advance her knowledge of aging and mobility in the HNL by quantifying the efficacy of balance training paradigms from neuromechanical and biomechanical responses.

Lab Staff

Ryland Swearinger (Lab Manager)

Ryland received his BEng and MSc in Biomedical Engineering from the University of Strathclyde. His undergraduate and graduate thesis work focused on biomechanics testing, where he worked to modernize a short pylon transducer for use in trans-tibial prosthetic legs.  After graduating he worked in forensic biomechanics at the National Biomechanics Institute. In October 2021 he began working as the Lab Manager, where he organizes and manages the entire lab, analyzes data, and helps students whenever needed. (Email)




PH.D. Students

Walter “Sebastian” Barrutia

Sebastian was born and raised in Peru and moved to the United States when he was in high school. Since then, he has lived in Texas, New York, and now in Florida. He received a Bachelor of Science in Biomedical and Mechanical Engineering from Rensselaer Polytechnic Institute in 2019.  He is currently a second-year PhD student. His current research interests include the development of novel lower-limb exoskeleton designs to aid walking in healthy and disabled populations. His favorite hobbies are practicing taekwondo and kayaking.​ (Email)




Rachel Hybart

Rachel graduated from Mississippi State in 2017 with her B.S. in Agricultural and Biological Engineering with a concentration in Biomedical Engineering. Since joining the Human Neuromechanics Lab in 2017, she has been studying neural adaptation to lower limb, robotic exoskeletons. She is currently president of UF’s American Society for Biomechanics student chapter. She is also active in the BME Graduate Student Council. She hopes to take her research and leadership experiences into industry post-graduation. (Email) (LinkedIn) (Science Twitter)



Noelle Jacobsen

Noelle graduated from Lehigh University in 2018 with a B.S. in Bioengineering and minors in Electrical Engineering and Business. As an undergraduate researcher, Noelle studied mechanical control of neural stem cell division. She is now studying brain dynamics contributing to locomotor adaptation as she pursues her PhD in Biomedical Engineering. After gaining an expertise in non-invasive mobile brain imaging during her doctorate, Noelle wants to expand her skillset to include invasive techniques for neuroimaging and stimulation. Noelle’s career goals are to build neuroprosthetic devices that increase mobility, mend broken sensory connections, and enhance quality of life. Outside of lab, Noelle holds leadership positions in BME Graduate Student Council and Tau Beta Pi. (Email) (LinkedIn)


Jonel “Raven” Morris

Raven received her B.S. in Biomedical Engineering from the Indiana Institute of Technology in the Fall of 2020. Her degree was primarily focused on mechanics and the development of orthopedic implants. She will be working on the Mind In Motion project in the Human Neuromechanics Lab. She is interested in the relationship between the visual cortex and motion. Her career goal is to research for a company or lab focused on the development of visual prosthetics. (Email)




Jacob Salminen

Jacob got his B.S. degree in Chemical Engineering from the University of Florida in 2019. In his undergrad, he studied Respiratory Neurobiology and Physiology under Dr. David Fuller, in the McKnight Brain Institute (MBI). He co-authored on several papers and wrote his undergraduate thesis on histological image analysis techniques. As a post-grad, he worked under Dr. Gordon Mitchell and Dr. Yasin Seven (MBI) developing and optimizing machine learning programs for the purpose of automated quantification of neuromodulators (5HT2A/2B) in immunofluorescence images. In his PhD, he will aim to develop techniques that aid in EEG data analysis and further our understanding of brain dynamics. His research interests include biological signal processing, neurophysiology, and brain dynamics. (Email) (LinkedIn)


Nicole Stafford

Nicole received her B.S. and M.S in Mechanical Engineering from Stanford University with a focus in Biomechanics and Dynamics. During undergrad, Nicole worked as a research assistant in Scott Delp’s Human Performance Lab and as a research assistant at the Palo Alto VA and the Stanford Center for Research and Design during her master’s. Nicole is currently pursuing a PhD in Mechanical and Aerospace Engineering and her research focuses on developing a portable bionic ankle prosthesis that uses proportional myoelectric control and evaluating myoelectric control of lower limb prostheses in terms of agility. Her career goal is to work in industry related to restoring, or augmenting human movement with wearable devices. (Email) (LinkedIn)


Amanda Studnicki

Amanda graduated with a B.S. in Biomedical Engineering in 2018 from the University of Delaware. During her undergraduate studies she worked as a research assistant in the Human Robotics Lab where she studied lower limb biomechanics of normal gait to confirm or falsify common gait principles. Amanda is currently pursuing her PhD in Biomedical Engineering exploring human brain function during complex, whole-body motor tasks like table tennis. Her project uses high-density mobile electroencephalography (EEG) to reveal timing of brain activation for participants perceiving, coordinating, and interacting with objects in the real-world.
