Dr. Freeborn is an associate professor in the electrical and computer engineering department at The University of Alabama (UA) in Tuscaloosa. His research interests span sensors to measure biological tissues, biomedical signal processing for health applications, and fractional-order circuits and systems. Research in his laboratory has developed wearable sensors for characterizing knee joints and tissues (focused on knee osteoarthritis), characterized alterations in tissues resulting from exercise-induced fatigue, developed systems to track segmental fluid shifts in the body, and evaluated non-invasive methods to characterize laryngeal tissues.
Dr. Freeborn is also actively engaged in promoting undergraduate research experiences for students. Through these efforts he has coordinated sites at the University of Alabama to engage students in innovative engineering using renewable resources, provided opportunities to design circuits and signal processing methods to support speech pathology applications, and explore fractional-order circuits and systems as part of an international collaboration with the Brno University of Technology in the Czech Republic.
His research has been supported by the National Science Foundation, the National Institutes of Health, state agencies and private industry.
