Lab Personnel
Post Doctoral Researchers
Graduate Students
PhD Candidate, Dept. of Biomedical Engineering
Preethisiri Bhat
2020 BS Bioengineering, University of California, Berkeley
​
Preethi is interested in uncovering how somatosensory information is encoded in the cortex, and how this understanding can be used to develop peripheral nerve stimulation patterns that evoke naturalistic cortical activity.
PhD Candidate, Dept. of Biomedical Engineering
Jonah Mudge
2021 BS Biomedical Engineering, Minor in Computer Science, University of Wisconsin-Madison
​
Jonah's research focuses on characterizing proprioceptive percepts in upper-limb amputees and aims to benefit amputees by improving proprioceptive feedback in neuroprostheses.
PhD Candidate, Francis Payne Bolton School of Nursing
Clinical Research Nurse Coordinator, Louis Stokes Cleveland VA Medical Center
Meilissa Schmitt
2005 BS Nursing, Kent State University
Melissa currently works with a multi-disciplinary team that applies electrical stimulation to the residual nerves in amputees to provide sensation from prosthetic hands or feet. Her research interest includes seeking to understand the psychosocial experiences of upper limb amputees.
PhD Candidate, Dept. of Biomedical Engineering
Bronwyn Spilker
2022 BSE Biomedical Engineering and Psychology, Minor in Electrical Engineering, Case Western Reserve University
​
Bronwyn studies how learning strategies can be utilized to supplement a biomimicry approach to sensory reeducation to allow participants to more naturally embrace and use ICMS or PNS stimulation in place of lost sensation.
PhD Candidate, Dept. of Biomedical Engineering
Roberto Peralta
2022 BS Mechanical Engineering, Minors in Mathematics and French, University of Arizona
​
Roberto is interested in developing biomimetic peripheral nerve stimulation paradigms to improve quality and replicate texture sensations. Roberto uses in-silico models to inform and iterate on these paradigms.
PhD Candidate, Dept. of Biomedical Engineering
Brianna Hutchison
2019 BS Electrical Engineering, University of Michigan
​
Brianna is a BME PhD student at Case Western University co-mentored by Dr. Graczyk and Dr. Ajiboye. She is exploring the neural representation of tactile sensation. She is helping the ReHAB team restore upper limb functionality to people with spinal cord injuries, focusing on providing tactile feedback to improve grasp dexterity.
Staff
Study Coordinator
Jessica Jarvela (née Walrath
MS Pathology, Case Western Reserve University
BS Biology, University of Dayton
​
Jessica's primary focus is providing administrative support to both the clinical and technical project teams for the laboratory's multiple projects. This includes coordinating test subject scheduling, documentation and maintenance of research data, support completion of regulatory documents for the FDA, IRP, and/or project sponsor as required, as well as assist the quality systems engineer and systems engineer in generation of all quality system documentation.
Research Occupational Therapist, Louis Stokes VA
Chris Cowen
1995 BS Occupational Therapy, Cleveland State University
​
Chris works with our research participants to train them in the use of state of the art, high DoF prostheses. She aids in subject recruitment - speaking with potential subjects, answering questions about studies and conducting functional measures during initial screenings - and is the point of contact for all upper extremity amputee participants serving as a patient advocate.
