Jinann Abudagga is a high school senior at West High in Iowa City, where she is a member of both the swim and robotics teams. She also serves on the Student Leadership Board of Iowa FIRST Robotics, where she represented the FIRST Tech Challenge Iowa at the World Robotics Competition in 2024. Jinann spent time developing Dance Robots with Dr. Totah and the Robotics & Assistive Devices Lab this summer, which will be displayed on stage. She is currently applying to colleges to pursue an engineering degree.

Dr. Deema Totah is an assistant professor in the Department of Mechanical Engineering at the University of Iowa, and director of the Robotics and Assistive Devices Laboratory (RAD Lab). Dr. Totah’s research interests lie in improving the efficacy of assistive devices for customized patient care through experimental, musculoskeletal biomechanics research. She is passionate about building robotic and mechatronic systems with integrated wearable sensing to test assistive device properties, study human movement and behavior, and understand how humans and devices interact with each other.  Prior to joining UI in 2021, Dr. Totah completed a postdoctoral fellowship at the University of Michigan’s School of Kinesiology. Dr. Totah received her Ph.D. in 2020 and M.S.E. in 2014, both in Mechanical Engineering from The University of Michigan. She received a B.S. from the Mechanical Engineering Department at MIT in 2012.

Zachary Williston is a graduate student studying Mechanical Engineering with a focus in kinematics and dynamics. From a mechanical design standpoint, he is interested in anything with at least two wheels, with plans to pursue a career in research and development. His work in the RAD lab focuses on a multi-planar AFO Testing device. Additionally, he is involved in sports clubs, including the Triathlon and Cycling.

Xandra Abel is an undergraduate student studying mechanical engineering. She was awarded a kickstart grant from the engineering library for her work in the RAD Lab, where she is designing and building a table for individuals in wheelchairs. These individuals often struggle to sit comfortably at low tables at home or in restaurants, so her design would allow them to sit at the table while being close and comfortable. ​

Wilensky Coleau is an undergraduate student studying Electrical Engineering at Stony Brook University (SBU) , NY. He was part of the Research Experience for Undergraduates (REU) program at the University of Iowa where he worked on creating the first-generation prototype of the wrist-hand exoskeleton at the RAD lab. Additionally, he is part of the E-board of National Society of Black Engineers (NSBE) at SBU and is interested in weightlifting and volleyball. Being part of the REU program has influenced him to potentially pursue a Ph. D. in the future after graduation. 

Ian will complete a duel B.S. degree in mechanical and electrical engineering in the Fall of 2023. At the RAD Lab, he worked on revamping and designing a new clamping mechanism for an AFO stiffness measurement apparatus. After graduation, he would like to pursue a career as a design engineer in the medical or aerospace field. Outside of school, he enjoy playing tennis and building rockets.
