Xin ‘Sally’ Zheng

Sally is a PhD student at the NTE lab. She received her B.S. degree in Biomedical engineering from the Illinois Institute of Technology where she worked with Dr. Philip Troyk developing a highly sensitive fingertip force sensor for limb prosthesis. She received MSE degree in Biomedical Engineering from the University of Michigan at Ann Arbor. During her time at Michigan, she worked at the Neuromuscular Laboratory lead by Dr. Paul Cederna where she developed a computational model predicting the effect of electrical stimulation for sensory axonal activation within a regenerative peripheral nerve interface for sensory feedback in limb prostheses. Her long term research goal is to employ a multimodal approach to improve the chronic performance of neural electrodes for neural modulation.

Current Projects:

• Soft elastomeric electrode for intramuscular stimulation and drug release
• Chronic performance of iSODm coated neural probes
• Using imaging techniques to characterize chronic microstimulation stability and to compare state-of-the-art electrode materials for intracortical electrical stimulation

Hobbies:

Knitting, long distance running, cooking, painting, accordion
