Aha Moment: A moment of sudden realization, inspiration, insight, recognition, or comprehension.
— Meriam Webster Dictionary
My goal is to experience many aha moments in life! My current research interests include:
Deep Learning approaches for upper limb prosthesis control
Classification versus RCNN Regression-based
solution for upper limb prosthesis control
Heather E. Williams, Jacqueline S. Hebert, Patrick M. Pilarski, Ahmed W. Shehata, “Evidence that a deep learning regression-based controller mitigates the limb position effect for an individual with transradial amputation,” the Myoelectric Controls Symposium (MEC24), August 12–15, 2024, Fredericton, Canada.
Demonstration of early research is below, with Classification (L) | Regression (R)

Wearable Ultrasound for Muscle Monitoring
Ultrasound provides high-resolution imaging by penetrating deep tissues, offering detailed insights into muscle function.
Currently investigating this technology in collaboration with the BEAR Lab, UC Davis, California, USA.
Quantifying Prosthesis Control Outcomes
Introduction of a Novel Suite of Metrics for Comparative Controller Research
Heather E. Williams, Ahmed W. Shehata, Kodi Y. Cheng, Jacqueline S. Hebert, Patrick M. Pilarski, “A multifaceted suite of metrics for comparative myoelectric prosthesis controller research,” PLOS One, 19(5):e0291279, May 2024.
Electromyographic (EMG) Signals, Positional (IMU) Data, along with Motion Capture and Eye Tracking technologies for the capture upper limb movement data
Gaze and Movement Assessment (GaMA):
A quantitative outcome metric for upper limb sensory-motor function
Help Shape the Future of Upper Limb Prosthesis Research
My research relies on volunteers to help me understand how people interact with physical objects and assistive technologies. To fully understand these processes, I need insights from two distinct groups of people:
Individuals with upper limb differences (including those with congenital limb differences or amputations below the elbow)
Individuals without upper limb differences (those with intact limbs)
Your unique experiences, whether you live with a limb difference or not, are vital to helping me design better prosthetic devices that offer reliable and robust motor control.

I will send you recruitment details for upcoming project(s) once approved by the University of New Brunswick Research Ethics Board.
