Human-Oriented Robotics & Control Lab

What I Am Doing

As part of my Ph.D. program at the University of Delaware, I have the opportunity to work as a Research Assistant in the Human-Oriented Robotics and Controls Lab under Panagiotis Artemiadis. During this time, I have contributed to three main projects: human data collection on our unique treadmill (the VST), gait modeling , and the design and construction of an updated version of our treadmill. Work on these projects has consisted of both long-term independent and collaborative research. I have published the following papers with a few in review:

  • What I've Learned

    It is a privilege to work in HORC lab on projects with such potential to benefit stroke victims in the future. My time as an RA has given me a window into the world of engineering research and made me a more effective researcher. Working in the HORC lab has shown me how to read journal articles efficiently, extract important information, and synthesize that information with content from other papers. I have also been able to hone my technical writing and other technical skills such as MATLAB, python, and gait modeling. Additionally, this is the first time in my career that I am conducting long-term independent research, which has required a new level of time management and discipline. And, finally, working on more collaborative projects has helped me learn to listen well to others, and join our knowledge and ideas together to make progress toward our goals.
