I graduated from the University of Pittsburgh with a MS degree in bioengineering. I also received my bachelor's degree in engineering science here at Pitt. Through my education, I developed a solid background in mathematics and physics. I am a fast learner and enthusiastic about learning new knowledge and facing challenges. Such characteristics made me a highly interdisciplinary person. My current work is mostly related to image processing and image registration but includes providing programming solutions to the analysis of all kinds of other data as well. I also involved in projects related to finite element modeling as well as inverse modeling with virtual fields method. - GitHub: https://github.com/Ziyi-OBM - Programming and software skills: MATLAB, Python, C++, ImageJ, Linux, Git, Microsoft office.
