I am Tianbo Chen, a rising junior at Carnegie Mellon University in Pittsburgh, Pennsylvania. I am pursuing a major in Electrical and Computer Engineering and a minor in Computer Science. My research here with Dr. Cliff Zou focuses on implementing a new type of captcha system which requires users to sort images based on abstract properties rather than having them type text. This new captcha system will help thwart automated attacks on the current text based captchas.
