Current Students

Marjorie Carlson

Marjorie Carlson is a Master's in Computer Science student at Carnegie Mellon University; she also holds a degree in International Relations and has lived and worked in three countries, including spending six years in Qatar. During Summer 2015, Marjorie is developing firmware and software for the Stand-Alone Braille Tutors. She is excited that TechBridgeWorld offers her the opportunity to bring together her interest in international development issues and her skills in systems programming.

Kangwei Chen Kangwei Chen is a visiting research intern at Carnegie Mellon University. He recently received a bachelor's degree from Cornell College in Computer Science. Kangwei is a part of the Assistive Robots for Blind Travelers project and is focusing on the Baxter Research Robot. His current research interests include assistive technology, humancomputer interaction, agent-based modeling, and system design. In his free time, he enjoys blog reading, swimming, and traveling.
Eric Hochendoner

Eric Hochendoner is an Electrical and Computer Engineering student at Carnegie Mellon University.  He is responsible for Android development for the NavPal and Assistive Robots for Blind Travelers projects.  He is excited to be able to use technology to help blind and others with disabilities.  In the past, he helped develop an Android powered robot designed to study the effects of robot presence on human behaviour.  In addition to his research, he has shared his passion for computer science as a Teaching Assistant with CMU's Andrew's Leap summer program for high school students.  More recently, he has served by helping to teach the Electronics and Electricity Boy Scout merit badges at Alpha Phi Omega's Merit Badge University.  Eric also enjoys reading science fiction and fantasy, video games and exploring the natural world.

Allan Wang Allan Wang is a junior Mechanical Engineering major at Carnegie Mellon University. He came to CMU knowing nothing about robotics. However, guided by his passion to realize cheap, long-term care for the people in need through technology, Allan worked hard to gain experience in robotics. He's been an active member and a tutor in the Robotics Club’s RobOrchestra project. And he became a skillful programmer after a series of harsh computer science classes. During Summer 2015, Allan is working on the mechanical design of a harness system for TechBridgeWorld's Assistive Robots for Blind Travelers project. He is very excited about working with the team members involved with the project to help develop a solution to that could benefit blind and visually impaired travelers.
Zhi Tan

Xiang Zhi Tan is a PhD student in Robotics at Carnegie Mellon University's Robotics Institute. He received his B.S. in Computer Science from University of Wisconsin-Madison with research experience in the field of Human-Computer Interaction and Human-Robot Interaction. His research lies in designing and creating helpful robots that would assist people in real life situations. He is part of the Assistive Robots for Blind Travelers working on Rathu Baxter. He spends his free time watching movies, traveling, running and making weird inventions that never see the light of day.

Susan Zuo

Susan Zuo is a junior Electrical and Computer Engineering student at Carnegie Mellon University. In the past, she worked on an independent study to design and implement a game for TechCaFE that is accessible to blind learners but also engaging for sighted learners. In addition to her independent study, she also works on the Braille Tutor project with TechBridgeWorld, where she conducts a series of tests to enhance the user experience. She is also involved as an active member in organizations and clubs like Engineer Without Borders, Robotic Club and Society of Women Engineers. She enjoys painting, running, reading and cooking in her spare time as well.


We acknowledge the Spring '13 15-237 Cross-Platform Mobile Web Apps course students for their contributions to TechBridgeWorld. Through their coursework, they developed a donor tracking tool.
