About Me: Hi, I’m AnhPhu, and I’m a rising Junior at Harvard with a passion for engineering, science, technology, and entrepreneurship. I am special concentrating in Human Augmentation (the study of improving humans cognitively and physically), I run Harvard’s AR/VR club, where we do a lot of research and development into futuristic human computer interfaces, and am also very interested in entrepreneurship. My biggest thing before Harvard was founding/running my own phone repair store in my hometown, and now, I work for an early stage startup. I also do a lot of side projects, including building my own electric skateboards, iron man helmet, robot arms attached to your back, etc.

I can give a lot of great advice on how to get involved in tech and/or entrepreneurship at Harvard, and the resources you can access, both hardware and software!
