I'm currently a Ph.D. student at WPI studying Ubiquitous Computing and Mobile Health. A humble student of nature.



I LOVE solving problems with tools. If no tool is available, I will make one! Or, maybe, make two...



I 🏂. I 🚴. I 🏹️. I 🎣. I 🏸. I 🏓. The final frontier was, is, and always will be pushed by the CRAZIEST explorers!



Who does NOT like toys?!
