Carl graduated from the University of Illinois at Urbana-Champaign with a BS in mechanical engineering; there he had special coursework in biomechanics and MEMS manufacturing, as well as working in a research group studying self-healing composites. He was recruited by Microsoft to be a software developer and helped engineer seven releases of Windows in both the client and server SKUs, tackling tough problems in intercontinental data replication, security, and development of APIs. He then moved on to get his master’s degree from the Interactive Telecommunications Program at NYU, studying quantified self, UI and UX and systems design, molecular gastronomy, and electronics prototyping; his thesis research was a user interaction study with online dating profiles. While at Microsoft he participated in a multi-pronged weight loss program where he worked with a personal trainer, dietitian, psychotherapists, and medical doctors – this was his introduction to the world of preventative care. The program sparked a passion in quantified self to utilize data and technology to improve people's health. He enjoys cooking, mixology, gadgets, and Zumba.
