Braden is a software developer and technology enthusiast. He is the co-founder and CEO of TechNotes and the CTO of OpenCraft. Prior to TechNotes, Braden’s most recent major project was LabXchange, an online platform from Harvard University which provides world-class life sciences education materials to the world on-demand and for free. Braden led the software development for the project, which went on to have over two million users in its first year and won the 2020 Open edX Prize for creating the most impactful technical project built with Open edX.

An avid programmer since childhood, Braden has worked with a wide variety of projects, platforms, and programming languages over the years. Braden is known for his deep technical knowledge, his wide-ranging experience, his approach to understanding problems from many perspectives, his ability to communicate clearly, and his relentless optimism.

Outside of work, Braden has enjoyed serving on several non-profit boards, notably the OGO Car Share Co-op which brought car sharing to BC’s Okanagan Valley and was acquired by Modo. Braden holds an Honours B.Sc. in Physics from the University of British Columbia, where his studies included classical and modern physics, mathematics, computer science, cryptography, and philosophy.

Joel is a co-founder of TechNotes, a Postdoctoral Fellow in The Keith Group at the Harvard John A. Paulson School of Engineering and Applied Sciences, and the Chief Administrative Officer at the education technology company Agents of Discovery.

He started his career as an intern in the office of former California Governor Arnold Schwarzenegger, and went on to hold Senior Analyst roles at Pic River Energy (a wholly indigenous-owned clean energy infrastructure developer) and the Ontario Power Authority (the creator of major electricity procurement programs). Alongside this private sector work, he earned a B.A. at the University of British Columbia, an M.Sc. at the University of Oxford, and a B.Sc. at the London School of Economics, then completed a Ph.D. under climate scientist Danny Harvey at the University of Toronto in 2019.

Joel has taught several undergraduate classes, published numerous academic articles relating to energy and the environment, written over 50 book reviews on a range of technical and popular topics, and undertaken visiting research appointments at research centres affiliated with Imperial College London and the University of Oxford. His current research assesses the challenges and opportunities facing environmental NGOs in solar geoengineering governance, while his private sector work outside of TechNotes focuses on using augmented reality, geolocation, and other tools to make science and culture education more engaging.
