Dwain Rogers My own career began as an attorney in the 1990s, primarily working in the areas of intellectual property and early stage tech finance.  I moved into the Government sector in 2003, working at the Texas General Land Office for eleven years as an attorney, as Special Counsel to the Land Commissioner and finally as Deputy Commissioner for Renewable Energy.  In that post, I was tasked with leasing state owned lands for utility scale renewable energy projects and the work sparked a fascination with renewables, clean tech and energy markets that has become my passion.  After the Land Office, in 2012 I accepted a position as Research Director at the Texas Sustainable Energy Research Institute at the University of Texas at San Antonio.  There I focused on cutting edge research involving distributed energy technologies, energy storage, smart grid and internet of things initiatives, and renewable energy.  My role at UTSA was often to look at projects from a holistic perspective that included engineering, economic and policy considerations, all of which are in my opinion critical to the successful adoption of new energy technologies.  I love to look at big problems from a systems perspective, and I hope to bring this sort of thinking to my new role at CleanTX.
