He has experience in finance and consulting--particularly cleantech investment analysis and smart surface impact research for cities. Rob's other research includes analyzing the effectiveness of renewable energy credits, the credit rating, insurance risk, and tourism impact of city-wide implementation of climate change mitigation measures such as smart surfaces, and the increased risk coastal cities face as a result of climate change-related extreme weather events. 

 In addition to extensive research experience and analysis, he also has experience in financial modeling, operations, and marketing.

After joining Capital E in early 2018, Rob has been working to expand the scope of Capital E's recent report Delivering Urban Resilience--the first city-wide cost-benefit analysis of smart surface policies. In addition, he has been working to organize, promote, and expand the Smart Surfaces Coalition--a coalition of 40 organizations committed to the rapid, cost-effective adoption of smart surfaces to enable cities to thrive despite climate threats. 

Rob also assists in identifying and analyzing potential cleantech investment opportunities. In this capacity, he has worked on deals in renewable energy generation, green building products and materials, and energy efficiency advising.
