Sanitation Industry Specialist - Emerging Markets
Tate Rogers is the founder and an Environmental Consultant at Triangle Environmental. He completed his M.S. and B.S. degrees from North Carolina State University where he first developed an interest in sanitation. Tate has supported the design, construction, lab and field testing of novel systems spanning the sanitation value chain since 2011. Tate has field tested over a dozen prototypes in countries including South Africa, Malawi, Zambia, Rwanda, Madagascar and India. Tate has worked with several lead teams in the sanitation technology space including NC State University, RTI International, Duke University, NASA, Biomass Controls and Crane Engineering.
In his free time, Tate enjoys music and going to concerts, traveling, and hosting the weekly Toilet Tuesday in Durham, NC.
Dr. Nicola Greene has been based in East and Southern Africa since 2014 with a specific focus on improved fecal sludge management. Nicola is an engineer by training and holds a PhD in Civil Engineering from the Water Engineering and Development Centre (WEDC), Loughborough University. Nicola is focused on the practical aspects of the on-site sanitation market and the industries within it; assessing the needs of the key players and matching these with emerging technology and service design.
She brings a broad perspective having worked in Rwanda, Kenya, Zambia, Uganda, Ethiopia, Sierra Leone, Malawi and Nepal; across a range of stakeholders including NGOs, Social Enterprises, Private Sector, Utilities and Local Government.
When not focused on fecal sludge, Nicola enjoys mentoring small businesses, making things, and spends most weekends on a mountain bike.
Research and Development Manager
Implementation and Servicing Manager
Dr. Aaron Forbis-Stokes is a Sanitation Technology Consultant at Triangle Environmental. He received his Ph.D. at Duke University in Civil and Environmental Engineering in 2017. His doctoral work focused on the "Anaerobic Digestion Pasteurization Latrine (ADPL)," a self-sustainable, off-grid fecal sludge treatment system. His leading efforts with the ADPL progressed the innovation from a lab-scale experiment to 6 full-scale prototypes operating across 3 countries, some of which have operated for over 5 years. Technical fields of work included digester design optimization, biological nutrient removal, and microcontrols for system operation and remote data acquisition.
As a member of Triangle Environmental, Aaron has continued collaboration with ongoing research at Duke University as well as branched out to working with other teams, like Crane Engineering. Aaron’s combined experience in multi-disciplinary research and development, international implementation and operation with multiple partners, and technical communication make him an effective collaborator in multiple stages in the development and market application of sanitation technologies.
Outside of work and being a regular attendee of the Durham Chapter of Toilet Tuesday, Aaron loves spending time in the great outdoors, exploring new territory, and being on a bicycle.
Sarah Hennessy supported the installation and commissioning of Duke University Center for WASH-AID's toilet prototype, with RTI International in India, and with Triangle Environmental in South Africa. Sarah is currently stationed in Kenya, providing technical engineering support to Sanivation and exploring viable commercialization routes to bring innovative technology to market. Sarah is experienced working on collaborative, multi-disciplinary projects with professionals from academia, industry, government, and non-governmental agencies. Sarah’s work with diverse teams has provided her a widespread network of experts, helping her holistically field test technology prototypes. This integrated approach will aid in the transition from field testing to successful commercial implementation.
Sarah holds a B.S. in Chemistry from Furman University and a M.S. in Environmental Engineering from Clemson University. When not at work, Sarah loves exploring the great outdoors by foot or bike with her husband Jeff, her hammock, and a good book.

Dr. Caroline Saul recently relocated back to North Carolina after spending five years working in the Business Innovation Group at Eawag in Switzerland. At Triangle Environmental, she heads up new business development and service design to complement our technical research.
Caroline’s background in Environmental and Energy Engineering and Economics has motivated her to work towards developing systems for extending basic services to all. She has worked in Indonesia, Uganda, Burkina Faso, Haiti, and Kenya. At Eawag, her research consisted of longitudinal case studies of water and sanitation service providers in low-income countries. The primary focus of her research has been business model innovation in container based sanitation service providers and water kiosk operators, particularly the roles of digital technologies in operational models.
Outside of the office, Caroline can be found on an Ultimate (frisbee) field, fly fishing, or scuba diving.
