About Me

I'm a PhD in Ecology and Evolution and co-founder of Hacking Ecology, where I coordinate projects at the intersection of open technologies and environmental data. My academic background includes investigating climate-driven shifts in microbial diversity within aquatic ecosystems. I’ve held visiting researcher positions at the Biodiversity Research Centre of the University of British Columbia and the Centre for ICT Product Development Services and Training at the University of Zimbabwe. Currently, my work focuses on integrating experimental ecology with free/ open source technologies for environmental sensing.

What I Do

IoT and Sensor Networks

Design and deployment of environmental monitoring systems using low-power wireless networks and sustainable design principles.

Data Processing and Statistics

Development of software tools and statistical workflows to support ecological research across disciplines.

Open Hardware Development Guidance and Technical Mentorship

Supporting teams on circuit design, use cases, development strategy, and MVP optimization for open hardware projects.

Ecosystems Ecology

Research on microbial diversity, nutrient dynamics, and climate-driven changes in ecological systems.

Experimental Ecology

Field and lab experiments investigating how environmental variation influences ecological processes and patterns.
