our founder

Ellipsis Earth was founded by research scientist, environmentalist and award-winning science communicator Ellie Mackay.

Mackay studied at Cambridge University and Imperial College London to gain BSc and MSc degrees in natural sciences and science communication. She has over a decade of experience as an educator, having worked as a secondary science teacher and Head of Biology, Oxbridge and G&T leadership manager, and Deputy Dean of Higher Education in international schools. Her years of hands-on experience in the classroom means she understands how to encourage the very best from her students, employing a wide range of novel educational methods to challenge, inspire and engage students at every academic level.  As an award-winning educator she was instrumental in her schools' curriculum development, before taking on leadership and consultancy roles in Science and STEM education across SE Asia. 

She is also an extreme environment drone pilot, podcast host and film director, telling the stories that matter most from around the world.

Mackay's vision for Ellipsis Earth is to create a complete ecosystem for

positive environmental change, through scientific research, education and

creative communication, all underpinned by Ellipsis’ expert use of technology.

She is a proud global ambassador for WomenTech, an Airwards #dronesforgood judge,

and a keen advocate of inclusivity and equality in STEM and Tech. 

Mackay is supported by an experienced and dedicated team of specialists, all of whom share her desire to harness real-world data and drive lasting impact, and passion to connect the next generation to key scientific issues.

"I have seen first-hand the power of understanding, storytelling and solutions-focused empathy to create global citizens and
real-world impact" 

Ellie Mackay, Founder & CEO of Ellipsis Earth

"Every school should have a Miss Mackay"

our mission

The goal of Ellipsis Earth is to power informed decision-making by providing robust and comparable data on environmental pollution around the world. 


Without reliable data, our best efforts are being wasted - solutions are wrongly applied, poorly targeted, inefficient and ineffective. 


By using our platform, we can identify trends and measure impact, celebrate big wins and target critical hotspots.


Ellipsis Earth also champions effective science communication, to tell the right stories to the right audiences and create the most lasting impact.


Data tells a story. Stories drive change. Changemakers make the world a better place.
