Alain Kilajian (admin team)

Senior Sustainability Specialist, IHA, London, UK

I currently act as a Senior Sustainability Specialist for the International Hydropower Association.  I mostly work on developing and implementing a suite of sustainability tools which provide guidance to the hydropower sector, as well as a means for assessing a project’s sustainability performance. I also deliver trainings and manage capacity-building projects to drive sustainable hydropower development worldwide, especially in francophone countries.

Previously, I enjoyed working as an environmental scientist on several international projects, including an iron mining project in Thailand as a Fulbright Scholar and an agricultural land-water management scheme in the Mississippi River Basin with the US Environmental Protection Agency.


I have an MPhil in Engineering for Sustainable Development from the University of Cambridge and an BA in Earth and Environmental Sciences from the University of Pennsylvania. Some of my interest including playing football (soccer), hiking up mountains, trekking through natural landscapes and backpacking through concrete jungles. I also very much love all my friends and family ;)



William van der Byl (admin team)

Analyst, Delta--ee, Cambridge, UK 

I have an undergraduate degree in Civil Engineering from the University of Cape Town. Having been introduced to the idea of sustainable development I moved to the UK to complete an MPhil in Engineering for Sustainable Development at Cambridge University.


I have stayed on in the UK and am currently an analyst working on the consultancy team at Delta Energy & Environment. My focus is low carbon heat and electric vehicles. I am passionate about contributing towards the transition to a zero-carbon future.


I dislike and suck at writing about myself but outside of work I enjoy spending time with mates, playing and watching sport, travelling when I have the opportunity and exploring the outdoors.

Marisa Lyn Henry

PhD Student, John Hopkins University, Baltimore, US 

I am currently a PhD student at Johns Hopkins University, where I will be pursing research under Dr. Paul Ferraro. My interests extend well beyond the traditionally defined environmental engineering discipline to systems design, economics, and broader social science disciplines. My focus is on using insights from behavioral sciences (particularly economics) to inform the design of more sustainable, model-based strategies for resource systems.

I am also a 2016-2017 Gates Cambridge Scholar Alumnus and graduate from Purdue University, where I earned a B.S. in environmental and ecological engineering and minor in economics.

Wenqing Liu, Tom

Senior Sustainability Consultant, GCESG, Hong Kong

I have a MSc degree in Environmental Engineering and Management from Hong Kong University of Science and Technology as well as an MPhil in Engineering for Sustainable Development from the University of Cambridge. Upon completion of my MPhil I moved back to Hong Kong to work as a consultant focusing on the research and provision of sustainability reporting for listed enterprises. This enables me to pursue my interests of the increasingly popular ESG investment in Asia and exploring the complex world of investors’ concerns in decision making from the perspective of corporate sustainability.

Dima Yankova

Ideas & Strategy, La Marina de Valencia, Spain

Shortly after completing the ESD graduate program in Cambridge, I started a 2 month internship with a Data & Analytics Consultancy in Valencia and later on I joined the Ideas & Strategy team of La Marina de Valencia, a public institution responsible for managing the old harbor of the city. Now I work on developing small-scale projects which improve the accessibility and sustainability of the public spaces in La Marina.

I hold a B.S. in Mechanical Engineering from Union College, NY and I have a combined minor in political and environmental science. My interests are constantly evolving, but for the moment I want to keep developing my amateurish website http://www.imxprs.com/free/dimz/newartwork, learn how to prepare a paella, and grow out of my 9GAG addiction.


Edward Bonner

Project Geologist, Power Exploration/ Student, Colorado

I am currently pursuing a M.S. degree in Economic Geology at Colorado School of Mines. Focusing on Cu-Mo porphyry and related deposits under the supervision of Steve Enders and Zhaoshan Chang. I received my BS in Geology from University of Vermont in 2016.


I have over two years of experience working as a project geologist in the junior exploration space, mainly for small exploration companies focused on base and precious metals. Most recently, I worked for High Power Exploration helping to generate, evaluate and plan metallic mineral exploration projects. Countries I have worked in include the US, Canada, Mexico and the Democratic Republic of Congo (DRC). My interest is in doing technical and financial evaluations of exploration projects and companies.


Prior to living in America, I grew up in Paris, France, which enabled me to work in French speaking countries like Canada and the DRC. I love traveling to exotic places, discovering new cultures and meeting people from all walks of life.

Peter Beare

Associate (Natural Climate Solutions), WBCSD, Geneva, Switzerland

I work for the World Business Council for Sustainable Development (WBCSD) on their Natural Climate Solutions project, which deals with the role of natural systems and technologies in tackling climate change. My role includes collating and presenting the private sector’s position on natural climate solutions, developing this into policy asks (to be communicated with policymakers worldwide), and coordinating the ~200 WBCSD member companies’ actions on investing in Nature. I also manage a WBCSD agricultural pilot project in central Brazil.


My specialisation is in sustainable implementation practices, the core subject of my MPhil in Engineering for Sustainable Development at the University of Cambridge (where I was a 2016/2017 Standard Bank Chairperson’s Scholar). My undergraduate degree is in Chemical Engineering, which I studied at the University of Cape Town in my home city.


When I’m not advocating for investment in Nature or interviewing development practitioners, I can usually be found dancing... Ballroom & Latin, salsa, or West Coast Swing, it only depends on what’s playing! I also love learning new languages (I’m on Italian and French at the moment...) and especially making music, usually with my barbershop quartet here in Geneva.
