Consultancy

I am available for consultancy work related to mapping forests and trees through my company forestmap.ai. I apply advanced AI and computer vision techniques to remote sensing data for tropical forest tree detection and monitoring. My services can be beneficial for environmental consulting firms, governmental and non-governmental organizations, and businesses in sectors such as sustainable forestry, conservation, climate change mitigation, and ecological research. With an established track record in the application of cutting-edge technologies, I offer consultancy in project design, data analysis and interpretation, as well as the development and implementation of AI-based solutions tailored to your needs. If your organization requires support in these areas or has specific project needs, please feel free to contact me.

2019, NERC PhD studentship

2017, AECOM Prize for outstanding overall academic performance (Imperial College London)

Supervision

Teaching

Undergraduate supervision: Responses to Global Change, Natural Sciences Tripos, Part II, University of Cambridge.

2023, Janet Moore Prize - nomination:

James has given clear and helpful supervisions and essay feedback. He’s instilled a confidence in my essay writing I have never had and I can’t stress how much that has affected my confidence going into my final exams. I feel that I am as well prepared as I could be for not just PL2 but other essay modules as well (e.g. ZM2 conservation science). His feedback focuses not just on the particular essay question but on essay writing technique for the module in general which has allowed me to improve in my essay writing each week despite changing between lecture series. With James’ supervision I have found myself enjoying writing essays each week! And the James’ supos always inspire conversations over new links within and between lecture series ideas.
