Update to the special plea for donations – Collins Muhadia Bisia

On behalf of Collins Muhadia Bisia, we wish to convey our deepest gratitude for those who contributed to the crowd-funding effort for the treatment of his stomach cancer this autumn. Collins impresses us weekly with his positive attitude and resilience. He receives day-long, intensive chemotherapy treatments every three weeks with some additional medication in the week following. As expected, he suffers some tough side effects, but he recovers enough between treatments to continue working on his PhD research, mainly on the data analysis from his year-long field campaign on greenhouse gas emissions from Water Pans in Kenya. Gretchen Gettel presented some of his data at the American Geophysical Union conference in Chicago this last December.
In the immediate future, Collins expects to welcome his first child – a boy – in Jan. 2023, and is excited to meet him. (He laughs because initially he was told it would be a girl – and recently found differently after buying pink clothes and toys for her.) In the meantime, he is nearing the end of the first round of chemotherapy and will likely undergo surgery in Feb. or March this year. CT scans show some progress, and he remains hopeful that the second round of chemo after the surgery will push him into remission. Collins knows that it will be a challenge going forward, and wants to thank the generosity of the ATSAF community, as this treatment would not be possible without your help.

Thank you and all the best.
