# overview
I am an organic biogeochemist with particular interests in how organic compounds', both natural and anthropogenic, cycling affect biological and ecological processes and vice versa. These interconnected processes are important drivers for organic carbon and contaminant cycling at regional and global scales. My group uses untargeted and targeted analyses as well as data science to shed light on different aspects of organic biogeochemistry.
