Where to get help
If you need help editing or submitting your draft, please ask us a question at the AfC Help Desk or get live help from experienced editors. These venues are only for help with editing and the submission process, not to get reviews.
If you need feedback on your draft, or if the review is taking a lot of time, you can try asking for help on the talk page of a relevant WikiProject. Some WikiProjects are more active than others so a speedy reply is not guaranteed.
To improve your odds of a faster review, tag your draft with relevant WikiProject tags using the button below. This will let reviewers know a new draft has been submitted in their area of interest. For instance, if you wrote about a female astronomer, you would want to add the Biography, Astronomy, and Women scientists tags.

Swedish professor
Henrik Drake
Born
Sweden
Known for
Deep biosphere research, microbial methane cycling, isotope geochemistry
Henrik Drake is a Swedish geochemist and geobiologist, currently serving as a Professor at Linnaeus University, Department of Biology and Environmental Science. His research focuses on the deep biosphere, ancient microbial life, and microbe–mineral interactions in fractured crystalline bedrock and impact craters.
Academic background and career
Henrik Drake earned his PhD in geology at University of Gothenburg and applies a multidisciplinary research profile combining geochemistry, microbiology, and isotope geoscience.
Research focus
Drake's research centers on:
Microbial methanogenesis and sulfate reduction in deep fractured bedrock
Isotopic biosignatures (δ¹³C, δ³⁴S, clumped isotopes) of ancient microbial activity
Impact structures (e.g., Siljan crater) as analogues for astrobiological environments
Microbial interactions with minerals, including uranium and arsenic immobilization
Thermochronology of Precambrian cratons to assess long-term habitability
