Research
My research is driven by my interest in in Earth’s carbon cycle. I pursue research questions of broad significance concerning the mechanistic (how?) and quantitative (how much?) influence of microorganisms, humans, and abiotic factors on the short- and long-term fate of organic carbon in aquatic sediments and Earth’s crust.
Currently, I am particularly interested in the following areas:
(a) Influence of human societies on organic carbon sequestration in and greenhouse gas emissions from aquatic sediments.
(b) Interactions between paleoenvironmental, sedimentological, geochemical and microbiological processes in controlling the long-term fate of organic carbon in marine sediments.
(c) Deciphering anaerobic microbial food webs by linking organic carbon chemical compositions to the microorganisms and biochemical processes that transform them.
(d) Role of macrobiota in driving carbon and nutrient cycling in marine and freshwater sediments.
(e) Design of sustainable strategies, including seaweed farming, to enhance the burial of atmospheric CO2 in aquatic sediments and reduce greenhouse gas emissions.
(f) Importance of tectonic processes and deep mantle-derived energy sources in sustaining subseafloor life.
All persons who are interested in interdisciplinary research on the cycling of organic carbon in sedimentary environments are welcome to contact me (mark.lever@austin.utexas.edu).
Similarly, I am always interested in supporting students with ideas of applying research in biogeochemistry and/or microbiology in areas outside the sedimentary realm, including but not limited to wastewater treatment, food and biofuel production, bioremediation, and recreational fields.
I am also a passionate hobby birder and always interested in projects that are bird-related.
