Mark Buchheim's primary research interests are focused on the phylogenetic reconstruction and molecular evolution of the green algae with particular emphasis on the genus Chlamydomonas and its allies (including Carteria, Chloromonas, and Chlorococcum). In addition, he remains interested in the enigmatic group of green algae known as the Sphaeropleaceae. His lab has been a leader in the use of ribosomal (18S, 28S and ITS) and chloroplast-encoded rbcL and atpB genes to infer phylogenetic relationships in the green algae. Buchheim served as PI and member of the Executive Committee of Deep Green, a USDA/NSF/DOE-funded project involving the coordination of research effort in green plant phylogeny (i.e., the study of phylogenetic relationships among the major green algal and embryophyte lineages). He also collaborated on a multi-investigator project to study microbial diversity at the Great Salt Plains of Oklahoma. Current research interests include diversity of the blood alga (Haematococcus) rRNA secondary structure analysis, sequence-structure data in phylogenetic reconstruction, rRNA intragenomic variation and the relationship between concerted evolution and sexual reproduction in green algae. In addition, graduate research in the lab has focused on Aspergillus diversity, molecular characterization of Juniperus pollen and the design of microbial consortia for wastewater remediation.
