William C. Nierman mainly focuses on Genome, Genetics, Gene, Fungal genetics and Whole genome sequencing. His Genome research focuses on Aspergillus nidulans and how it relates to Metabolic engineering, Penicillin and Penicillium chrysogenum. Genetics and Insertion sequence are two areas of study in which he engages in interdisciplinary work.
His Gene study frequently links to related topics such as Microbiology. Within one scientific family, William C. Nierman focuses on topics pertaining to Aspergillus fumigatus under Fungal genetics, and may sometimes address concerns connected to Aspergillus and Regulation of gene expression. His Sequence analysis study combines topics from a wide range of disciplines, such as Phenotype, Fungus and Genomic organization.
