Regular biography
Alan D. Grossman is a Fellow in the Department of Biology at the Massachusetts Institute of Technology. His research focuses on mechanisms and regulation of DNA replication, gene expression, and horizontal gene transfer in bacteria, with a particular emphasis on the Gram positive bacterium Bacillus subtilis. His work explores the control of horizontal gene transfer, especially integrative and conjugative elements (ICEs), and the regulation of DNA replication initiation through the DnaA protein. Grossman's research addresses fundamental processes in bacterial propagation, adaptation, and stress responses.
Scholar-generated biography
Alan D Grossman is a researcher at the Massachusetts Institute of Technology, focusing on molecular genetics and microbiology. His work explores the regulation of gene expression, bacterial DNA replication, and the mechanisms of genetic competence and sporulation in Bacillus subtilis. He investigates the role of sigma factors, such as sigma 32 and sigma H, in stress responses and developmental pathways. Grossman also examines integrative and conjugative elements (ICEs), chromosome partitioning, and the impact of (p)ppGpp on DNA replication. His research integrates genetic, biochemical, and molecular approaches to understand bacterial physiology and gene regulation.
