Stephen Small

Stephen J. Small is an Emeritus Professor of Biology at New York University, affiliated with the Biology Department. His research interests focus on the spatial control of gene transcription during early Drosophila development, particularly the molecular mechanisms that establish body plans in multi-cellular animals. His work explores how transcription factors and regulatory elements coordinate gene expression patterns along the anterior-posterior axis. Small's research has centered on understanding the role of gradients, such as the Bicoid gradient, in developmental patterning and how these gradients interact with repressors to position gene expression boundaries. His studies have contributed to insights into developmental mechanisms in insects and higher animals. He has been involved in teaching undergraduate and graduate courses in developmental biology and genetics at NYU.

Stephen J Small is a researcher in the Department of Biology at New York University, focusing on embryogenesis, embryo patterning, transcriptional regulation, gradients, and morphogens. His work explores how transcriptional regulation and morphogen gradients guide developmental processes in the Drosophila embryo. Key studies include the regulation of pair-rule stripes, the role of repressor gradients in segmental complexity, and the interaction between activators and repressors in stripe formation. His research also examines the molecular mechanisms underlying Bicoid-dependent patterning and the function of transcription factors like Zelda. Small's contributions highlight the interplay between transcriptional regulation and morphogen gradients in establishing spatial patterns during development.
