The Sriram Lab's research is focused on two related areas: metabolic engineering and systems biology. Metabolic engineering is the rational modification of organisms to improve their cellular properties or performance. Systems biology is the holistic, quantitative analysis of large-scale biological datasets toward improved understanding, prediction and control of how a cell, tissue or organism behaves. Both these are very rapidly growing, interdisciplinary research areas with immense potential for chemical engineers to uniquely apply their expertise.
In particular, we analyze and engineer metabolic and gene regulatory networks in living systems. Metabolic pathways are "traffic maps" of carbon and other elements within cells. For a recent example, see this figure (SVG | caption | at publisher | article) and this figure (SVG | caption | at publisher | article). Gene regulatory networks show how protein-DNA interactions control cellular activities. For a recent example, see this figure (SVG | caption | at publisher | article). Such analyses provide several nontrivial insights, including strategies to relieve metabolic bottlenecks and boost cellular performance by manipulating select genes. Toward these objectives, we combine experimental techniques such as isotope labeling, two-dimensional (2-D) NMR, gas chromatography-mass spectrometry (GC-MS), DNA microarray analysis and quantitative RT-PCR (qPCR) with several computational techniques.
