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 interdisciplinary fields with immense potential for chemical engineers to uniquely apply their expertise as well as very rapidly growing research areas.
We analyze and engineer metabolic and gene regulatory pathways in living systems. Metabolic pathways are "traffic maps" of carbon and other elements within cells (see figure below right) and gene regulatory pathways are networks showing how this traffic is controlled by the cell. Such analysis provides insights into how metabolic bottlenecks can be relieved and how cellular performance can be boosted by engineering 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 for metabolic flux/pathway analysis and gene regulatory network deduction.
