At NREL Since: 
2008

Dr. Venkat Subramanian received his Ph.D. from the University of Cincinnati in the year 2008. His research at NREL has focused on understanding the metabolic pathways leading to H2 production in the green alga, Chlamydomonas reinhardtii, using proteomic and metabolomic approaches. He has also been involved in characterizing mutant algal strains that are deficient in fermentative pathways in this organism using omics techniques. His current research focuses on genetically improving the harvesting properties of algae for commercial-scale biofuel production.

Dr. Subramanian’s Ph.D. thesis involved characterization of cytochrome P450 monooxygenases in the white rot fungus Phanerochaete chrysosporium, their heterologous expression and purification, and understanding their global transcriptional regulatory patterns under varying environmental conditions. His master’s thesis involved molecular analysis of transcriptional activators in the yeast Saccharomyces cerevisiae. His other research interests include annotating cytochrome P450 genes in fungal genomes, and identifying and developing strategies for improving the production of alternate renewable biofuels from algae.
