We are interested in identification of novel gene/protein functions in model microbial organisms such as yeast, Saccharomyces cerevisiae and E. coli. This area of biology is often called functional genomics/proteomics and/or systems molecular biology. The two main areas that we target are translation (protein synthesis) control and DNA damage repair, both of which have implications in different human conditions such as cancer and apoptosis. We focus on pure research with some implication on the applied fields such as development of novel therapeutics. We use advanced molecular biology and molecular genetics techniques for our research.

We are also interested in chemical-genomics of various natural bioactive compounds. There are 1000s of compounds found in nature, which are capable of performing various interesting functions within a cell. However their biological implications at the molecular level have not been realized until very recently. We perform systematic approaches to investigate the target site of some of these naturally occurring compounds.

We are also vigorously involved in a number of environmental engineering projects (mostly microbiology based) and bioinformatics research and computational tool developments. For example we are the first group, which computationally investigated the global map of protein-protein interactions in any organism (S. cerevisiae).

Our research interests provide an excellent opportunity for the training of undergraduate and graduate students as well as post-doctoral fellows.
