Optical fiber lasers are very attractive because of their compact size, simple design and high efficiency. They have applications in wavelength division mutiplexing systems for long distance transmission, spectroscopy, sensors and instrumentation. Dr. Das's research concentrates on the development of high power fibre lasers in the visible and in the infrared regions of the electromagnetic spectrum. The work will also develop a highly sensitive sensor for measuring temperatures and pressure in harsh environments using the fiber lasers. A high power multi-wavelength fiber laser in the infrared region will find application in industry, environmental monitoring and biomedical research. This laser emits a number of lasing lines simultaneously with high power. It is possible to select a particular lasing line or a group of lasing lines depending on the requirements of the application. For differential absorption measurements one can use two laser lines with high power which may be tuned over a wide spectral range: one as a reference and the other to detect a different gas signal. A laser emitting a number of lasing lines with high power in the visible region of the electromagnetic spectrum is also attractive. This laser will be applicable for displays, printing technology, medical diagnosis, treatment (e.g. photodynamic therapy for cancer) and development of a new system for biomedical research.

The major project in my group is the study of molecular mechanisms of interactions between pathogenic bacteria and lung epithelial cells, with an emphasis on the role of innate immune receptors. We try to dissect specific pathways, which help pathogenic bacteria to escape host innate immune defences and establish an infectious process. Our ultimate goal is to identify new molecular targets for therapy of pulmonary disease caused by the opportunistic pathogen Pseudomonas aeruginosa.
Our research is focused on the metabolic and community ecology of altered environments. Human activities often create change in the form of multiple stressors, altering the community composition of aquatic ecosystems. Accurately measuring those changes is a critical first step to understanding ecosystem responses to stress. Our research group focuses on understanding how those community changes alter ecosystem energetics and function. Two broad research themes are: 1) understanding the role of multiple stressors (e.g., climate change, commercial and recreational fishing, species invasions) on the community structure and energetics of aquatic ecosystems and 2) understanding ways in which the behaviour and life histories of aquatic organisms can influence population size and ecosystem structure.
