Research Interests

Dr. Erramilli’s research interests include: Development of Infrared and Raman microscopy for imaging biological samples, using intrinsic contract mechanisms; Applications of Scanning Near-field Infrared Microscopy for imaging single living cells, with a view to understanding the contribution of membrane lipids to the physics of cell motion; Application of high resolution vibrational microscopy for screening pathological tissue; Specifically seeking to correlate vibrational microscopy data with synchrotron x-ray scattering data; Development of vibrational infrared pump-probe 2-D spectroscopy for the study of biomolecules; Development of novel infrared fibers (silver halide) and Quantum Cascade Laser sources for biomedical applications. [Collaboration with Prof Irving Bigio]; Development of Quantum Raman Microscopy using entangles photons.

Current Research

Dr. Erramilli’s group is working on high-resolution infrared microscopy for studying biological systems. Images are obtained by using a Scanning Near-field Infrared Microscope, based on a tunable infrared laser. The pulse width of the laser is about 100 femtoseconds, which is useful for studying ultrafast dynamics in biomolecular systems.
