Dr. Falguni Bhattacharya (Scientist-B)

Thrust areas of research:

• Optically Stimulated Luminescence (OSL): established Optically Stimulated Luminescence (OSL) Laboratory in Institute of Seismological Research (ISR) and have experience of OSL dating of samples from fluvial, glacial, flood-plain and inter-tidal environments. Also, working with technique part of optical dating to identify various intricacies regarding the technique.

• Planetary research: initiated planetary researches in Institute of Seismological Research (ISR), Gandhinagar and working on Mars Orbiter Mission (MOM) data to document aqueous and paraglacial features in and around equatorial region of mars.

• Tectonics and paleoseismology: determining tectonic activities and paleoseismological evidences with the help of structural and geomorphological mapping.

• Climate studies: palaeoclimatic reconstruction using the fluvial, glacial, flood-plain and inter-tidal archives.

• Aeolian studies: working on Miliolites and other aeolian deposits

• Sea-level studies: investigation of intertidal sediments and coastal dunes towards understanding the land-sea interaction

• Sedimentology: field sedimentology followed by grain-size analysis.

• Geochemistry: to understand paleoenvironment

• Morphometric analysis of drainage basin.

• Geoinformatics: GIS software applications for mapping.
