RESEARCH EXPERIENCE

Korea University, Seoul, South Korea

• Conducted research on paleoenvironmental reconstruction, specializing in the Ross Sea region. Employing advanced methodologies, including Beryllium isotopes, organic geochemistry, and U-Th isotopes, to analyze sediment cores. 

Indian Institute of Technology Roorkee

• Contributed to the understanding of Late Quaternary paleogeography of the Mahanadi delta, east coast of India. 

• Conducted research on the Holocene reconstruction of the Indian Summer Monsoon, employing a comprehensive multi-proxy approach to enhance our understanding of past climatic conditions. 

• Led research efforts focused on understanding climate-induced denudational changes in the Eastern Ghat region, East coast of India. Utilized sophisticated techniques such as 10Be (meteoric)/9Be, to investigate and quantify alterations in denudation in response to changes in the Indian Summer Monsoon.

EXPERTISE
