Short Bio:
Neha Panwar completed her graduation in Computer Science and post-graduation in Applied Geophysics from Kurukshetra University. She earned her Ph.D. from Department of Earth Sciences, Indian Institute of Technology Roorkee in August 2022.
Areas of Interest:
Multiphysics and multiscale characterization of rocks with scanning techniques such as, SEM, FESEM, XRD analysis, geophysical investigations using electrical and acoustic methods and high-end special tasks such as cation exchange capacity (CEC) and spectral induced polarization (SIP) measurements.
RESEARCH STATEMENT
I have experience in estimating petrophysical parameters of complex carbonate rocks using the spectral induced polarization (SIP) method, an extended version of the DC resistivity method that measures the real and imaginary parts of the conductivity. In my Ph.D., I also used complex conductivity data to estimate the pore size distribution of the carbonate rocks and validated it with mercury intrusion porosimetry. In addition, I performed bulk XRD data analysis and clay quantification of 120 volcanic powdered samples and cation exchange capacity (CEC) measurements. Moving forward, I am interested in using the SIP method for applications such as groundwater exploration, measuring hydraulic parameters like hydraulic conductivity and permeability, and performing in-situ measurements.
