research approach
My research investigates geochemical processes occurring in planetary aqueous systems in (partially) closed, interior liquid water under the icy crust of ocean worlds and on (sub)surface water bodies on relict water worlds by employing a combination of laboratory experimentation, geochemical modeling, and field investigations. .
EXPERIMENTAL AQUEOUS GEOCHEMISTRY
Why Experiments?
While much of planetary science is done by observation and modeling, quantification of geochemical constants and verification of theoretical hypotheses require experimentation.
Experimental Conditions
I conduct experiments at low-temperatures (< 500 K) conditions in aqueous systems similar to Water Worlds, Mars, Europa, Enceladus… Future experiments also include Venus-like surface conditions
ANALOG FIELD INVESTIGATIONS
Why go to the field?
We have very limited information and access to planetary materials… so we find out places on Earth that are similar and investigate them instead
My field Locations
I conducted field studies in the Deccan traps region in India. The basalts are heavily weathered and are excellent Mars analog sites
GEOCHEMICAL MODELING
Why do geochemical modeling?
Conducting experiments at some geochemical conditions is not possible. We use thermodynamic and kinetic data to extrapolate our understanding at extreme temperature & pressure conditions and planet-specific aqueous systems
Geochemical Modeling Aids
I primarily use The Geochemists’ Workbench Software to conduct geochemical simulations. I am also learning other specialized software like FREZCHEM and CrunchFlow
