My primary research lies in the intersection of computational simulation methods, machine learning models, and material science. I am deeply interested in applying the right computational methodology to discover stucture-property relationships of material system. In my PhD program, I have been mostly involved in gas-solid systems but I am open to investigate other systems as well. Some of the projects I have been involved are listed below (For publications please refer to the publication page):

Active learning for efficient navigation of multi-component gas adsorption landscapes in a MOF

  • Designed a Active learning workflow to predict gas mixture adsorption in MOFs (CO2-CH4, Xe-Kr, and H2S-CO2).
  • Developed an accuracy-based protocol as a stoppage criteria for the Active learning on gas mixture adsorption in MOFs for a pressure-mole fraction and also for pressure-mole fraction-temperature phase space (CO2-CH4, Xe-Kr, and H2S-CO2). For more details, visit the github page of the project. [Github] [Publication]
Active learning workflow for modeling gas mixtures adsorption in a MOF

Sequential design of Pure component adsorption simulation in MOFs

  • Implemented an Active learning protocol (using Gaussian Process regressions) to predict CH4 and CO2 adsorption in a Cu-BTC metal-organic framework (MOF) for a temperature-pressure phase space, and demonstrated a reduction of 97-98% of the total data requirement with comparable accuracy to high-fidelity monte carlo simulations.

Active learning workflow for modeling single component gas adsorption in a MOF

Discovery of nanoporous materials for a multi-purpose gas sensor from the CoRE MOF database (collaborated with Jack Gonzalez)

  • Led and assisted an undergraduate student, Jack Gonzalez, to calculate selectivity of 30 gas mixtures (all combinations of CO2, N2, N2O, O2, CH4, and H2O) on the CoRE-MOF database (> 9000 structures), performed the structure-property analysis, and recommended MOF candidates for gas sensing.

Computational workflow for discovery of sensor candidate materials from the CoRE database

Machine learning and descriptor selection for the computational discovery of metal-organic frameworks (Review Project)

  • Through my literature review work, a paper was published which highlighted how machine learning and specific descriptors (chemical or physical features fed to a machine learning model) were used to design and discover new MOFs. The papers also includes many pedagogical introduction to the field of MOFs, Machine learning, feature selection, as well commentary on the future of the domain. [Publication]
