RESEARCH AREAS

Financial Support

We thank Council of Scientific and Industrial Research (CSIR), Department of Science and Technology (DST), Tata Chemicals, The Procter and Gamble (P&G) Company, Cincinnati , Defense Research and Development Organization (DRDO), European Union Framework Program 7 (EUFP7), startup funds from Industrial Consultancy and Sponsored Research (IC&SR), IIT-Madras and Department of Chemical Engineering, IIT-Madras for continued support.


Electrochemistry

Problems of interest include

  • Chemically modified electrodes of use in energy storage (capacitive) and generation (photo-electrochemical) under high heat and humidity conditions with support from Council of Scientific and Industrial Research (CSIR)
  • Electrochemical solutions towards water desalination using Electrogenerated Chemiluminescence (ECL) with support from Council of Scientific and Industrial Research (CSIR)
  • Designing experiments to test the Point- Defect model with support from Industrial Consultancy and Sponsored Research (IC&SR), IIT-Madras and Department of Chemical Engineering, IIT-Madras

Solid state synthesis

Problems of interest include

  • Hydrothermal synthesis of zeolites and mesoporous materials as potential catalysts
  • Conductive Magneli phases of Titanium with support from Defense Research and Development Organization (DRDO)
  • Evanescent wave chemical sensors with support from Department of Science and Technology (DST)
  • Moving cations and anions into desired locations in solids

Fuels and Ion Exchange

Problems of interest include

  • Integrated chemical and electrochemical systems for fuel generation (photochemical and photo-electrochemical) and fuel storage utilizing heat and humidity to advantage
  • Examining concepts in ion-exchange towards water desalination
  • Making Hydrogen from water with support from Tata Chemicals

Metrics for competing technologies and game theory

I look for quantifiable metrics for evaluating competing technologies. I am trying to apply game theory concepts to evaluate competition and collusion.


Scale-out

This concept will be examined based on problems and solutions in business, finance, sciences and engineering that lie outside of "economy of scale" arguments, seeking to delineate utility and economics. Problems in energy, services sector and health insurance are first attempts with the emphasis on increasing rate-of-return on investment. The broad question that I seek is a logical (maybe foolish) attempt at defining the role of finance clearly in these evaluations. Integrated chemical systems may offer one example in the sciences and engineering. The services sector offer examples in business and finance. Health insurance is another problem of interest, specifically when withdrawals (from a given insurance scheme) are more than ones paying into it; and health coverage in small businesses. I also work with students on thought experiments connecting-dots-between disciplines that may lead to new insights, through the classes I teach and the research we do.
