George John


George John is recognized for his active research in the field of functional molecular materials from renewable resources and their potential utility in food materials/energy technologies and materials science. After receiving his Ph.D. from NIIST-CSIR (India) in Chemistry, he held research positions in the Netherlands, Japan, and the United States before joining the City College of New York (CCNY). Currently he is a Professor of Chemistry and Biochemistry at CCNY. The research in John’s laboratory is highly interdisciplinary, and is focused on molecular design of synthetic lipids (biobased), membrane mimics, soft materials, trans fat alternatives, food materials and food chemistry, and organic materials chemistry. Current research thrusts are on (i) oleogel technology, (ii) green battery components from biomass, and the mechanistic understanding to design a future throw-away battery (iii) molecular gel based organic scintillators for cancer imaging and (iv) amphiphilic molecules, assembly and surfactants from biomass. His group has successfully developed molecular gel technologies, vegetable oil thickening agents, and trans-fat alternatives, environmentally benign antibacterial paints and oil spill recovery materials, He is a Fellow of the Royal Society of Chemistry (FRSC), a senior Fulbright Scholar, and was a recipient of the Tokyo University of Sciences (TUS) President Award, the Pfizer Visiting Professorship at (IISc) Bangalore, and the Kerala Center Award. He holds more than a dozen patents on inventions related to value-added chemicals/surfactants from renewable resources and their potential utility in food and biomaterials.

Research Interests

John’s research is rooted in the idea that innovation can be inspired by nature to develop economical and green technologies for a sustainable future. The group has harnessed crop-based precursors such as sugars, fatty acids and plant lipids to design a unique set of multifunctional soft-materials including polymers, gels and green surfactants. His group has successfully developed environmentally benign antibacterial paints, polymer-coatings, molecular gel technologies, oil spill recovery materials, battery components and oil thickening agents. As soft materials research is highly interdisciplinary and collaborative, John’s lab encourages the blending of such diverse elements including organic synthesis, green chemistry, material chemistry, interfacial phenomena, colloid science, materials and chemical engineering and biomimetics. More specifically: 

  1. Biobased Chemicals and Materials through Green Chemistry: Chemistry and Chemical Technologies in valorization of renewable organic residues as feedstocks for the production of value-added chemicals, materials and products such as green surfactants, emulsions and green cosmetics through simple organic transformations/enzyme catalysis. Multifunctional soft-materials including polymers, gels and surfactants.
  2. Design of new Oil Structuring Agents and Trans Fat Alternatives [fat mimics]: Vegetable thickening agents, trans fat free structured vegetable oil (fat) for bakery use, chocolate and cookie making. Molecular gel chemistry and technologies.
  3. Bio-derived Interfacial Chemicals in Oil Spill Mitigation Green Technologies: Phase Selective Gels. Mechanism of gel formation at the water/oil interface. Chemical Herding: Surfactant mediated oil spill mitigation chemicals and technology.    
  4. Organic Battery Components/Molecular Electrode Materials in Energy Storage Technologies: Developing non-toxic, throwaway battery components from naturally derived organic molecules (e.g. Purpurin dye, and Henna based tattoo chemical) with comparable performance to the current gold standard of Li-ion batteries.
