Area of Interest:

  • Metabolic engineering for redesign of hosts as an ideal platform for recombinant protein expression
  • Bioprocess monitoring and modeling of recombinant cultures
  • Scale-up of recombinant protein production

Summary of Research:

Our work is at the interface of molecular biology and biochemical engineering, where genetic engineering tools are used to construct a range of host-vector combinations required to over-express recombinant proteins and these are then tested and optimized in a bioreactor. We have also initiated work in metabolic engineering where the host for expression is redesigned so as to divert the metabolic fluxes towards recombinant protein synthesis. We also do online process monitoring utilizing biophysical tools like fluorescence, capacitance, NIR, etc. to study and model the metabolic state of the cell. Since we work with therapeutically important recombinant proteins these find natural use in pharmaceutical industry. We have initiated many University-Industry collaborations where long-term projects have been set up leading to technology transfer
