Most Significant Contributions
1	Air Pollution Control : ¨Urban Photochemical smog formation potential was predicted for New Delhi, during the winter months of 1996 with an ambient air quality monitoring of surface O3, NOx, PAN, TSPM, Respirable suspended particulate matter (RSPM), PM10, PM100, vehicular source (strength) emission monitoring together with micro- meteorological parameters, surface ozone, NOx , PAN, solar flux and solar day data. Published in the Elsevier journal of “Atmospheric Environment” Part B Urban Atmosphere.
2	Solid waste management : BMP in to SMP: An alternative method of Stoichiometric methane potential (SMP) based on empirical formulae of different solid wastes developed in this work replaced the traditional time consuming BMP method of solid waste. This was standardized, calibrated and confirmed with experimental evidence and made as a simple protocol for assessing the methane potential of solid wastes for AD.
3	Industrial Effluent treatment : CSTR into CSTD: Adenosine Triphosphate (ATP) based bio kinetic design constant was developed for anaerobic digestion of solid wastes. (Published paper enclosed). This has replaced the traditional VSS based assessment of biomass inside the anaerobic digester and paved a path to rename the liquid waste anaerobic system as “anaerobic CSTR and solid waste anaerobic system as “anaerobic CSTD”.
4	Bioenergy : SLAMBI Anaerobic digester gas mixing was developed and patented as an efficient biogas mixing technology for Gas Liquid and solid separation inside the digester as a replacement for expensive impeller based sensing potential.
5	Rheology and Computational Fluid Dynamics of Anaerobic digesters : The residence time distribution analysis at various rheology, OLR, HRT and biokinetics have been experimented and Masters Degree thesis was supervised on “ Multiphase flow gas mixing modeling of anaerobic digesters” work carried out by Mrs Latha Shanmugam for her Masters Degree on CFD in university of Leeds UK.
