- Published two papers geometrically visualizing simple sun-tracker mechanisms for mirror-fields of arbitrary contours- Filed patent application for another, simpler mechanism for mirror-fields of arbitrary contours- Carried out mathematical modelling and computer simulations on various shapes and configurations of concentrators and concentrating systems- Derived mathematical equation for mirror to 'correct' spherical aberration and produce point-focus- Carried out mathematical and extensive computer studies of various (parameterized) shapes of such correcting mirror at Tata Institute of Fundamental Research (TIFR) Mumbai- Have conceptualized many more promising concentrator designs- Seeking partners to develop prototypes for possibe commercialization, possibly with joint IPR. Note that concentrated solar is increasingly being used in solar PV in addition to more traditional applications in solar thermal

- Headed many top-level strategic planning committees, including those for Citizen’s Charter, Vision Document, and Training Policy for the entire Income Tax department- Formulated crucial statutory ‘tax audit’ process, mandating pre-filing tax audits of large tax-payers by independent accountants, thereby improving compliance and providing tax-payers an indicative assessment of their tax liabilities and allowances- Led Indo-Canadian project team that developed an early-warning system for detection of 'suspect' tax returns. The project resulted in better determination of depatment revenue at risk and serves as a deterrent to tax evasion- Was involved in progressively wider areas of responsibility through career including computerization of tax data and processes and successfully representing Income Tax department in Income Tax Appellate Tribunal. Superannuated as head of Income-tax Department in Delhi
