Research Interests


Infra-Red Radiometry and Spectroscopy

Solar System: Remote Sensing

Development of infra-red radiometers and Fourier transform spectrometers for remote sensing of planetary atmospheres.


Net Flux Energy in Planetary Atmospheres

Solar System: Uranus

Development of advanced net flux radiometers for studying the atmospheric (thermal) structure of planetary atmospheres, in particular to, (i) determine the planet’s atmospheric heat balance and (ii) determine the planet’s tropospheric 3-D flow.


Time Resolved Raman and Photoluminescence Spectroscopy

Solar System: Planetary surfaces

Development of instrumentation to carry out in-situ time-resolved Raman and photoluminescence (PL) spectroscopy, of samples collected from planetary regoliths, to discover, if present, the types and distribution of biotic and abiotic organic compounds, measure CHNOPS containing organics and minerals and correlate them to radiolysis processed and textural features. 


Non-Dispersive Infra-Red Gas Analyzer

Solar System: Comets

We are designing and building a Non Dispersive Infra-Red Gas Analyzer (NDIRGA) for the New Fontiers CAESAR project (Pre-Phase A), that uses a measurement scheme based on the Beer-Lambert Law. The NDIRGA is used to measure H2O and CO2 partial pressures between the SCS and GCS and uses two redundant 4-channel (quad) thermopile detectors with 2.7-μm and 6.6-μm H2O absorption band, 4.0-μm reference filter and 4.2 µm CO2 absorption band, each paired with redundant IR sources. Knowledge of the water vapor partial pressure will ensure that we avoid reaching the triple point of water (within the P-T range 3 Torr @ 268 K and 16 mTorr @ 218 K). The measurement uses a collimated pulsed IR light source focused onto the quad thermopile detectors with IR bandpass filters in front of them. The absorbed IR light on the thermopiles generate small thermoelectric voltages that are amplified and digitized by a multi-channel digitizer (MCD) ASIC. The 20 bit digitized signals from the MCD ASIC are communicated to the FPGA board in the MEB for further data processing.

Current Projects


Compact Ultraviolet to Visible Imaging Spectrometer (CUVIS) Technology Demonstration onboard the DAVINCI Mission to Venus, NASA Discovery Mission, Principal Engineering Lead

Remote Sensing

Design, build, test and validate a Compact Ultraviolet to Visible Spectrometer (CUVIS), an innovative dual-band dispersion and imaging spectrometer with spectral range 200–570 nm, that will complement the science obtained from DAVINCI's VISOR UV Camera. The spectrometer’s primary goal is to investigate radiative balance, cloud properties and chemistry of Venus’s atmosphere, address the vexing scientific problem of the unknown UV absorber(s) at the cloud tops; secondary goals include cloud top habitability, and to gain insight into slow rotating hot exoplanets by using Venus as a test case.


Modular Infrared Molecules and Ices Sensor (MIRMIS), ESA F-Class Comet Interceptor Mission, Science Associate

Comets

MIRMIS covers the spectral range 0.9 to ~25 μm and will map the ice, mineral, and gas composition ofthe target’s nucleus and coma and the distribution of surface temperatures on the nucleus.
