    Many years of space instrument hardware development and remote sensing experience with direct contributions to the following NASA flight programs: Pressure Modulated Infra-Red Radiometer (PMIRR) on Mars Observer; Composite Infra-Red Spectrometer (CIRS) on Cassini; Gas and Aerosol Monitoring Sensor-craft (GAMS); Stratospheric Aerosol and Gas Experiment III (SAGE III) and James Web Space Telescope (JWST). Currently is the principal lead for the Compact Ultraviolet to Visible Spectrometer (CUVIS) on the DAVINCI Mission to Venus, to be launched in 2029.

    Research Interests

    Infra-Red Radiometry and Spectroscopy

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

    Net Flux Energy in Planetary Atmospheres

    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

    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. 

    Current Projects

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

    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

    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.

    Ice Particle Counter for Ocean World Plume-Flyby Missions, FY23 IRAD, Principal Investigator

    Develop an enabling technology that will count water-ice particles while flying through the plume of Enceladus or Europa. 

    Ultra-Violet Detector Innovation for Raman Exploration and CharacTerization (UV-DIRECT) of Ocean Worlds, NASA ROSES PICASSO, Co-Investigator

    Ultra-Violet Detector Innovation for Raman Exploration and CharacTerization (UV-DIRECT) of Ocean Worlds enables the identification of minerals, volatiles, organic molecules, biopolymers, water, and other hydrous phases in planetary materials with the added bonus of Raman spectroscopic imaging. 

    RAMS: RAman-Mass Spectrometer for planetary exploration, NASA ROSES PICASSO, Co-Investigator

    Raman-Mass Spectrometer (RAMS) instrument suite incorporates laser desorption/ ionization mass spectrometry (LDMS) and micro Raman microspectroscopy imaging (μRS) into a compact instrument package with shared resources realizing size, weight and power (SWaP) savings over two separate instruments, while simultaneously enabling comprehensive sample analysis capabilities transcending those of either technique alone.

    Quantum efficiency and noise performance of back-side illuminated CMOS detector arrays for future planetary ultra-violet to visible hyperspectral imagers, FY23 IRAD, PI

    Measure quantum efficiency and noise performance characterization, from deep ultra-violet (UV) to visible (Vis) to near infra-red (NIR), of a Teledyne e2v back-illuminated CIS115 CMOS image sensor.
