Biosketch
Dr. Khuller's research interests include studying planetary ices, surface processes and atmospheres using a combination of numerical modeling, remote sensing data (Visible/Near-infrared, Thermal Infrared, Radar, and Microwave wavelengths) and geological mapping.
Before joining APL-UW in late 2024, he was a postdoctoral researcher at the Jet Propulsion Laboratory, where he gained experience with NASA flight hardware development and testing for thermal infrared instruments, CubeSat electric propulsion, and mission operations software.

On Earth, solar radiation can transmit down to multiple metres within ice, depending on its optical properties. Organisms within ice can harness energy from photosynthetically active radiation while being protected from damaging ultraviolet radiation. On Mars, the lack of an effective ozone shield allows ~30% more damaging ultraviolet radiation to reach the surface in comparison with Earth. However, our radiative transfer modelling shows that despite the intense surface ultraviolet radiation, there are radiatively habitable zones within exposed mid-latitude ice on Mars, at depths ranging from a few centimetres for ice with 0.01–0.1% dust, and up to a few metres within cleaner ice. Numerical models predict that dense dusty snow in the martian mid-latitudes can melt below the surface at present. Thus, if small amounts of liquid water are available at these depths, mid-latitude ice exposures could represent the most easily accessible locations to search for extant life on Mars. |

Life could exist on Mars in shallow meltwater pools below icy surface, study suggests UW News Scientists have yet to find evidence of life on Mars, but a new study suggests microbes could find a potential home beneath layers of ice known to exist on Mars’ surface. "If we’re trying to find life anywhere in the universe today, Martian ice exposures are probably one of the most accessible places we should be looking," said lead author Aditya Khuller. |
