About
R. Bhartia is a pioneering scientist whose career sits at the dynamic intersection of astrobiology, spectroscopy, and planetary exploration. Best known for their central role in developing the SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) instrument aboard NASA's Perseverance rover, Bhartia has made transformative contributions to humanity's search for signs of ancient life on Mars. The SHERLOC investigation — Bhartia's most cited work with 237 citations — represents a landmark achievement in robotic planetary science, combining deep ultraviolet Raman and fluorescence spectroscopy to generate spatially resolved chemical maps of Martian surfaces. Their subsequent work on SHERLOC's calibration targets further extended the instrument's utility, bridging scientific operations with public outreach and future human exploration planning. Beyond Mars, Bhartia has advanced autonomous biosignature detection in extreme terrestrial environments and developed novel methods for cosmic ray removal in Raman hyperspectral datasets. Their long-running collaboration with Photon Systems and JPL on deep-UV standoff sensors for detecting chemical, biological, and explosive materials underscores a career defined by translating cutting-edge spectroscopic technology into real-world exploratory tools. With nearly 400 cumulative citations, Bhartia's work continues to shape the frontier of astrobiology instrumentation.
