Lavanya Periasamy

As a postdoctoral researcher at JPL, I am involved in the prelaunch characterization of two thermal infrared spectrometers (0.2 – 54 um) for the PREFIRE CubeSat mission. Previously, my doctoral work focused on the end-to-end system design of a low cost 118.75 GHz scanning temperature sounding radiometer for CubeSat missions. Prior to pursuing my PhD, I worked as an engineer at Qualcomm where I developed objective quality measurement techniques for music/voice by application of perceptual algorithms.


Education
  • Ph.D. (2019), Electrical Engineering, University of Colorado at Boulder, Boulder, CO.

Research Interests

My interests lie in understanding challenges faced and developing techniques for the design, implementation and calibration of precision remote sensing radiometers/spectrometers (across the electromagnetic spectrum) built particularly for small satellite missions that further earth or planetary science studies. 


Projects

PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) Icon PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment)
Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) will quantify the radiative processes effected by changing temperatures in the Arctic.
