    • Brief Bio

    Dr. Melissa Ugelow is an analytical and atmospheric chemist interested in studying the complex atmospheric chemistry that results in organic aerosols and ice clouds in planetary atmospheres. During her Ph.D. work, she primarily experimentally studied the optical and chemical properties of organic aerosols relevant to planetary atmospheres. As a NASA Postdoctoral Program fellow in the Spectroscopy for Planetary ICes Environments (SPICE) laboratory, she experimentally studied organic ices relevant to Titan's stratosphere. Following her postdoc, she currently performs laboratory IR transmission spectroscopy on thin ice films composed of nitrile and hydrocarbon ices in order to quantify the chemical identification of Titan’s Composite Infrared Spectrometer (CIRS)-observed co-condensed stratospheric ice clouds, along with understanding their formation pathways and structural properties.
