Dustin D. Heese, M.S. 
Geologist & Astrobiologist

My research has focused on the detection of potential biosignatures and their preservation conditions within ironstones (>15 wt.% [Fe]), in conjunction with the elucidation of oolitic ironstone mineralogy, formation mechanisms, and diagenetic conditions. This research expands the understanding of these enigmatic deposits on Earth and establishes targets and criteria for detection of life on Mars.

Supported by the NASA Astrobiology Planetary Instrument Concepts for the Advancement of Solar System Observations (PICASSO) program grant and KU Endowment, this research facilitated my role as a primary operator in the Earth, Energy, and Environment Center's Raman Spectroscopy Laboratory. There, I utilized a Renishaw inVia Reflex Spectrometer and Illuminat IR II FTIR system, while training and supervising student researchers in their use. I have conducted further research at the University of Kansas Fluid Inclusion Geochemistry Laboratory and the Microscopy and Analytical Imaging Research Resource Core Lab.

Through this research I have developed skills in: Raman spectroscopy of crystalline solids and carbonaceous materials, sedimentary petrography, fluid inclusion geochemistry and microthermometry, scanning electron microscopy and energy-dispersive X-ray spectroscopy, and thin section preparation. As part of this research I conducted independent field work in AL.

I have additional primary research in Mississippian quartz geodes and I have collaborated on investigations of nanoparticle hematite, iron meteorites, garnets, stone tools, and oil-bearing deposits.

I have 7 years of experience as the Geoscience Laboratory Technician at Johnson County Community College. My role encompasses the logistical management and equipment calibration for the laboratories and courses. I am responsible for annual procurement budgets and the maintenance of diverse instrumentation, from spectrophotometers, DO meters, and air quality monitors to groundwater models, stream activity tables, and an augmented reality sandbox. I maintain HAZWOPER certification and oversee small scale hazardous materials management and lab safety.

I have broad academic and field foundations, ranging from petrology, biogeochemistry, geochemistry, and carbonate systems to groundwater contaminants, contaminated site assessment, and environmental site safety and operations. My training includes field courses in Spain, the Bahamas, CO, UT, WY, OK, MO, and KS, alongside specialized work in Raman spectroscopy, paleontology, ichnology, paleoclimatology, soil geomorphology, and fluid inclusion geochemistry.
