National Park Service Scientists


Cathleen Balantic, PhD

I specialize in bioacoustics at the Natural Sounds and Night Skies Division. I'm interested in what biological sounds can teach us about animal distributions and trends through time in the parks. Knowledge of biological sounds can inspire park visitors and foster broad insights about the impacts of management action, land use, and climate change.


Davyd Betchkal

I joined the Natural Sounds and Night Skies Division after five years as a Soundscape Technician at Denali National Park and Preserve. I am tasked with preserving the acoustic and photic resources of the Alaska region parks through science, planning, and outreach.


Emma Brown, M.S.

I am an Acoustical Resource Specialist at the Natural Sounds and Night Skies Division. I coordinate the measurement of acoustic conditions in National Parks, as well as analysis and reporting for these data. My favorite natural sound is the 'U'au (Hawaiian petrel).


Damon Joyce

I am a Physical Scientist with the Natural Sounds and Night Skies Division. I develop hardware and software to collect acoustic data in National Parks, and work with other parks to help them conduct their own monitoring.


Katie Nuessly, M.S.

I work as an Ecologist with the NPS Natural Sounds and Night Skies Team. I use computer models to study how noise pollution affects national park visitors and wildlife. Noise models generate complex results that include multiple metrics, making it difficult to directly apply to land management actions. Therefore, I also develop science communication products, like infographics, to effectively communicate the important results relevant to management alternatives.


Ashley Pipkin, M.S.

I am a Resource Specialist for the Natural Sounds and Night Skies Division for the Pacific West Region of the National Park Service. I am responsible for synthesizing soundscape and photic data in some of the most beautiful landscapes in the world. My favorite natural sounds come from mountain streams and the accompanying life that surrounds them.


Jeremy White, M.S.

I am a Physical Scientist with Natural Sounds and Night Skies Division. My main focus within the division is night sky quality assessments in parks, instrument development and calibration for sky brightness measurements, and assisting parks with planning documents related to night sky resource protection.

Graduate Student


Casey Lee

I'm broadly interested in the effects of land use and habitat fragmentation on wildlife behavior. Here at CSU, I work with the the Sound and Light Ecology Team and the Angeloni, Wittemyer, and Crooks labs to understand the impacts of noise on black-tailed prairie dogs. I'm also interested in spatial and simulation modeling, habitat assessment methodologies, science education, and the perceptions and politics of science. My fascination with sound extends beyond research. I enjoy audio engineering and battling my nefarious alter ego, a classically-trained fiddle player who flirts with mandolin, guitar, and old-timey sensibilities.

Contact one of the CSU faculty team members via their personal website if you are interested in joining our team as a graduate scientist.
