Instrumentation Consultant / Critical Data Delivery Specialist

Zach oversees Beaded Stream’s field logistics, provides customer support and develops remote temperature monitoring solutions. He comes to Beaded Stream with a strong background in field-based, hydrologic research. At the University of Montana, Missoula, he earned an M.A. in Geography for his study of rock glacier distribution, mapping and paleoclimatic reconstruction as well as an M.S. in Geosciences for his work in snow hydrology and seasonal snowmelt modeling.

Zach spends as much time exploring remote locations as he does studying them and enjoys the opportunity to streamline field data collection processes with Beaded Stream’s clients. Originally from New Mexico, Zach has lived in Colorado and Montana before moving to Anchorage. If he could have skied from there to here, he would have.
