Dr Yano is a Research Assistant Professor in the Department of Ecology at Montana State University. Her expertise include soil ecology and biogeochemistry.

Paul Szejner, PhD – Postdoctoral Researcher

Paul Sjezner_headshot

Dr. Szejner received his PhD in 2017 from University of Arizona and is currently a postdoctoral researcher. His expertise include dendrochronology, stable isotope biogeochemistry, and forestry. He is currently researching the mechanisms driving carbon and water fluxes in forested regions from seasonal to centennial time scales.


Justin Martin – PhD graduate


Justin is National Science Foundation Graduate Research Fellow and just defended his PhD in May 2018. Justin studied how factors such as local microclimate and hydrology impact tree growth and water use. After graduation, he will be working for the USGS Northern Rockies Mountain science Center.


Claire Qubain – MS Student

hulab_claire_qubain_bw4Claire is a PhD student who joined the lab in summer 2015.  She is examining how nitrogen availability is mediated by topography and snowpack at Lubrecht Experimental Forest.  Claire is particularly interested in researching how human activity alters nitrogen cycling and, in turn, drives environmental change.

Tim Clute – MS Student


Tim is a PhD student who joined the lab in 2015. His research will use tree rings to determine how western conifers have responded to historical changes in climate and water use, and how we can use this information to predict responses to climate change.


Kinzie Bailey – MS Student

Kinzie is a Masters student who joined the lab in 2017. She is conducting a study to determine the difference in water use between juniper and willow and the effects of removal on stream water availability.
