    Noah Molotch

    Principal Investigator

    My research and teaching interests are focused on mountain hydrology and fostering a diverse and equitable scientific community. My research projects utilize ground-based observations, remote sensing, and computational modeling to obtain comprehensive understanding of hydrological processes; in particular the distribution of snowmelt, soil moisture and streamflow.  Studies relating fluxes of water and carbon are also a focus of my current projects - in particular carbon cycling in montane forests.  I mentor a diverse group of scientists and seek collaborations with individuals with unique perspectives and life experiences.
