Stuart Grandly Lab

Our research examines how soil organisms interact with their environment to regulate ecosystem processes such as nutrient cycling, organic matter turnover, trace gas emissions, and productivity. This research encompasses multiple spatial scales and lies at the interface of soil ecology, biogeochemistry, and ecosystem science. While we use a range of fundamental laboratory methods, which include molecular chemical and microbiological approaches, we always have an eye towards applying our results to improve ecosystem processes and management.

  • Congratulations to Amanda Daly, who was named a finalist for the Presidential Management Fellowship (article in UNH Today: www.unh.edu/unhtoday/2018/01/soil-savior)
  • Andrea Jilling presented her research on the bioavailability of mineral-associated nitrogen at the annual conferences for the Soil Science Society of America and the American Geophysical Union.
  • Congratulations to former post-doctoral research fellow Jörg Schnecker for earning a FWF grant to study "Seasonal dynamics of microbial carbon sequestration." Stuart Grandy and Emily Kyker-Snowman helped author the grant.
  • PhD student Lauren Breza presented on the drivers of nitrogen distribution and retention across multiple SOM pools at ESA this summer.
  • Nell Campbell chaired her first session at AGU, on multiscale measurements and modeling of GHG emissions from livestock, grasslands, and croplands
  • Congratulations to former undergraduate researcher Katie Slebodnik, who was awarded the Outstanding Student award for Environmental Sciences this year. Katie will be moving on to a MS program in Jennifer Reeve’s Lab at Utah State.
  • PhD student Emily Kyker-Snowman presents her research on the MIMICS model and temperature sensitivity in microbial parameters at AGU in New Orleans this December.
  • Congratulations to former post-doctoral research fellow Tim Bowles accepted a position as Assistant Professor of Agroecology/Sustainable Agriculture at University of California, Berkeley. Tim begins his position July 2017 and will continue collaborating with the Grandy Lab on how cropping system diversification impacts soil organic matter, soil ecosystem services, and yield resilience.
