Michalski Research Group

  • Denmark Purdue-University of Copenhagen collaboration
    Wendell Walters will be conducting research at the Department of Chemistry, University of Copenhagen during the summer of 2015. He will be using their photochemical chamber to understand isotope effects arising during the cycling of nitrogen oxides in the atmosphere. Funded by the National Science Foundation graduate fellowship program.
  • N2O Project Purdue-Los Gatos collaboration
    Ben Wilkens will be collaborating with Los Gatos Research to integrate their new off-axis laser N2O isotope analyzer with the bacteria method for NO3- δ15N and δ18O analysis and conducting field analysis to analyze δ17O emitted from soil. Funded by the USDA small business grant program.
  • Yellow River Purdue-Beijing Normal University collaboration
    Prof. Michalski will be traveling to China in May of 2015. He will be collecting samples from the Yellow River to assess sources of N pollution. He will also be teaching a short course on mass independent isotope effects in nature at the Chinese Geosciences University, Beijing as the invited guest of Prof. Wenshen Ge.
  • New Zealand Purdue-GNS-NIWA collaboration
    Tanya Katzman has been awarded a East Asia and Pacific Summer Institutes (EAPSI) fellowship from NSF. She will be working with the New Zealand’s Geology and Nuclear Science center (GNS) and the National Institute of Water and Atmospheric Research (NIWA) and will be studying sulfur oxidation chemistry occurring off coastal New Zealand over the summer of 2015.
  • Pakistan New project!
    Studying nitrate groundwater pollution in rural Pakistan. The United States Agency for International Development (USAID) and the Higher Education Commission of Pakistan has funded a joint project between Purdue and Abdul Wali Khan University-Mardan studying nitrate pollution in rural wells in the Thar Desert region of Pakistan.
