Research in the Guo group focuses on tuning and understanding electrochemical interfaces. Leveraging our expertise on nanomaterial synthesis, electrolyte design, electrochemical analytical tools, and in situ vibrational spectroscopy, we aim to precisely control and understand electrochemical interfaces at molecular level. Eventually, our goal is to unlock new insights into environmentally important processes, such as the electrochemical conversion of atmospheric CO2 and nitrate pollutants to value-added products.

Lukas is a coastal wetland ecosystem/landscape ecologist with wide-ranging interests that generally focus on understanding how climate and anthropogenic forces are impacting coastal wetlands, particularly with respect to carbon dynamics. Lukas' research involves using both field-based and remote-sensing based methods in order to test research questions at multiple spatial scales and provide upscaled estimates of ecosystem processes. 
 

I am interested in the remote sensing of blue carbon ecosystems and climate change ecology. My research is dedicated to quantifying changes in mangrove forest coverage along with the dynamics of their carbon storage and fluxes. To achieve this, I utilize a combination of remote sensing, machine learning, and ecological modeling techniques.
