Our Research
With the vast functional and metabolic diversity, microorganisms are integral to all the earth’s ecosystems; however, they change constantly throughout time and space. Meanwhile, the intensive human activities and global climate changes pose great challenges and complications for the understanding of their dynamics and the quantification of their roles in contributing to ecosystem functions and health. Hence, my research has aimed to explore the roles that microorganisms play in adapting to and mitigation of global changes. using the combination of classical techniques (qPCR, amplicon sequence, isotopes), state-of-the-art omics (metagenomics, metatranscriptomics, and metabolomics), and bioinformatic tools (high-performance computing, Python, snakemake, R program).
To be specific, my research is in the interface among Microbial Ecology, Bioinformatics, and Environmental/Soil Science in the changing world, and spans two directions:
(1) Community/restoration ecology--an assembly of the soil microbiome in diverse ecosystems and their response (resistance and resilience) to the changing environments;
(2) Microbial evolution and diversification--evolution and diversification of microbiome related to nitrifiers and denitrifiers, and their controls on global nitrogen cycling and greenhouse gas emissions, as well as the links to soil fertility and health.

Sabita Ghimire (Postdoc)
My research interests are focused on environmental microbial diversity and the physiological activities of environmental microbes. My Ph.D. research focused on the ecophysiological characterization of ammonia-oxidizing microbes. I also acquired expertise in identifying microbes through molecular tools like PCR, cloning, and Sanger sequencing. In addition, I experienced shotgun sequencing and bioinformatics analysis.

Nikky Omole-Ohonsi (PhD student)
Microbiology has always fascinated me, drawing me into the world of these seemingly “invisible organisms” and their profound impacts on our world. This passion led me to pursue a bachelor’s degree in microbiology, where I researched characterizing microbial communities found in cassava roots and their impact on human health. Currently, I am focused on nitrogen fixation dynamics in corn and soybean cropping systems in St. Louis, Missouri. Using molecular analyses, I examine the differences in nitrogen fixation rates and the abundance of nitrogen-fixing genes (nifH) in these two cropping systems. Other than research, I enjoy movies, dancing, and exploring new places with friends.

Hannah Hellmeier (Undergrad student)
Hi, I am a junior here at Saint Louis University studying Spanish and Forensic Science on the Pre-med track. I am passionate about the environment and am on the e-board for Ecology Club and Green Billikens. I enjoy learning about how humans and climate change are impacting the environment at the microbial and microscopic levels, and I look forward to researching the relationship between the two. In my free time, I enjoy hiking, reading, and watching The Big Bang Theory.
