ENVR3140: Aquatic Ecosystem Services

Research Interests

The Collins Lab works to understand the origin, evolution, distribution, and function of microorganisms in the cryosphere, including bacteria, archaea, algae, protists, fungi, and viruses. Using high-throughput and real-time sequencing of DNA, we conduct metabarcoding, genomics, metagenomics, transcriptomics, and metatranscriptomics. We also develop software for the analysis and visualization of large datasets using machine learning approaches.
