Lab Openings

Research Interests:

Synthetic ecology, evolution of symbiosis and mutualism, fungal-algal associations, evolution of plant-microbe interactions, microbial and chemical ecology of marine polycultures (including fungi and cyanobacteria), microbial ecology of fermented foods, sloth microbiome, genetic basis of natural product production, biological soil crusts, and biological approaches to industrial waste valorization.

Joining the Lab:

If you are interested in pursuing an M.S., Ph.D, or postdoctoral experience with Dr. Hom, please contact him directly via email. Undergraduate students interested in research projects are also encouraged to speak to Dr. Hom directly (do not be shy, he does not bite). Minority students, women, and high school students are especially encouraged to explore research opportunities in the lab. The lab operates with a team mindset of working hard, playing hard, having fun, and doing the best cool science we can.
