CV

Trained as a biophysicist with a bent towards physical chemistry, my current research focuses primarily on understanding how microbes adapt to live together symbiotically, particularly at the level of genes and metabolism. My research interests over the years have been (and remain) eclectic, but there is actually some rhyme and reason to them (see the research tab). More about Erik here.

Email:

Hi, I'm Andrew, maybe one day I'll be a real doctor. My primary research is focused on two goals: 1) heterologous expression of exciting and secret BGCs (shh) and 2) the creation of high-yield expression strains of model microbes. In addition, I'll probably be involved in some of the lab's new work on Chlamydomonas and biocrusts—oh fun! In my free time, I enjoy growing exotic fruiting plants from around the world. That's my secret for keeping me looking as young as I do. Keywords: cloning, heterologous expression, biosynthetic gene clusters, bacteria, biocrusts, exotic plants

Email:

I will be joining the Hom lab as a Ph.D. student in January 2025. Working on understanding microbial interactions at the molecular level is always exciting and fun for me. I hope to work on underestanding microbial interactions and their co-evolutionary histories both in the environment and in relation to the human gut. I will likely work on both the lab's projects on biocrusts and kefir. In particular, I want to explore more of the molecular genetics of viruses that are a component of these microbial communities. If all goes well, findings from these projects should contribute to finding answers to some basic questions related to human health and the origin of life. In my spare time, I like to explore new places and photograph nature and landscape scenes.
Keywords: microbial interactions, coevolution, viruses, biocrusts, kefir, gut microbiome, metagenomics, photography

Class of 2026, University of Mississippi (B.A. Business)
Email:

My passion for medicine has driven me to pursue a career as a doctor, and I'm currently working towards that by diving into various areas of research, particularly participatory systems mapping. This area of study fascinates me because it allows me to explore complex systems and how different elements interact, which I believe will be incredibly valuable in understanding the intricacies of healthcare. When I'm not focused on my studies or research, you'll most likely find me outdoors. I have a deep appreciation for nature and love spending my free time hiking, camping, or simply exploring the natural world around me. These outdoor activities not only keep me active but also provide me with a sense of peace and balance, which is essential as I navigate the challenging path to medical school.

Hey there, I’m Nicole. I’m thrilled to be on board with the Lab this year, working with the team studying kefir and gut health. I’m a returning student, making a shift back into Biology from the culinary world by getting “back on my B.S.”, if you will, with an emphasis in Organismal Biology. I joined the kefir lab as part of my pursuit to finish my degree, doing what I really love: assisting with tedious, endless, scientifically-based exploration. I’m here to shift my real-world experience into supporting the goals of the lab, and gain all the experience it has to offer in return. I’m into chaos gardening, thrifting, making and eating food, deep cuts of old music, and making surreal collage art.
