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.

Staff & Postdocs

Andrew Ahearne (Asheville, North Carolina)
Nicknames: "Andrew", "The-Young-Guy", "Mr. Anime"
Ph.D. Pharmacognsy, University of Mississippi [2024]
B.S. Chemistry, University of North Carolina, Asheville
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

Graduate Students

Noah Kilonzo (Nairobi, Kenya)
Nicknames: "Nuhu"
Ph.D. student
B.S. Biology, Ankara University, Ankara, Türkiye
Email:

I joined the Hom lab in January 2024 and am doing research into algal-bacterial-plant mutualisms, particularly focusing on how these interactions play out during seed germination and establishment. I’m passionate about science and service and I’m curious as to where this will take me! I also enjoy meeting new people, singing and reading books (was a librarian in high school)!.
Keywords: Seed-endomicrobiome, plant-microbe interactions, bioinformatics, coevolution, education, operatic singing


(Thomas) Eli Null (Corinth, MS)
Nickname: "Eli," "Null value," "the Gentle Giant"
Ph.D. student
B.A. Biology, University of Mississippi
Email:

What’s up? I’m Eli Null. I was an undergraduate researcher in the lab and liked it so much, I will continue on in the Ph.D. program in Fall 2025. My research here centers around the experimental evolution of synthetic fungal-algal mutualisms. My “mad scientist” work, I hope, will contribute to advancing the field of evolutionary biology and sustainable efforts in large scale alga-culture systems. Outside of the lab, I enjoy playing video games, tailgating with friends and family, and learning about life and all the things it provides.
Keywords: coevolution, franken-lichens, algaculture, video games, tailgating

My name is Danh Nguyen, and I am excited to be a part of the Hom lab. I am currently on the kefir team; I joined the lab due to my interest in symbiotic relationships and microbiomes (very general, I know) and to gain lab experience. On campus, I am a part of the Sally McDonnell-Barksdale Honors College, the Luckyday Foundation, and Active Minds. I also work as a teaching assistant for the Department of Chemistry and Biochemistry! On the weekends, I often take trips outside the city to explore the various Trader Joes, zoos, and science museums that Oxford lacks :) In my limited free time, I campaign for the installation of a Target in Oxford.

I’m a proud transfer student from Mississippi Gulf Coast Community College. I love animals so much that my long-term goal is to become a veterinarian specializing in feline medicine. I have a particular affection for cats, and I have two of my own—Beans and Bosco. In addition to my passion for animals, I also enjoy conducting research in the lab. My current projects involve a coevolution experiment and a culture-based study of microbial communities. When I’m not in the lab, I like to visit friends or work at the animal hospital. I also volunteer at various shelters and veterinary clinics.
Keywords: co-evolution, synthetic communities, algae, cats, animal love

Class of 2027, University of Mississippi (B.A. Biology and Public Policy Leadership; minor: Southern Studies)
Email:

Hi y’all! My name is Emerson Morris, and I am proud to be a part of the Hom Lab. I am particularly passionate about the overlap of STEM and politics, particularly in the realms of conservation, the farming world, and sustainable agriculture in the American South. Outside of the lab, I find great joy in tea making and tasting high quality brews. In my incredibly limited and highly sought-after spare time, I enjoy hiking, listening to bad 90’s rock music, reading, and being active in the UM campus community. I am excited to ask a million questions and learn as much as possible!

Class of 2026, University of Mississippi (B.A. General Business, minors: Biology, Chemistry)
Email:

After Ole Miss I am planning on attending medical school and becoming a doctor (no idea what kind yet). I am working on the marine polyculture and sloth algae projects. I am hoping to find ways to create better treatments for patients from a research perspective instead of a clinical one. I am also excited to begin working on my Honors thesis. I love watching any sport, playing pickleball at every hour of the day, and hanging out with my friends.

Nicole Hinkley-Kellum (she/her) (Water Valley, MS)
Nickname: "Nicci," "The Chef"
Class of 2028, University of Mississippi (B.S. Biology (Organismal))
Email:

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.

When I’m not in the lab, I’m singing for Pinelake Church, playing pickleball, or cooking up something delicious in the kitchen. Off campus, I love hanging out with friends, watching Criminal Minds, and looking for my next adventure or creative project. In the future, I plan to continue my studies in biology at graduate school, focusing on cellular or molecular biological research.

Hey y’all, my name is Senton and I am excited to be a part of the Hom Lab. I will be researching and surveying lichens in Mississippi, particularly lichens in the Delta, Desoto, and Holly Springs National Forests. Outside of the lab, I am involved in RebelTHON, The Big Event, and Mortar Board Honor Society. In my spare time, I enjoy watching sports (especially baseball and college basketball), cleaning my fish tank, and running on the South Rec trail and Lamar Park. After graduation, I plan on continuing my studies in medical school to become a doctor of whatever specialty I will choose.

Email:
Beautiful summer day, huh? Well...maybe not in Oxford, Mississippi, ha! Despite the intense humidity, Oxford does have some good things, though: the Hom Lab and the pickleball courts. I joined the Hom Lab to pursue my interests in microbes and their interactions, specifically at the molecular level. My current project revolves around microbiology, RNA expression, and zinc chloride. Someday, I want to be a principal investigator who leads a successful research program. Some hobbies outside the lab include pickleball, working out, Clash Royale, and hanging out with friends.
