Lab Members

LAB MANAGER

Bryan King

Bryan earned his Ph.D. in Cellular and Molecular Biology from Baylor University, specializing in Vector Biology with a focus on mosquito genetics, diapause, and bacterial interactions. His doctoral research explored the genes regulating overwintering survival in Culex pipiens mosquitoes and the impact of Wolbachia bacteria on the diapause phenotype, contributing to insights into vector control strategies.

As Laboratory Manager for the Greathouse Lab at Baylor University, Dr. King oversees lab operations, ensuring efficient research workflows and managing IBC research compliance. He mentors undergraduate researchers, fostering their interest in biological research and training the next generation of scientists and science-literate professionals.

POST-DOCTORAL FELLOWS

Ankan Choudhury

Kolkata, India

Ankan earned his Bachelor’s and Master’s degrees in Pharmacy from Jadavpur University, and his PhD at Baylor under the guidance of Dr. Chris Kearney. His current research involves 1) exploring key bacterial markers in the gut microbiomes of colon cancer patients and identifying key dietary indicators that are crucial in maintaining a healthy gut microbiome for such patients which will improve their response to chemotherapy/ immunotherapy and increase survivability, 2) understanding the role of indole and indole-derived metabolites in the biofilm formation procedure of key species of gut microbiome and their influence on turning the species into an opportunistic pathogen, and 3) exploring the role of nucleic acid load of outer membrane vesicles (OMVs) of pathogenic strains Bacteroides fragilis and determining the fate of such OMVs and their cargo upon entering host cells, using click-chemistry aided fluorophore tagging.

Maysen is interested in exploring the role of the microbiome in carcinogenesis and how to mitigate this process.

Julie Fazekas

Lake Forest, CA

Julianne received her undergraduate degree in Biology from Biola University in 2024 where she researched the impact of natural compounds on colorectal cancer (CRC) progression. Continuing her education, she joined the Greathouse Lab in pursuit of her Ph.D. in Biology. Julianne is fascinated by the gut microbiome’s influence on the progression and development of CRC and is eager to investigate this relationship further.

Undergraduate Students

James Lotter

Dover, NH

James is a senior Science Research Fellow with a concentration in biochemistry and minor in nutrition. He became interested in the role of diet on health during a weight loss journey of over 100 lbs and became fascinated with the world of the microbiome in the process. This curiosity is satisfied through the Greathouse Lab, and he looks forward to learning more about the topic each day. Future plans include pursuing a Ph.D. to explore his interests of research and medicine with emphases on gastroenterology and nutrition.

Alli Barton

Missouri City, TX

Alli is a senior University Scholar with a concentration in Biology and minors in Medical Humanities and Spanish. Alli became interested in the Greathouse Lab and microbiome research after acting as a research participant in the Vitamin D Microbiome study. She hopes to learn more about probiotic development and cancer prevention through her work within the lab. After graduating from Baylor, Alli plans to attend grad school and become a physician assistant.

Jessalyn Hawkins

Freeport, MI

Jessalyn is a senior University Scholars major with concentrations in biology and neuroscience. She is fascinated by the intricate relationship between the gut microbiome and colorectal cancer. She hopes to continue to learn about the process of scientific research. With aspirations of pursuing an MD/PhD program, Jessalyn aims to merge her passion for research with clinical practice to contribute significantly to the field of medicine.

Gregory Zaharas

Denver, CO

Gregory is a senior Cell and Molecular Biology major and history minor. Gregory’s future plans are to go to medical school.

Dana Azzouka

Amman, Jordan

Dana is a junior University Scholar with a secondary major in Biology on the pre-medical track. She previously conducted research on a method that prolongs the shelf life of fruits that are essential for human nutrition, which had an implication for food security during the COVID-19 pandemic. This stimulated her to take a step further and investigate the interplay between dietary factors and carcinogenesis. In her future endeavors, she intends to pursue an M.D./Ph.D. program to integrate her research pursuits with her medical aspirations.

Jeffrey Marsiglia

Jeffrey is a junior Health Science Studies major with a focus on pre-medical studies. His passion for microbiome research was sparked by his cousin’s work in the field, inspiring him to explore the intricate relationships within the gut microbiota. Through the Greathouse Lab, Jeffrey hopes to deepen his understanding of how these microbial interactions influence human health. In the future, Jeffrey plans to attend medical school, where he hopes to integrate his research interests with clinical practice.

Kaitlin Wilbur

Kaitlin is a junior biology major with a concentration in cell and molecular biology on the pre-med track. She has always been intrigued by the development of cancer, and specifically how diet can contribute to various cancers. She is excited to further her understanding of the relationship between the gut microbiome and how its environment can play a role in colorectal cancer. After graduation she plans to attend an MD program to fulfill her medical ambitions.

Emma Kenyon

Emma is a senior majoring in Biology, with minors in Biochemistry and Studio Arts. Her interest in how diet affects the gut began early, influenced by seeing chronic disease in her family.
