Ozan holds an MS in molecular biology and genetics from Izmir Institute for Technology and a PhD in evolutionary biology from the Max Planck Institute. He continued his postdoctoral research at the Ratcliff Lab, where he began a long-term evolution experiment to explore the effect of oxygen on multicellular evolution. Ozan currently works as a research scientist, leading our multicellular long-term evolution experiment (MuLTEE), and teaches courses for both graduate and undergraduate students at GT.

After completing a genetics major and astronomy minor from the University of Maryland, Tony pursued his Ph.D. at Duke University under the guidance of Dr. Nick Buchler. His research work there focused on studying the relationship between the yeast metabolic cycle and the cell division cycle. With an avid interest in astrobiology, he later joined the Ratcliff lab at Georgia Tech, where he studies the evolution of multicellularity and the forces that shaped it. His research interests include examining the various mechanisms employed by life to overcome oxygen limitation on multicellular sizes, such as phototrophy and the origin of oxygen-binding globin proteins, investigating the impact of chaperone proteins on multicellular evolution, and exploring the field of synthetic biology. Additionally, he is an enthusiastic reader of scientific papers and also volunteers at the university community garden.

Dung completed her Bachelor’s degree in Biotechnology at the University of Science, Ho Chi Minh City, Vietnam, and her Master’s degree in Biology at Georgia State University, Georgia. After joining the Ratcliff Lab in 2021, she has been studying the role of heat shock proteins HSP90 in the macroscopic adaptation of snowflake yeast through a replay evolutionary experiment. In her free time, Dung enjoys photography, travel, and good food.

Autumn received her undergraduate degree in Environmental Sciences from Virginia Tech in 2020. She is now a Ph.D. student in the Biology Program at Georgia Tech. Her research interests include the evolution of phototrophy and the role of nascent life cycles in the subsequent evolution of multicellularity. Outside of the lab, her interests include: working out, tending her garden, and exploring the city. Her favorite show is Avatar the Last Airbender and her favorite type of food is seafood.

Chris completed his BS in neuroscience with a minor in astronomy at the University of Maryland in 2014! There, he worked with Dr. Wade Winkler to understand the RNA binding domain called ANTAR and its associated proteins. Currently, he has joined the Quantitative Biosciences Ph.D. program where he co-advised with Dr. Hammer. He studies the unique evolutionary patterns that arise when bacteria encode the Type 6 Secretion System. Chris enjoys climbing, making things, and reading books in his spare time.

Emma is a QBioS Ph.D. student co-advised in the Ratcliff and Yunker Labs, working on the physics of the evolution of multicellular life. She studied physics and political science as an undergrad at MIT and is originally from Wilmington, North Carolina.

Sayantan finished his BS-MS dual degree at IISER-Pune, India in 2022, where he worked on the interaction of bottlenecks and the evolution of asexual populations at the Population Biology Lab. He is now a QBioS Ph.D. student at our lab where he is interested in studying the life history of nascent evolving multicellular yeast and the evolution of cell differentiation. In his spare time, he loves to paint, photograph, and play Dungeons and Dragons.

Luis Felipe is from Mexico City, México. He graduated from the National Autonomous University of México, where he studied Genomic Sciences. Before joining the QBios PhD program, he did a year internship in the lab during which he began studying trade-offs that have evolved in the Snowflake yeast. In his spare time, he likes to read science fiction books, take photos of nature, and play video games. Interestingly, he doesn’t like spicy food or avocados.

Hikaru completed his Bachelor of Science in Biological Science from Kyoto University in 2023. Currently, he is pursuing a Ph.D. in Biology at Georgia Tech. In our lab, his research focuses on the impact of lipid transportation during multicellular evolution. He enjoys listening to music, watching movies, and indulging in delicious food.

Gillian is a third-year Biology student at Georgia Tech with a minor in Japanese. She is currently working with Dung, Hikaru, and Dr. Bozdag on a project titled “Emergent Gene Expression Patterns in S. cerevisiae Under Anaerobic, Mixotrophic, and Aerobic Regimes”. In her free time, she loves to crochet, sew, draw, and listen to music. Her favorite bands are Sleep Token and Spiritbox.
