Jessica Bains
Bio
I am an incoming first year PhD student in Dr. Christina Richards laboratory. I am from England, UK and first attended USF as an undergraduate student receiving my B.S. in Biology.
My path to getting to where I am today was very rocky but I learnt some very important lessons along the way especially to follow your passions. I took a few years working at a medical diagnostic laboratory in Pinellas Park and then moving over to become a teaching laboratory manager at USF.
I hope to work on understanding plant and microbial growth in stressful environments, with the goal of a career in astrobiology. Dr. Richards lab has projects that apply genomics and epigenomics approaches to help to understand plant invasions in Japanese knotweeds and Spartina alterniflora. I aim to learn their techniques and look to apply them to growth in microgravity.

Cassandra Campbell
Bio
I study how climate change drives shifts in vegetation in wetland communities, and investigate the resulting changes in plant-soil dynamics. My current dissertation research focuses on the recent expansion of mangroves into salt marsh territory on Florida's Gulf Coast. I am exploring the factors driving changes in the spatial arrangement of mangrove forests, and documenting changes in soil properties that occur as a result of mangrove encroachment. Because mangroves are expanding poleward following changes in climate and sea level, I hope that my work will be used to predict changes in wetland ecosystem dynamics on a global scale.

I am a first-year Ph.D. student working with Dr. Diego Santiago Alarcon. Birds are my big passion; anything related to them excites me. My main interest is looking at how different changes in the land and environment affect bird communities. I am curious about how they manage to live and even do well in these changing habitats.
During my master's at the Indian Institute of Science Education and Research Tirupati, I studied the impacts of exotic timber stands on the bird communities in the Western Ghats' Sky Islands. After that, I worked as a research assistant at the Salim Ali Center for Ornithology and Natural History on a project monitoring bird diversity and populations in the Andaman and Nicobar Islands.
Now, for my Ph.D. at USF, I will be digging into how urbanization impacts bird communities. When I am not busy with research, you can find me birdwatching or cooking. I love exploring new places, trying local food, and learning about different cultures. Whenever I visit somewhere new, I make it a point to bring back a unique recipe. I have also got a passion for singing and putting together events.
My life is a mix of uncovering bird secrets in my studies and enjoying the world beyond research through travel and my hobbies.

Dylan Gallinson
Bio
I joined the Margres lab in 2021 while enrolled in a master’s program to study Tasmanian devils and devil facial tumor disease (DFTD), a species-specific transmissible cancer. Transmitted via biting, devils are universally susceptible to DFTD which is always fatal, and devils are now threatened with extinction due to DFTD. For my thesis, I used a massive genomic sequencing dataset and computational tools to investigate devil-DFTD coevolution and found the first evidence in this system that devils and DFTD are likely coevolving.
I began my Ph.D. in the Margres lab in 2022 where I continue to study devils and DFTD using genomics and high-performance computing. However, I have shifted my research focus to studying the evolution of DFTD and am specifically interested in studying how the acquisition of transmissibility in DFTD impacts its evolutionary trajectory relative to typical cancers.

My research will investigate the impact of feral pigs on ecosystem properties, such as soil nutrients, vegetation growth, and species composition, in cypress wetland and pine upland habitats throughout Florida. With game cameras, I will observe feral pigs to better understand drivers in site selection for rooting and interactions that take place directly or indirectly with feral pigs and their rooted plots. Lastly, I hope to address the human-wildlife conflict associated with feral pigs by surveying people in agricultural residential areas, suburban communities, and natural environments to better understand how the public classifies and interacts with this species. Since feral pigs are extensively hunted in Florida, many individuals view them as a game species which promotes their presence in the environment and disguises the fact that they are invasive. Through my research, I hope to convince the public and policymakers that there must be better management and control of feral pig populations.

Upon capturing my first snake at the age of three, the love of reptiles captured me! I served more than 500 hours in animal husbandry and public education at the Florida Aquarium, produced over 60 videos on my YouTube channel, and assisted in gopher tortoise conservation projects under George Heinrich since 2018.

During that time, I served as president of the biology club for two years, bringing in notable speakers like Coyote Peterson and Dr. Whit Gibbons. I also worked on a literature review of anthropogenic impacts on snake species richness across the globe with additional primary research of its impacts within Florida. In my spare time, I delight in studying theology, camping, adventuring, traveling across the US, and my favorite herping.

Hi there, I'm Danny! I joined Dr. Scott's lab as an undergraduate researcher in 2023, and graduated with a B.S. in Biology from USF in 2024. I then rejoined Dr. Scott's lab as a master's student in 2025. My current project is based in microbial physiology and microbial ecology, and is focused on a novel species of bacteria that can be found in small sulfidic springs in the Tampa area. This organism is believed to belong to a small genus in the Piscirickettsiaceae family, with currently only one other species in it!
My other research interests include, medical microbiology, chemical biology, chemical ecology, and epidemiology!

Bio
My name is Jake and I study poison dart frog behavior in Dr. Yusan Yang’s lab. Specifically, I am focused on how ecological resource availability alters sexual selection, parental care behavior, and tadpole development. Additionally, I am interested in finding out what sexual traits, e.g. color, body size, courtship effort, are most important in mate choice and how they may vary in importance between species with different mating systems and parental care behaviors.
I received my B.S. in Biology from Saint Louis University in 2023, where I studied vibrational communication in invertebrates.
