Cassandra Campbell |
Program: Ph.D. Research 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.

Harikrishnan Cherayipadinjakkara
|
Program: Ph.D. Research Bio 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.

Kamarri Davis
|
Program: M.S. Research Bio My name is Kamarri Davis, and I will be starting my first semester as a master’s student
working in Dr. Deby Cassill’s lab. I am passionate about tracking changes over time
as they relate to both the biodiversity and ecology of ecosystems. My research will
focus on understanding the current and past behaviors and preferences exhibited by
Florida Scrub Jays in relation to changes in both the range and makeup of Florida
scrub habitat over the last 50 years, with the help of collaborators at the Archbold
Research Station.
I attended USF Tampa for my undergraduate studies, majoring in biology with a concentration
in ecology and evolution and minoring in environmental science and policy. I had the
privilege of interning with the National Audubon Society, where a large portion of
my work centered around organizing outreach events and lobbying for local environmental
policy reform. Additionally, we sought to oppose new policies that, although not yet
signed into law, would have negatively impacted the environment in ways we and the
public did not favor.
Currently, I am an intern with the USDA, where my work focuses on locating, rearing,
and releasing biocontrol agents on invasive plants throughout Florida, both aquatic
and terrestrial. We aim to track the long-term impact our biocontrol agents have on
reducing the vigor and rate of proliferation of such plants, considering our government's
three-pronged approach to addressing the matter: chemical, mechanical, and biological
means of control. In addition to this work, we have conducted resource competition
studies and predator-prey interaction studies. We have also assessed how physiological
changes within a targeted plant, after the initial release of our biocontrol agent,
impact the long-term success and preference of our biocontrol agent if a repeat release
were to occur.
With that said, I hope to apply all the skills I have acquired through past experiences
during my time in the conservation biology program once I matriculate this fall. Together
with Dr. Cassill, we will determine how human activities have impacted Florida's only
endemic bird.

Frank DeJohn
|
Program: M.S. Research Bio My name is Frank DeJohn, and I have worked as a Biological Scientist at the Fish and
Wildlife Research Institute (FWRI) for the last 2 years analyzing data and managing
the day-to-day operations of the State Reef Fish Survey, which aims to collect data
to improve the precision and timeliness of catch and effort estimates for various
reef fish species in the State of Florida.
Currently, I am pursuing a Master's degree in Conservation Biology under the mentorship
of Dr. Deby Cassill. My research focuses on the spatiotemporal patterns of nest site
selection in leatherback sea turtles (Dermochelys coriacea) along southeastern Florida beaches. This study is a collaborative project between
the Loggerhead Marinelife Center and our Conservation Biology M.S. program. In response
to increasing anthropogenic challenges, including rapid climate change, my research
aims to improve management and conservation efforts for these critically endangered
sea turtles. By understanding the nesting behaviors and preferences of leatherback
females in this region, we strive to contribute valuable insights for the protection
and preservation of their populations.
My passion for sea turtle conservation ignited during an internship with FWRI, where
I prepared biological samples (skin, blood, shell scutes, and non-viable unhatched
eggs) for stable isotope analysis. This experience inspired me to study animal behaviors
and their interactions within ecosystems.

|
Program: Ph.D. Research Bio I joined the Parkinson lab in 2022 to investigate how intraspecific variation among
endosymbionts effects host tolerance.
I developed a fascination with corals and their endosymbionts while completing a Research Experience for Undergraduates in Little Cayman Island while attending Southern Utah University. After acquiring my undergraduate degree, I moved to the Florida Keys, where he worked
to restore degraded reefs with the Coral Restoration Foundation. At USF, I plan to study how intraspecific variation within endosymbionts influences host resilience. |

Christina Iovino
|
Program: Ph.D. Research Bio 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.

quantitative methods in wildlife ecology and epidemiology of wildlife diseases. I
aim to develop computational tools that capture the complexities of disease spread
and contribute to the advancement of disease ecology research. With Dr. Kramer, I
will be predicting the future of SARS-Covid19 in ecological communities.
Beyond my research ambitions, I am deeply committed to raising wildlife conservation
and education programs in the area's proximity to wildlife habitat.
In my free time, I love to travel, especially to natural areas where I can trek and
hike in Mountainous regions. There's something always exciting about sinking in nature's
beauty, away from the bustle of everyday life. I also enjoy watching soccer and cricket,
and on occasion, I don’t mind joining a game for some friendly competition.

Riley Phillips
|
Program: M.S. Research Bio I graduated with my B.S. degree in Biology from the University of South Florida (2024)
where I did research on organisms conducting the reductive critic acid cycle pathway,
and separately on the behavior of a captive North American river otter at an AZA-accredited
institution. I have continued my education at USF by pursuing my masters degree in
Ecology and Evolution.
I am currently exploring what research and systems I will be doing with Dr. Lajeunesse;
however, the main topics I am looking at are parasites manipulating host behavior
and herbivorous insects exhibiting cannibalism. The goal is to place the herbivorous
insects in various environmental conditions to study the frequency of cannibalism,
with parasitized prey being one of them. I strive to answer the 'why' questions about
cannibalism in the science world as it is such an interesting and unique behavioral
trait.

attending the North American Diatom Symposium in October 2024 where I will be giving
a presentation on regional morphological variation of diatom species.
My future research will continue to focus on diatom taxonomy and ecology in the state
of Florida in an effort to better understand indicator species and to help monitor
the long-term health of impaired or at-risk water systems so that realistic restoration
and conservation goals can be defined.

Alex Seigel |
Program: M.S. Research Bio I am currently looking at the use of environmental DNA in pre- and post-restoration
sites (Robinson Preserve and Alligator Creek) to measure the biodiversity of the water
system compared to traditional seine netting.
We are also looking to see if any unknown/elusive native (sharks, rays, etc.) or invasive (walking catfish, aquaria species, lionfish, etc.) species have been utilizing these habitats as those need to be factored into measuring the overall success of the restoration itself. I am hoping to better understand the pros and cons of utilizing eDNA alongside seine nets when measuring biodiversity of tidally influenced water systems. |

Jana Wieschollek |
Program: Ph.D. Research Bio Hey, I am Jana and I am a graduate student from Germany! I am a Ph.D. student at Dr. Scott’s lab. My earlier research includes work on the biochemistry of army ants and their parasites as an undergraduate student and a Master Thesis focused on mitigation of the Florida Red Tide organism Karenia Brevis via algicidal bacteria. My Ph.D. project is going to focus on genetically interesting bacteria. These bacteria produce Carboxysome microcompartments, which help the organism with CO2-fixation. Interestingly, the bacteria seem to miss genetic information for important enzymes that are necessary for CO2-fixation. I hope to solve some puzzle pieces in this paradox for a better understanding of those organisms. A better understanding could lead to multiple applications, such as bioengineered CO2 fixation (not part of Scott’s lab research). |
