Title: Data Science Meets Human Neuroscience: How to Teach a Computer to Read Brain Waves
Abstract: Clinical human neuroscience research addresses some of the hardest scientific challenges of our day. Addressing these problems involves the ultimate of team science, integrating a diversity of fields from physics to physiology and from medicine to mathematics. We use the most advanced computational methods to analyze the most advanced compututation tool itself鈥攖he human brain. In this talk, I will discuss multiple career trajectories that can prepare students to engage in this research. I will also provide an overview of several of my exciting research projects, including live monitoring of depth of sleep from premature infants to older individuals with Parkinson's disease, and mapping of function and dysfunction in patients with epilepsy.

Title: Investigating the Ocean's Biological Carbon Pump Using Argo Profiling Floats
Abstract: Whale sharks have a reputation as enigmatic, peaceful giants leading a solitary existence in the vast expanses of the open ocean, but many of our assumptions about this species have been proven wrong by recent research on their population biology, demographics, and movement ecology. Rather than detracting from their appeal, our findings paint an even more vivid picture of a charismatic and long-lived species that still holds tightly to many of its most important secrets, particularly those relating to reproduction. They also underscore just how difficult and intractable this species is to study, perhaps more than any other marine megafauna species. Whether it is their tough, thick skin, their relative rarity and unpredictability, or their extraordinary deep diving behaviour, whale sharks make us work hard for every data point. Nonetheless, technology is increasingly helping us gain insights into the lives of these beautiful animals and their interactions with many others species with which they share their open ocean habitat. These insights are important as we come to realise that the species is growing increasingly endangered.
Informed conservation plans will need to be multilateral and coordinated across many developing economies in the tropics, and will require conservation NGO鈥檚, regional fisheries management organisations, tourism industry stakeholders and sovereign governments to work together. But perhaps the greatest hope for whale sharks will come from a marked increase in awareness of this species and a transformation in cultural values attached to its plight, fueled by their increasing prominence in pop culture and their featuring in a handful of public aquariums large enough to effectively display them. This is promising because analysis shows that the population has the capacity to rebound to pre-industrial levels if threats such as ship strike and plastic pollution can be effectively mitigated.

Title: To find our voice, you must listen to the voices of animals!! What is language & how did it evolve in the only extant bipedal naked ape? 鈥︹�nd what the heck does a rat have to do with it!!!!
Abstract: In this riveting SELS talk I will discuss the evolution of language, with an emphasis on Darwin鈥檚 insights and animal communication. Like many other topics, Darwin had something to say about language. His original ideas on language may not be far from reality. How did gestures or music potentially lead to a trait that distinguishes us from the rest of the animal world? And how might animal vocalizations help us to understand human language? Want to know more, well you鈥檒l just have to come and find out (and get cake to celebrate Chuckie D鈥檚 216th birthday!!!!!!)!
Bio: Dr. V enjoys watching birds, cuddling with her million cats and Hector (huge white fluffy over-protective dog you may have seen or heard in her office), eating ice cream and watching Star Trek.

Title: The Rarest of the Rare: Fire Ecology, Long-Term Demography, and Conservation of the Endangered Plants of the Lake Wales Ridge (Central Florida)
Abstract: Fire is a fundamental regenerative ecological process in ecosystems globally. In particular the pyrogenic Florida scrub habitat has evolved to rely on fire as a critical source of habitat renewal, and many species are reliant upon fire for successful recruitment and population persistence. However, fire application is not one-size fits all, with many species having diverse fire requirements and adaptations. Decades of demography conducted by Archbold Biological Station has illuminated the unique fire needs of the endemic plants of the Lake Wales Ridge. This fundamental work has further informed the best land management practices for conservation of these often extremely rare species, including prescribed burning and plant reintroductions. This talk highlights several of the 鈥渞arest of the rare鈥� species of the Lake Wales Ridge, such as Florida ziziphus (Pseudoziziphus celata) and Florida perforate reindeer lichen (Cladonia perforata), and their evolutionary journey toward becoming some of the most distinctive species in Florida.
Bio: Sterling Herron is a Plant Ecology Research Assistant V at Archbold Biological Station, specializing in the botany and conservation of endemic plants of the Lake Wales Ridge in south-central Florida. Sterling earned his B.S. in biology and chemistry from Milligan University (Milligan, TN) and his Ph.D. in biology from Saint Louis University (St. Louis, MO). His graduate work covered exploration of herbaceous perennial crop wild relatives and their potential as new grain crops, in collaboration with the Missouri Botanical Garden and the Land Institute. At Archbold, he has had the opportunity to work with over a dozen endemic and endangered plant species unique to the Lake Wales Ridge, leading long-term demographic studies on these species, as well as implementing reintroductions of endangered species. His philosophy is that it has never been more important to understand and preserve the endemic species of Florida, with the rising tide of the state鈥檚 population as well as impending threats from climate change.

Title: Cross-species Adaptation: Molecular Footholds and Viral Transcriptional Programs in Poxviruses
Abstract: Cross-species spillover events from animals to humans are responsible for many of
the major pandemics in human history, including Covid-19, avian influenza, and HIV.
Yet we still know relatively little about the evolutionary steps that allow a virus
to cross species barriers and establish efficient replication in a new host. In my
lab, we model this process using vaccinia virus and the antiviral protein PKR as a
central barrier to infection.
Using experimental evolution in weakly permissive African green monkey (AGM) cells,
we demonstrated that rapid gene amplification of a weak viral antagonist occurred
early and was sufficient to fully rescue virus replication. In otherwise completely
non-permissive human cells, this same amplification enabled the virus to evade multiple
barriers to replication and accumulate distinct, species-specific mutations, many
in subunits of the viral RNA polymerase. Taken together, these data suggest that gene
duplication can act as a 鈥渕olecular foothold鈥� for host jumps.
In the second part of the talk, I will present new time-resolved transcriptomic and
proteomic comparisons between vaccinia infections in AGM and human cells. We identified
differences in the timing and magnitude of viral gene expression, as well as host
proteins that are differentially regulated in AGM and human cells. Together, these
results suggest that cross-species adaptation reflects not only overcoming host restriction
factors like PKR, but also a central and previously unrecognized role for viral transcription
in adaptation to new species.
Bio: Greg Brennan is Associate Dean of Research and Basic Sciences at the new Lincoln Memorial University鈥揅ollege of Veterinary Medicine at Orange Park in Jacksonville, Florida. His work integrates immunology, infectious disease biology, and functional genomics and proteomics to investigate the role of host restriction factors and viral evolution in zoonotic emergence. Using experimental evolution, his laboratory has shown that gene amplification can act as a 鈥渕olecular foothold,鈥� enabling viruses to productively infect new hosts. Before joining LMU, he held research positions at institutions including the Fred Hutchinson Cancer Research Center and the University of California, Davis. As Associate Dean, Dr. Brennan leads the development of LMU-OPCVM鈥檚 research enterprise, including student research training, research infrastructure, and interdisciplinary One Health initiatives.

Title: Hunting Ghosts in Low-Earth Orbit
Abstract: The National Oceanic and Atmospheric Administration (NOAA), working in partnership with the National Aeronautics and Space Administration (NASA) and the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) is investigating the feasibility of implementing small satellite remote sensing in low-earth orbit (LEO). The small satellite remote sensing platform will use the Data Collection System (DCS) transponder onboard the NOAA Geostationary Operational Environmental Satellite (GOES) as a relay to earth. Two experimental LEO spacecraft have been flown so far. The initial tests, while promising have occasionally been impacted by spectral anomalies, known as ghosts, that appear to track alongside the desired signal in the three dimensional received-energy plots known as waterfall displays. The characteristics of the ghosts suggest they are generated by the small satellites but are being altered by the environment before being received by the GOES 16 spacecraft. The most likely explanation for the presence of the ghosts appears to be doppler-shifted, multipath reflections of the small satellite transmissions by the earth itself. This is believed to be the first small satellite LEO-to-GEO-to earth relay link to be studied and the ghost phenomenon remains an open research topic. More tests are planned with the GOES 18 and GOES 17 spacecraft as well as the new but similar EUMETSAT Meteosat 12 satellite. Another small satellite experimental platform is also planned for launch in the near future.

Title: Seaweed and the World鈥檚 Forgotten Forests
Abstract: Seaweeds, also known as macroalgae, form some of Earth鈥檚 most biodiverse and productive forests. This talk will share new insights about the role seaweed forests play in the marine environment, their global distribution, and their responses to and climate change. Drawing on my research, I will discuss how seaweeds are shifting their distributions, altering their growth rates, and adapting to rising ocean temperatures. I will highlight the ecological consequences of these changes for marine biodiversity and the communities that depend on seaweed forests. The talk will also present recent evidence that shows that seaweed forests play a more important role in the ocean carbon cycle than previously thought, and will examine potential ways to use seaweeds to provide climate benefits as 鈥渂lue carbon鈥�. It will end by discussing how research and industry are harnessing the potential of seaweeds by farming them to contribute to future food security, environmental sustainability, and climate change mitigation.
Bio: Dr. Pessarrodona is a Postdoctoral Research Fellow at the University of Western Australia. His research revolves about understanding how marine forest ecosystems work, and how stressors (principally climate change) alter their functioning. Recently he has become very interested in the role seaweeds play in the coastal carbon cycle at the global level, and whether seaweeds can provide solutions to climate change mitigation. He is a spade-and-bucket ecologist who tries to spend most days underwater making natural history observations and experimental manipulations. Dr. Pessarrodona often combine such evidence with experiments in the lab. He is however convinced that understanding of marine forests at scales relevant to human decision-making requires interdisciplinary partnerships. As such, he collaborates with molecular ecologists to complement the ecological and physiological insights gained through my research with genomic approaches.
Title: Non-Reproductive Vocalizations & Flocking Behaviors in Hybridizing Songbirds
Abstract: Avian song learning has been widely studied in songbirds, while the role of calls in speciation remains largely unknown. Avian calls, although primarily associated with non-reproductive behaviors, are learned and important for many aspects of survival, and are therefore important for fitness. Thus, like song, avian calls could influence reproductive isolation. My work is aimed at examining call learning and non-reproductive behaviors associated with the 鈥渃hick-a-dee鈥� call in hybridizing black-capped (Poecile atricapillus) and Carolina (Poecile carolinensis) chickadees. I examined how calls and call learning might affect pre- and postzygotic reproductive isolation. Parent species originating from sympatry show a stronger bias towards learning their conspecific call relative to their conspecifics in allopatry. In addition, hybrids showed reduced variability in call learning. This suggests calls could contribute to pre- and postzygotic reproductive isolation, potentially through mechanisms of ecological character displacement and hybrids exhibiting constraints on plasticity in call learning, respectively. I also examined whether mobbing behavior, an anti-predator behavior initiated by flocks using the 鈥渃hick-a-dee鈥� call, differs between natural sympatric and allopatric populations. I documented a lack of chickadee flocks in sympatry, relative to the black-capped and Carolina allopatric populations. Although the lack of chickadee flocks cannot be explained, I discuss potential impacts of hybridization on flocking behaviors from an ecological perspective. This work is some of the first evidence of call learning as well as different ways calls and call learning could indirectly affect reproductive isolation in a hybridizing songbird system. Overall, I present new avenues of research on understanding the effects of hybridization on non-reproductive behaviors from an ecological viewpoint, and further, the potential impacts on reproductive isolation.
Bio: Dr. Spinelli completed her Bachelor of Science with a minor in Visual Arts at Jacksonville University (JU) in 2018. She worked under Dr. Vanderhoff, performing a research study on the effects of urbanization on avian abundance and diversity, which is published in the Florida Field Naturalist. She then went to Lehigh University to pursue her Ph.D., which was recently completed in January 2025. She worked under the direction of Dr. Amber Rice, studying different potential reproductive isolating barriers between the naturally hybridizing black-capped and Carolina chickadees. Her dissertation work focused on non-reproductive vocalizations and behaviors in the two chickadee species and their hybrids, as these have been overlooked when considering mechanisms that can affect reproductive isolating barriers between species. For her dissertation work, she was awarded multiple fellowships and the Sigma Xi: Grants in Aid of Research. She also spent time volunteering at Lehigh for the Biological Organization of Graduate Students and the Graduate Student Senate to help advocate the graduate student鈥檚 needs to higher administration. She was awarded the Lehigh Graduate Life Leadership Award for the work she did improve conditions for graduate students. She is now exploring different potential career paths in conservation or environmental work.
