I am interested in a wide range of topics dealing with the ecology and evolution of marine organisms including charismatic invertebrates like corals and molluscs, as well as other less known but equally fun critters like algae, fungi and microbes. My google scholar profile is available here.

I research host-microbe interactions in corals and the jellyfish Cassiopea xamachana, using next-generation sequencing and microscopy as well as experimental ecology studies to address a wide range of questions.
Sofia Roitman, sxr410 at psu dot edu
I am interested in coral microbiology, microbial ecology, and host-microbe interactions. I am currently pursuing research projects that focus on the coral microbiome and how microbial diversity and community structure affect coral health and vulnerability to disease.
Julia Stewart, jus1828 at psu dot edu
I am interested in the mechanisms of symbiosis in the innate immune system of Scleractinians, as well as the gene flow and uniqueness of Orbicella faveolata, and other corals.
Ana María González Angel, amg449 at psu dot edu
I am interested in coral reproduction, ecology and evolution; and I have focused on reproduction in the Orbicella species complex. I am studying the reproductive isolation mechanisms that prevent these organisms from interbreeding including pre-zygotic temporal isolation and pre-zygotic gamete recognition.
Viridiana Avila Magaña, vxa146 at psu dot edu
My research is focused on comparative marine genomics of cnidarian-algae symbiosis. I am interested in combining bioinformatics and field research; in particular, the molecular recognition and cell-cell communication during the establishment of symbiosis between cnidarians (Corals and Jellyfish) and Symbiodinium. Thus, understanding how these mechanisms evolved in different species. Ultimately, I aim to describe coral bleaching in terms of the disruption of communication that takes place between the different members in the holobiont.

I’m interested in exploring the genetic connection involved in the symbiosis and regeneration seen in Cassiopea sp.

I am majoring in Biology with minors in Marine Science, and Wildlife and Fisheries. I am currently studying the process of host-symbiont specificity between multiple Symbiodinium species and Cassiopea xamachana. Like other Cnidarian organisms, each species usually has one specific symbiont that inhabits its tissues in a natural environment; however, there are many different species of Symbiodinium present in the environment. I am currently proceeding with competitive experiments between different Symbiodinium species in varying conditions to help determine what causes successful and unsuccessful infections from symbiont to host.

I am a freshman majoring in Biology, focusing on the Vertebrate Physiology track with a minor in Marine Science. I was excited to be able to join this lab because of my interests in marine biology and coral microbiology. My career goals include either attending graduate school to focus on marine biology or attending veterinarian school with hopes of becoming an aquatic veterinarian one day. Currently, I am being trained to perform PCR analysis and Electrophoresis Gel runs as well. I am helping to assist on the Global Coral Microbiome Project, under the supervision of Sofia Roitman. I look forward to learning new information and acquiring new research techniques as I grow throughout the years in this lab.

I am a sophomore majoring in Biology with the Vertebrate Physiology option and a business minor. I am interested in exploring coral symbiosis with bacteria and other marine life. As an undergraduate student in the Medina lab, I am currently working with multiple Symbiodinium species to develop growth curves for them. My work is under the supervision of Allison Kerwin, our postdoctoral fellow, and Victoria Sharp, a Ph.D. student. I hope to be an integral part of the research team throughout my remaining time at Penn State, and further my knowledge of the ecology of coral and the fundamentals of research techniques
Leslie Johnson, lwj5052 at psu dot edu
I am a senior majoring in Biology with a concentration in Genetics and Development. I am currently working with Allison and Dr. Medina to characterize the physiology of symbiotic bacterial strains associated with Orbicella faveolata. Current knowledge of coral bacterial physiology is largely limited to only knowing the metagenomic potential of each particular strain; by determining what nutrients and compounds each strain can and cannot metabolize and comparing our results with already obtained sequences from each strain, we will be able to determine gene expression in these strains under laboratory conditions. I am interested in a variety of topics including coral conservation, population genetics, the rise of new species in groups such as cichlid fishes as a result of adaptive radiation, and the effect of vicariance on species history. I am passionate about science education and outreach, and hope to teach courses in genetics and evolutionary biology at the college level after earning my Ph.D. I am also a Learning Assistant in Dr. Medina’s Fall 2018 Evolutionary Biology course, and love helping my fellow students learn!
