EducationPh.D. in Parasitology, Sao Paulo State, BRAZIL

I obtained my bachelor's in Biological Sciences from Pontifícia Universidade Católica de Campinas, Brazil (2004), and my MS and PhD in Parasitology from the State University of Campinas UNICAMP, Brazil (2012). My graduate projects both focused on fish parasites, specifically myxozoans and monogeneans. During my PhD I spent 9 months at the Natural History Museum of London, supervised by Dr. Timothy Littlewood, working on parasite mitochondrial genomes. I had a post-doctoral fellowship at the State University of São Paulo, Brazil (2013-2017), and researched taxonomy and molecular phylogeny of parasites from fishes, amphibians and reptiles from several regions in Brazil. Currently, I am undertaking a post-doctorate at Federal University of Sao Paulo (2018–), where I am continuing to explore the taxonomy and phylogenetic relationships of myxozoan parasites from freshwater stingrays and other fishes from the Amazon. In 2022 I am a visiting scholar at OSU, in the Bartholomew Lab, working with Dr. Stephen Atkinson to investigate transcriptomes of myxozoans from the Amazon, searching for the motility and biomineralization genes that underpin some of the unique adaptations of these parasites.

Education: Ph.D. in Biology, University Montpellier II France

 I am an associate professor at the department of Zoology of Tel-Aviv University (Israel). My research interests concern various aspects of molecular evolution with a focus on phylogenomics (reconstructing evolutionary relationships among species) and genome evolution (understanding genome evolutionary dynamics). My work concerns distant animal groups such as rodents, sponges, myxozoans, or tunicates and I am using high throughput sequencing approaches together with bioinformatics tools in order to reconstruct animal evolution. In collaboration with Dr. Jerri Bartholomew, we are studying the evolution of mitochondrial genome organization in Myxozoa.

I am interested in the interaction between marine photoheterotroph and dissolved organic matter, especially phosphorus and arsenic. Phosphate is a limiting factor most of the marine microbes in the surface ocean, while organic phosphorus becomes an important inventory that microbes can utilize. Arsenic, due to its similarity in chemistry, can be analyzed as an analog to phosphorus. Photoheterotroph like SAR11 clade is widespread throughout the ocean, even in oligotrophic waters. My research is focused on how the photoheterotroph take up phosphorus from seawater into their cells.

I am working at the Department of Aquatic Medicine of Jeju National University in South Korea. I am interested in the development of a rapid and precise diagnosis for fish pathogens, which will make it possible to get precise information on them. Such information apparently contributes not only to minimize the abuse of antibiotics and produce safe foodstuffs to eat, but also to minimize the emergence of multi-drug resistant bacteria due to such abuses. The techniques developed will be applicable to aquatic pathogens for humans as well as those for fish by using them to the hygienic grading system or HACCP program. Also, by using this method we are able to monitor the temporal and spatial occurrence of various fish pathogens in more rapid and easy ways.

Postdoctoral researcher, Department of Microbiology, Oregon State University; Ph.D. Zoology, Sichuan University, Chengdu, China

I graduated from Sichuan University with a doctor degree in Zoology. When I was a Ph.D student, I conducted studies on genetic diversity, evolution history and relationships of the four subspecies of Chinese Sika deer. The phylogenetic relationships among the families Cervidae, Moschidae and Bovidae were also investigated. After becoming a faculty member of Chongqing University, my interest focused on the mechanism of speciation and differentiation of Myxozoa. During my stay in the lab of  Dr. Jerri Bartholomew, we will be working on molecular evolution between parasites and their hosts as well as conducting field work.

I am employed by AQUOS, Aquatic Organisms Health Laboratory at the Federal University of Santa Catarina, SC, Brazil.  I work on parasite identification especially monogeneans and trichodinids and also other endohelminthic and ectoparasitic fauna.  Other research involves vaccine development and isolation of probiotics (lactic acid bacteria) from the intestines of silver catfish (Rhamdia quelen) tilapia (Oreochromis niloticus), surubim hybrid (Pseudoplatystoma) and pirarucu (Arapaima gigas).  We also work on parasitic fauna from farmed ornamental fish and those for human consumption.  We study the efficacy of the use of essential oils to treat fish parasites such as pepper rosemary, peppermint, basil, and ginger.  During my stay in the lab of Dr. Michael Kent, we have been working on Pseudocarillaria tomentosa egg treatment by heating and chlorine.  Results showed that the heat inhibited the larval development as well as did the use of chlorine which killed the parasites and inhibited egg development.
