We are Dr. Sarah Zohdy’s Disease Ecology Lab!

Principle Investigator

Sarah_ZohdyDr. Sarah Zohdy,  is an Associate Professor of Disease Ecology in the School of Forestry and Wildlife Sciences and College of Veterinary Medicine at Auburn University.

Field Manager
Bernadette Rabaoarivola (Menja ) is our lead medical entomologist in Madagascar. She has worked as a field technician for Centre Val Bio in Ranomafana, Madagascar since 1999 on a wide range of projects. Menja is the heart of our mosquito research, and the local expert in Ranomafana. She began working with us in 2013, and has been managing our field teams and activities since 2015. Menja also plays a very important role in education and outreach, teaching people about the importance of mosquito vector control in and around Malagasy communities. She also trains children in basic biology and what mosquitoes can teach us about the natural world.

Postdoctoral Scholars
Dr. Maria Andrea Camarano Eula is currently a postdoc fellow. Andrea graduated from the National University of Uruguay with a degree in Pharmaceutical Chemistry. She worked for almost 14 years as an analytical chemist in quality control of drugs and medicinal products for human use in the official laboratory of quality control of drugs in Uruguay (Commission for Drug Quality Control), which is also one of WHO’s reference laboratories in South America. She also gained experience in Regulatory Affairs working in the Medicine Department of the Ministry of Public Health of Uruguay. In February 2014 she moved to São Paulo, Brazil, and enrolled in the Postgraduate Program of Toxinology at Butantan Institute pursuing postgraduate studies and aiming for further personal and professional growth. In her Ph.D. project, she studied the molecular mechanisms underlying Micrurus corallinus envenomation, using mainly a transcriptomic approach. She earned her Ph.D. in Science – Toxicology in august 2018. Since Andrea has always been concerned about human public health topics, she is now involved in a project aiming the development of new platforms for infectious disease diagnostics.

 Graduate Students
Kayleigh Chalkowski is a PhD student.  After earning her B.Sc. in Biology from Cornell University, Kayleigh has spent the last four years doing on-the ground conservation work on Kaua’i. Her field experience with the diverse set of avifauna in the Hawaiian islands gave her an appreciation for effective predator control and an interest in diseases that impact endangered species as well as humans. Following this passion, in Fall 2017 she started her PhD in the Cell & Molecular Biosciences program studying population genetics and virulence of Toxoplasma gondii strains in Hawaii. In addition to her research at Auburn, she is a freelance artist and is the co-founder and curator of The Endangered Ark– an annual art exhibit in Honolulu, HI that calls attention to issues surrounding endangered species through art and community action.

Katie Izenour is a PhD student. After earning her MPH in Epidemiology from Tulane University, she has spent almost 10 years working as a consultant for the government supporting the US Navy, US Air Force and Centers for Disease control and Prevention. Most recently she was an analyst at the President’s Emergency Plan for AIDS Relief (PEPFAR) in Washington DC conducing analysis of on routinely collected data for Male Circumcision as well as for adolescent girls and young women. Katie’s passion has always been animals; feeing unsatisfied with her desk job, she took a leave of absence in 2016 to spend a total of three months volunteering at an animal shelter in Cairo, Egypt and at a wildlife sanctuary in Agra, India. It was during this trip that she decided it was time for a career change and time to get out from behind her desk and time to finally do something that she was excited about. Given Katie’s broad background in public health and data analysis she started her PhD in the Department of Pathobiology at Auburn University’s college of Veterinary Medicine the summer of 2018.  Katie’s PhD research explores the relationship and interface between domestic animals, their vectors, humans and the pathogens that can move between them in Cairo, Egypt. Her decision conduct her research in Egypt arose from realizing how litter information there was about animal health, vectors and vector borne diseases in Egypt and North Africa. The opportunity to contribute to the body of scientific work has been Katie’s passion.

Katie was the recipient of a Fulbright Fellowship to Egypt, 2019-2020 during which time she lived in Cairo, Egypt, to collect her samples, learn Arabic and experience all that Egypt has to offer. She collaborated with Dr. Fayez Salib at Cairo University’s Faculty of Veterinary Medicine, Department of Infectious Diseases to collect samples and process them in the University’s laboratory. She has incorporated some innovative technology to her research – The Bento Lab portable laboratory and Cellabs Tropbio Filter Paper Blood Collection DisksTM.

Jocelyn Lindner is a graduate student working towards an M.S. in Zoology from the University of Otago, New Zealand. She completed her undergraduate studies at the University of Hawaii at Manoa where she graduated in Natural Resource and Environmental Management, specializing in Wildlife Management. Part way through, she studied Rainforest Management abroad with the School for Field Studies to the North Island of New Zealand and Queensland, Australia. She was also an intern for the Hawaiian Institute for Marine Biology shark lab, the Marine Mammal Research Program and a volunteer at the Honolulu Zoo elephant section. She then returned to New Zealand and graduated with a Postgraduate Diploma in Wildlife Management from the University of Otago. Now, she is a member of the Evolutionary and Ecological Parasitology research group with supervision from Professor Robert Poulin. Her thesis aims to determine the diversity and abundance of parasites in Eulemur macaco, the black lemur. This entails collecting fecal samples from three locations in Madagascar, and using microscopy and sequencing to compare parasites between individuals, groups, and environments. “I am very fortunate to have Sarah Zohdy as my co-supervisor and to be included as a member of the Disease Ecology and Evolution in the Tropics lab.”


Undergraduate Students
Haley Stephens is a junior studying microbiology. After being diagnosed with type 1 diabetes a couple months before starting college, she realized just how much we have yet to discover in terms of disease diagnostics and treatment. Her interests are in both autoimmune and infectious disease research, and she plans to pursue a Master’s degree in either field upon graduating. Currently, Haley is an undergraduate researcher working in the fields of  both analytical chemistry and infectious disease diagnostics developing microfluidic devices for pathogen detection.
