Assistant Prof. PAMELA THOMSON MORALES. Veterinarian. Master in Biological Sciences, Mention Microbiology. Doctor in Biomedical Sciences.
Dr. Thomson graduated as a Veterinary Doctor in 2002 and began her specialization in Microbiology and Mycology by completing a Master’s degree at the University of Chile, then she moved to Spain to continue with a Doctorate in Biomedicine at the Rovira i Virgili University.
She extended her research activities by undertaking a post doctorate at the Catholic University of Chile, focusing her work on the human gut microbiome. She perfected this knowledge with an internship in Valencia at the Foundation for the Promotion of Health and Biomedical Research (FISABIO).
Since 2020, she joined the Universidad Andrés Bello, where she participates as a teacher in undergraduate courses such as Aggression and Organic Defense, Zoonosis and Title Seminar. She coordinates courses on Clinical Microbiology, Food Safety and One Health Impact in Veterinary Medicine. She participates as a postgraduate teacher, forming part of the academic body of the Conservation Medicine Doctorate.
Additionally, she founded and is the present director of the the Clinical Microbiology and Microbiome laboratory, located at the “Avda Lo Pinto, Chicureo Colina” headquarters, where teaching, research and microbiological diagnosis activities are carried out, working directly with the veterinary clinical hospital.
She is a member of the Microbiology Society of Chile, a member of the International Microbiota Society. She is editor of Frontiers Veterinary Science, in the Animal Nutrition and Metabolism section and Editor of Frontiers in Microbiology, in the Microorganisms in Vertebrate Digestive Systems section, among others.
She recently started to collaborate with the Sporotrichosis group of the Mycotic Diseases Branch Teams of the Centers for Disease Control and Prevention (CDC) USA.
