#help me correct Because of my previous experience in food industry and regulatory affairs, in 2000, I was invited by Dr. Prijs to join the microbiology courses. I teach lectures in microbiology and food safety, and I'm responsible for the laboratory of food microbiology. During my time here, the update of diagnostic methodologies for food-associated pathogens, under the CLSC and ISO standards have been achieved. Also, the study of regulatory issues associated with the food industry have been included as a regular part of the courses. I have also participated in Biotechnology and industrial microbiology courses where we encourage the students to investigate about the variables of the food production process, as well as the development of new products, especially those that are obtained through the microbial metabolism. I oversee the students professional internships in companies and laboratories related with the food industry.

#Help me correct Later, I worked at SENA, a technology center that offers training in various areas of industrial impact. I was in charge of providing advice and training to local companies associated with the food industry, on hygiene and food handling issues, good manufacturing practices, HACCP and ISO2000. These industries include poultry companies, centers of cold storage, slaughterhouses, and restaurants.

#help me correct After completing my master's studies in 2008, I was invited to participate in the General Parasitology, Clinical Parasitology and Clinical Correlation courses at UDES. During these courses, I participated in a social integration project, where the prevalence of sexually transmitted diseases in high school students was evaluated. During this year, I also got a contract to manage the quality and regulatory affairs in Technological Business Centre. These units included the production of surgical clothing and sutures, pharmaceutical mixtures, a Tissue Bank, and a surgical material sterilization central. During my time in this company, we achieved the approval of the production and commercialization of various medical devices by regulatory authorities.

# help to correct In 2013, I started my master's studies and joined the Micro Research Laboratory attached to the Molecular Immunology Research Group, in the Faculty of Health. There, I studied the biological activity of natural and synthetic substances against Mycobacterium tuberculosis. My work in the laboratory, allowed to establish the potential of essential oils and vegetable extracts derived from endemic plants found in my region, and that are considered as weeds, in the search for new active principles for the fight against tuberculosis. Additionally, I had the opportunity to participate in a project focused on the evaluation of the bioactivity of silver nanoparticles adhered to plant fibers for the control of bacteria that cause food spoilage and foodborne infections. This research broadened the scientific perspectives on the application of nanotechnology to packaging systems made with natural fibers, which are widely used in the agricultural sector.

# help me correct: Later, in 2019 I worked in other company, where I developed similar functions, and was in charge of the processing of immunological samples for the monitoring of post-vaccination antibody development in both Broiler Chickens and Grandmother Chickens. Here, I also had the opportunity to participate in the health control programs on farms, through the establishment of sampling programs to monitor the health of birds and I was in charge of training the workers in biosafety matters. Additionally, I contributed with the development of the necropsy processing protocol to ensure the quality of the samples that were going to be processed in the microbiology laboratory.

I started my experience in the food area in 2006, in a company dedicated to the exploitation of the poultry industry and the livestock sector of all branches, such as incubation, breeding, fattening, sales, purchases, and export of poultry and livestock products, where I joined the Animal Health department. My work was focused on QC in the hatchery, a very important aspect of the health of the birds destined to produce fertile eggs, commercial eggs and broilers. I was in charge of the development of the quality control program based on the monitoring of microbiological and chemical parameters for the fulfillment of requirements and the assurance of the health conditions of the plant (Environmental, potable water, cleaning and disinfection and quality conditions of the day-old chick). I was also responsible for the processing of finished product samples, and raw materials for other business centers of the same company, such as the production of poultry feed, and products for human consumption such as fresh meat, sausages, and eggs.
