Dr. Maria Anita Mendes

She has a quite strong background in mass spectrometry (EI, CI, ESI, MALDI ionization methods and Quadrupole, TOF, TOF/TOF and IT-TOF mass analyzers). She has relevant work experience on HPLC, LC-MS and LC-MS/MS. In the last nine years she has been working as scientific researcher at the University of São Paulo (USP), responsible for the Dempster mass spectrometry laboratory. My main research projects are related to structural determination of unknown compounds present in environmental samples, samples of oil, and also the identification of microorganisms by MALDI new technique Biotyper. She has developed projects on Proteomics and Metabolomics field as well. (Lattes)

 

 

Dr. Meriellen Dias

Chemical Engineer from Aracruz College – ES (2010), Master in Physical and Chemical Sciences at Escola Politécnica – USP (2013) acting in degradation of pharmaceutical effluents by photo-oxidative processes. She has experience in High-Performance Liquid Chromatography, Semi-Preparative Chromatography. Currently she is a post-doctoral in the Engineering Department of the Polytechnic School in the project for the Recovery of Contaminated Areas and Mineral and Reject Extraction in partnership with VALE / BNDES with emphasis on Filamentous Fungus Proteomics by Mass Spectrometry (nanoLC-ESI-Q-TOF), Metabolome (GC-MS) and identification of microorganisms by MALDI-Biotyper.

Dr. Enrique Eduardo Rozas Sanches

Undergraduated degree in marine science from the Catholic University of the North, Chile (1995), Doctor in Science (Physiology) from São Paulo University and 3 times Post-Doctor from the same university (2010, 2012, 2015). Expert in Pharmacology, biochemical and microbiology, initially, searching for intracellular responses of neuroblastoma cells tumor induced by marine alga substances. After established the field search in pharmacological activities of marine microorganism sponge associated, he enlarged his focus, searching for bacteria associated to continental Amazonic sponge. These work searched for immunosuppressive compounds and its application in interface biotechnology. In this way, electronic waste bioleaching process using bacteria sponge associated was development to transform the leached copper to copper nanoparticles. Actually, has started to search the proteic continuous motors concept to H₂ accumulation as biogenic energy. (Lattes)

Dr. Monira Samaan Kallás

Bachelor’s degree in Odontology from UNIP (1997), specialization (2004), Master’s degree (2009) in Social Odontology from FOUSP and Habilitation in Hospital Odontology from the Federal Council of Odontology (2016). She has been a dentist of “Grupo Mais” since 2008, where she works with assistance and research in oral care in long-stay and palliative patients. PhD in the Health Sciences program of the Research Institute of the Sírio Libanês Hospital since 2014, where she developed research lines for oral health in the ICU:

Research Project 1: Evaluation of oral changes and oral flora modification in patients admitted to the Intensive Care Unit of the Hospital Sírio Libanês (microbiological evaluation of saliva and dental / prosthetic biofilm of patients on days 1, 4 and 8 of hospitalization through MALDI and metabolome).

Research Project 2: Alteration of oral flora in a hospice before and after the institution of an oral decontamination protocol. (Microbiological evaluation of saliva and biofilm before and after the institution of an oral hygiene protocol, through MALDI and metabolome). (Lattes)
