David Ribeiro (DR) graduated in Chemistry at the Faculty of Sciences of Porto University in 2004, concluded a master´s degree in Quality Control - Water and Food, at the Faculty of Pharmacy of Porto University in 2007 and earned a PhD in Pharmaceutical Sciences - Analytical Chemistry at Faculty of Pharmacy of Porto University in 2012, financed by FCT grant SFRH/BD/42571/2007. In 2013, DR was hired as an assistant researcher by LAQV/REQUIMTE, at Porto University, under the framework of QREN through the project NORTE-07-0124-FEDER-000067, where he initiated his current research line in the fields of Analytical Chemistry and Nanotechnology. From 2015 to 2019, he conducted his research as a postdoctoral fellow (financed by FCT grant SFRH/BPD/104638/2014) at the same host institution. Since March 2019, he has been continuing his research work as a researcher hired by LAQV REQUIMTE at FFUP through program DL 57/2016 - Norma transitória. His research activity has been focused on the synthesis and characterization of semiconductors QDs with binary and ternary arrangements (CdTe and AgInS2 QDs) and carbon dots (CDs) for use as valuable tools in the development of chemiluminescence and photoluminescence-based methodologies for monitoring a myriad of analytes with environmental, pharmaceutical and food interest. His scientific research has resulted in 57 papers in international peer-reviewed journals, 2 in national journals and 2 book chapters. Additionally, all his research has allowed participation in both national and international conferences with the contribution of 33 oral presentations and 55 poster communications. He also participated in the organization of 2 national conferences. He was an integrated member of several financed projects, among which his participation in the projects "Nanoquímica" and " FOODSENS - Transferência de Tecnologias para reduzir riscos alimentares", as a researcher is noteworthy. DR was responsible for the co-supervision of 7 MSc students of Pharmaceutical Sciences and Bioengineering on their scientific initiation (course of Project I) and for tutoring 6 PhD and 2 MSc foreign students on a mobility program. He is currently co-supervising a doctoral fellow with reference 2020.08465.BD. Since 2014, he has collaborated in the laboratory classes of the MSc in Quality Control and in Analytical, Clinical and Forensic Toxicology. He is also teaching laboratory classes of General and Inorganic Chemistry and Analytical Chemistry in the integrated master's degree in Pharmaceutical Sciences, under the collaboration agreement between FFUP and REQUIMTE. Since 2020, he has also been collaborating in theoretical classes of Nanotherapeutics and Nanodiagnosis of the Integrated MSc in Bioengineering, a branch of Molecular Biotechnology.
