Post-doctoral Fellowships in Geosciences

The Institute of Geosciences of the University of São Paulo is offering three post-doctoral fellowship positions, funded by the São Paulo Research Foundation — FAPESP and linked to the Thematic Project, entitled “The Rio de la Plata Cráton and the Western Gondwana Assembly” (FAPESP grant number 2015/03737-0). Professor Miguel Ângelo Stipp Basei is the project coordinator.

The Project aims at unravel the geochronologic and tectonic evolution of the Rio de la Plata Craton and its marginal belts in the context of Western Gondwana Assembly. The project started in 2017 with two major scientific goals: 1) the upgrade of isotopic and geochronological techniques at the Geochronological Research Center of the IGc-USP, applied to the geologic and tectonic aspects of the project; 2) the multidisciplinary studies on key lithostratigraphic units and tectonic features in the Rio de la Plata Craton and the African counterpart. 

The candidate should be mostly involved in the development of one of the research Projects (as described below), as well as on scientific dissemination and the teaching of tectonics and/or geochronology for graduate students. The selected fellows are expected to be able to conduct an empiric research including design data collection strategies, as well as to delineate research questions in close association with the development of Thematic Project, with publication of the results in national and international journals in the area of Geosciences.

• Postdoctoral 1: “Kinematics and age of the Major Shear Zones of the southeastern portion of Brazil and Uruguay. Comparison with equivalents lineaments of southwestern Africa”

The person involved will work directly in the kynematic characterization and tectonic modeling of large Shear Zones that compartmentalize the Pre-Cambrian domains of the Brazilian and Uruguaian eastern portion (Mantiqueira province) and the equivalent South African lineaments. The subproject in which the student will be linked is related to the development of the eastern border of the Rio de la Plata Craton (subproject 3.1.5). Structural, kinematic and thermo-chronological studies of the major lineaments occurring in the Ribeira and Dom Feliciano belts will be the major target of this project.

• Postdoctoral 2: “Upgrade of U-Pb and Hf methodologies on LAICPMS laboratory – establishment of new in situ analyses”

The fellowship will work directly on the improvement of the U-Pb and Hf methods in zircon, monazite and titanite to upgrade these systematics in the LA-ICP-MS laboratory, among other isotopic techniques. Post-doctoral student to address this issue should have extensive experience in handling LAICPMS to be able to meet the expectations that this activity requires.
Supervisor: Prof. Dr. Wilson Teixeira

• Postdoctoral 3: “Provenance studies of the sedimentary cover of the Rio de la Plata and Paranapanema cratons through the U-Pb analysis of detrital zircon of the Paraná Basin units”

The zircon provenance study of the sedimentary units that cover the Rio de la Plata and Paranapanema cratons, represented by the Paraná Basin units, will be the central theme of the third Postdoctoral project foreseen in this ThematicPproject. For this, detrital zircons of surface and sub-surface samples (the latter to be obtained from Petrobras drill holes) will be analyzed. In addition to sample collection, the predicted analyses involving pontual geochronological U-Pb determinations and Hf studies in zircon in the same crystals will be complemented by paleocrorrent studies and characterization of heavy minerals assemblages.

Post-doctoral Fellowship in Parasitology

The opportunity is for the project belonging to the Institutional Research Development Plan (PDIP), whose objective will be the development of scientific and technological solutions that will provide rapid and timely responses to strengthen laboratory actions in health surveillance. Project title: “Pre-clinical study of new candidate drugs against leishmaniasis”, coordinated by Dr. Andre Gustavo Tempone.

The present proposal aims to identify an approved drug by means of the drug repositioning or synthetic active compound based in a natural prototype, which presents promising anti-Leishmania infantum activity. The investigator will initially perform in vitro phenotypic assays using the intracellular amastigote model of Leishmania infantum to determine the activity of the compounds to be tested. Studies will be carried out in different cell lines to evaluate the mammalian cytotoxicity. Cellular studies, based on flow cytometry techniques, spectrofluorimetry and transmission electron microscopy will be used to investigate the possible mechanisms of action of the most promising compounds. Finally, in vitro pharmacokinetic studies (ADME) such as solubility, membrane permeability and metabolization will be performed as initial parameters for the design of animal model efficacy studies.

Pre-requisites for the position: Doctoral degree in area related to the project based on Drug Discovery in visceral leishmaniasis or Chagas disease; project experience involving techniques of phenotypic assays (intracellular amastigotes and cytotoxicity), experience in studies of cellular action mechanism; experience in pharmacokinetic profile studies and in vivo efficacy studies.

Post-doctoral Fellowship in Molecular Biology

The research group Bioproducts’ Production and Purification Lab (BioPPuL), located in the Department of Bioprocesses and Biotechnology of the FCFAr of UNESP, offers a postdoctoral fellowship to develop the recombinant microorganism for the production of L-asparaginase (ASNase) and studies of its production process by submerged cultivation.

About the project

Getting older is the biggest risk factor for most fatal diseases, including cancer, heart disease and Alzheimer’s. The advances in nanomedicine comprise the development of nanoparticles either for drug delivering or as platforms for biomolecules purification. Simultaneously, continuous progresses have been made for the development of recombinant therapeutic enzymes, namely L-asparaginase (LA), which presents antineoplastic properties for thetreatment of leukaemia’s, in particular for Acute Lymphoblastic Leukemia (ALL). Currently, the LA available in medical applications is produced from bacteria. However, this type of LA may activate the immunological system causing human hypersensitivity reactions. Therefore, the search for novel microorganisms able to produce LA with no side effects has been the main focus of many researches.

Considering the great demand for the development of new technologies for the purification of therapeutic enzymes, still limited by their high cost, this project aims to produce recombinant LA by bacteria fermentation and to developa cost-effective and sustainable platform for the biopharmaceutical purification (downstream processing) from the fermentation broth using nanomaterials. The main goal is to obtain recoveries of LA above 90% and purity levels over 95%, with a cost reduction around 20%. A critical evaluation of the best strategies and conditions for the integrationprocesses and scale-up will be explored.

The involved research teams (CICECO, FEUP and UNESP) have shown to be successful in providing pioneering scientific results on the production of enzymes and on the development of separation and purification techniques for biopharmaceuticals. The UNESP team from Brazil will optimise noveltechniques of heterologous enzyme production by bacterial fermentation, which is generally regarded as safe (GRAS) and easy to manipulate, in order to achieve higher enzyme yields. The Portuguese teams (CICECO and FEUP) will be responsible for the preparation of functionalisation of silica and carbon nanomaterials, which will be used as an efficient and fast strategy for LA purification from the fermentation medium. NanoPurAsp aims to meet the approval of biopharmaceuticals by regulatory authorities which require effective and high quality biopharmaceuticals, i.e., no side-effects, high purity and biological activity. These can only be attained through in-depth knowledge of the products and of their manufacturing processes. The advanced research here produced will certainly allow the success of therapeutic enzymes production and its easy scalability up to industrial levels at a lower cost. The integrated process developed will have a great impact in economy with a long-term impact in human healthcare. This project aspires the optimization of resources and materials which will contribute to a greener and sustainable growth, which in turn will be a source of economic valorisation for the future industrial manufacturing.

Regarding the candidate:

– Candidate must have PhD in Biotechnology or related disciplines;
– Have completed the PhD no longer than 2 years prior to application;
– Proven international experience in groups outside the institution of origin of the doctorate;
– Excellent early achievement track record (scientific publications and /or patent deposits).
