偷拍偷窥

Science again crisscrosses the Americas this year, as 10 early-career researchers receive travel grants from Promoting Research Opportunities for Latin American Biochemists, a program that helps grantees further their research by working in laboratories in North America. 

Since 2012, the 偷拍偷窥 and 偷拍偷窥 Biology, the and the have given 103 biochemists these awards. The program welcomes applicants from Argentina, Brazil, Chile, Peru, Uruguay, Cuba, Panama, Mexico, Spain and Portugal. Awards support travel and related expenses. 

This year’s PROLAB travel grants go to doctoral students, postdoctoral fellows and early-career scientists from Argentina, Chile, Mexico, Uruguay and Spain. Grantees will work in Canada and the United States. 

The 2023 recipients are: 

Mar铆a Vanesa Amarelle Larrosa

Project title: Functional genomics of alternative SynBio chassis: shortening the gap for developing synthetic biology hosts

Amarelle is a research assistant in the microbial biochemistry and genomics department at the Clemente Estable Institute of Biological Research in Montevideo, Uruguay.  She works on synthetic biology, searching for new biological parts (such as promoters, terminators and coding sequences) and developing a new bacterial chassis. She earned her Ph.D. in basic science development from Montevideo’s University of the Republic.

Amarelle is committed to science outreach and belongs to ComicBacterias, a group promoting microbiology education through comic books. She coordinated two of these: “Bacteria: Lights in the Sky” and “Who Are They? Twelve Uruguayan Women in STEM.” 

Amarelle will work with Federico Rosconi and Juan Ortiz–Marquez in the Microbial Systems Biology Lab at Boston College. The research team offers broad experience in functional genomics, from to CRISPR interference. 

“This grant opens up the possibility for me to enhance my expertise in functional genomics, be trained in cutting-edge technologies and collaborate with a research group with great expertise,” Amarelle said. “It is an incredible chance to not only expand my knowledge but also to make meaningful contributions to the field of synthetic biology.” 

Andrea Celeste Arismendi Sosa

Project title: The effect of dehydroleucodine on mast cell function and responses to Helicobacter pylori infection 

Arismendi works on a research project to combat hunger, “Sustainable Productive and Regional Development to Incorporate Added Value to Dairy Products.” She is a lecturer in microbiology at the National University of San Luis and is studying toward specialization in university teaching at the National University of Cuyo, both in Argentina. She earned her biochemistry Ph.D. at San Luis and then had a postdoctoral fellowship with Alicia Penissi and Alba Vega at the National Scientific and Technical Research Council studying how virgin olive oil combats Helicobacter pylori infections in mice and inhibits H. pylori–induced mast cell activation. 

Arismendi will work with Marianna Kulka, team lead of biomedical nanotechnologies at the National Research Council Canada’s Nanotechnology Research Center. Kulka oversees four laboratories that probe molecular biology, nanomedicine, synthetic organic chemistry and cryogenic electron microscopy.

Cavieres is a postdoctoral fellow in Patricia Burgos’ lab at the Center for Cell Biology and Biomedicine at the University of San Sebasti谩n in Providencia, Chile, where she studies the potential involvement of endoplasmic reticulum quality control in resistance to chemotherapy for breast cancer. She previously served as staff scientist for a project on selective catabolic degradation of the endoplasmic reticulum by an Atg5-independent mechanism. 

Cavieres earned her Ph.D., specializing in cellular and molecular biology, at the Austral University of Chile, in Valdivia. She investigated the role of the GOLPH3 oncoprotein in the function of lysosomes in breast cancer cells, mentored by Gonzalo Mardones.  

Cavieres will work in Juan Bonifacino’s lab at the Eunice Kennedy Shriver National Institute of Child Health and Human Development, which is part of the National Institutes of Health, where she will learn correlative light electron microscopy. 

“This travel grant will provide me with an opportunity to learn a complex technique firsthand, which will greatly contribute to the advancement of my scientific career,” Cavieres said. “It will enable me to implement a novel approach for evaluating cell morphology in Chile.” 

Andr茅s Di Paolo

Project title: Disruption of organelle interaction in the long axis of neurons in vivo and in vitro 

Di Paolo heads the fluorescent microscopy platform while doing postdoctoral work in the genomics department at the Clemente Estable Institute of Biological Research in Montevideo, Uruguay. He studies subcellular localization of protein translation and earned his Ph.D. at Uruguay’s University of the Republic. 

Di Paolo received a 2022 award from the Jacobo and Estela Klip Fund at the Hospital for Sick Children in Toronto, Canada. With that grant and his PROLAB travel award, he will work in Peter Kim’s cell biology lab at the University of Toronto. In 2024, with an Alexander Von Humboldt fellowship, Di Paolo will study with Markus Sauer, an expert in (d)STORM super-resolution microscopy techniques, in Wurzburg, Germany. 

Di Paolo aims to use his training in super-resolved structured illumination microscopy to study the interactions of organelles in axons at basal and injury conditions and bring his skills to Uruguay, which is developing its first super-resolution microscope. 

“Thanks to the PROLAB fellowship and the Jacobo and Estela Klip scholarship, I have the incredible opportunity to learn different super-resolution microscopy techniques and apply them in the study of organelle interactions in axons,” Di Paolo said. 

Mar铆a Victoria Gutierrez

Project title: Effects of nitrolipids on lipid metabolism and scavenger receptor expression in monocytes, and their links to atherosclerosis.

Gutierrez is pursuing a Ph.D. in biochemistry at the National University of C贸rdoba in Argentina while also serving as an assistant professor. She holds a master’s degree in biochemistry with a concentration in molecular biochemistry from the same institution. 

Gutierrez will work in Francisco Jos茅 Schopfer’s lab in the pharmacology and chemical biology department at the University of Pittsburgh. Schopfer’s team discovered nitrated fatty acids in the early 2000s and continues to study their formation and metabolism. Gutierrez hopes to learn more about nitrolipids using new skills in mass spectrometry. 

“The PROLAB program will allow me to boost my knowledge in mass spectrometry techniques and lipid metabolism in monocytes and macrophages,” Gutierrez said. “I am very grateful for this opportunity and think it will greatly impact my academic and personal growth.” 

Susana Guzm谩n Puyol

Project title: Full characterization by solid-state nuclear magnetic resonance spectroscopy of suberin-based films obtained from suberin monomers 

G煤zman is a postdoctoral researcher at the Institute for Mediterranean and Subtropical Horticulture in Spain. As a chemist, she specializes in the production of sustainable packaging from discarded plant biomass. She earned her Ph.D. in nanosciences at the University of Genoa in Italy, with a focus on developing novel bioplastics from vegetable wastes. She holds bachelor’s and master’s degrees from the University of M谩laga in Spain. 

G煤zman will work with Ruth Stark, director of the City University of New York Institute for Macromolecular Assemblies at the City College of New York. They plan to conduct solid-state nuclear magnetic resonance tests of suberin polymers from the epidermal tissues of potatoes, with an eye to developing more bio-based materials. 

“This grant is a fantastic opportunity for my research career,” Guzman said. “The visit to the Starks lab will allow me to learn about cutting-edge characterization techniques of the chemistry behind complex bio-based materials.”
