LNLS USER COMMITTEE ELECTIONS

“I am Atílio Tomazini, a professor at the Institute of Physics of the University of São Paulo (USP), affiliated with the Department of Applied Physics. I hold a B.Sc. in Biomolecular Physics, an M.Sc. and a Ph.D. in Applied Physics, with consolidated experience in structural biology, protein crystallography, molecular biology, and experimental biophysics.

My current research focuses on protein–protein interactions between fasciculin (FAS) and acetylcholinesterase (AChE), emphasizing rational protein engineering, biophysical characterization, and structural analysis of biomolecular complexes. In parallel, I also conduct structural studies of luciferase enzymes, aiming to elucidate the mechanisms of bioluminescence and their applications in biotechnology and bioimaging.

I am a member of the Biological Systems Physics Group at IFUSP, coordinated by Prof. Rosangela Itri, where I participate in projects combining experimental and computational approaches for the characterization of macromolecules and their interactions. Throughout my career, I have collaborated and carried out experimental activities in leading laboratories, including the research groups of Igor Polikarpov, Sasha Popov, David Levin, Mário Murakami, Vadim Viviani, and Júlia Shifman, which have strengthened my background in crystallography, structural biochemistry, and spectroscopy.

I have been conducting research as a user of the Brazilian Synchrotron Light Laboratory (LNLS) and the European Synchrotron Radiation Facility (ESRF) since 2011, employing several techniques for structural characterization of proteins. At LNLS–Sirius, my studies have directly benefited from protein X-ray diffraction (MX) experiments at the Manacá beamline, small-angle X-ray scattering (SAXS) at the SAPUCAIA beamline, and circular dichroism (CD) at the CEDRO beamline. I emphasize the scientific and strategic relevance of these facilities for the continuation and expansion of structural studies of macromolecules and materials in solution, benefiting the entire Sirius user community.

Throughout my academic trajectory, I have sought to integrate physics, biology, and chemistry in the training of new researchers, supervising students at different levels and promoting the use of advanced techniques of structural characterization, particularly those based on synchrotron radiation. I believe that my experience in multidisciplinary and collaborative projects, both in Brazil and abroad, can contribute to strengthening the dialogue between different fields of knowledge within the LNLS–Sirius user community, while also enhancing the interaction with laboratory researchers to represent the community’s scientific needs effectively.

I am applying to the LNLS User Group with the purpose of fostering integration between applied physics and life sciences, promoting the continuous improvement of technical and

scientific support, the training of new users, and the active representation of the scientific community in the laboratory’s strategic decisions”

“My name is Diego Germán Lamas, from Buenos Aires, Argentina. I am a Principal Researcher at the National Scientific and Technical Research Council of Argentina (CONICET) and Associate Professor at the Universidad Nacional de San Martín (UNSAM). I founded and currently direct both the Instituto de Tecnologías Emergentes y Ciencias Aplicadas (ITECA) and the Laboratorio de Cristalografía Aplicada (LCA), focused on laboratory and synchrotron X-ray studies of nanostructured materials and functional ceramics. The LCA is an open-access facility for the scientific community, equipped with a powder X-ray diffractometer and a small-angle X-ray scattering (SAXS) instrument that also allows simultaneous wide-angle (WAXS) measurements. I have a Ph.D. in Physics (University of Buenos Aires, 1999) and over 30 years of experience in applied crystallography and materials for clean energy, particularly solid oxide fuel cells (SOFCs). I am author of 132 international papers (Scopus h-index = 26, >2800 citations), have led numerous research projects, and have supervised or co-supervised 11 PhD, 1 Master’s, and 8 undergraduate theses, as well as 5 postdoctoral fellows and 3 assistant researchers. I served as President of the Argentine Crystallographic Association (AACr) from 2011 to 2014, and of the Latin American Crystallographic Association (LACA) from 2016 to 2018. I was Chair of the Organizing Committee of the Argentinian Crystal Growing Competition for High Schools from 2014 to 2019, during which I organized more than 250 short courses on Crystallography and Crystal Growth, covering all provinces of Argentina. I currently serve on the International Union of Crystallography (IUCr) Teaching Committee and am a member of the Regional Committee for South America of the LAAAMP Project (Lightsources for Africa, the Americas, Asia and the Middle East Project), an IUCr–IUPAP initiative that promotes access to synchrotron light facilities in developing regions. I have been a frequent user of the LNLS since 2003, mainly performing experiments at the X-ray diffraction and X-ray absorption beamlines, and have taught numerous courses on Crystallography and X-ray/synchrotron-light techniques across Latin America. I am deeply committed to expanding and strengthening the Latin American synchrotron user community, and I would be honored to collaborate within the Users Committee of the LNLS Users Group.”

“I hold a B.Sc. in Industrial Chemistry and an M.Sc. in Chemistry from the Federal University of Rio Grande do Sul (UFRGS), and a Ph.D. in Biomolecular Chemistry from Université Paul Sabatier – Toulouse III (France). I am currently a Full Professor at UFRGS (in the Department of Inorganic Chemistry), Coordinator of the PRH50/UFRGS Program in Petroleum Chemistry and Clean Energy, and President of the Brazilian Society of Catalysis (SBCat).

My research focuses on the development of heterogenized catalytic systems, homogeneous and heterogeneous catalysis, nickel complexes, ionic liquids, zeolites, MOFs, and CO₂ conversion processes. I employ synchrotron-based techniques for structural and mechanistic studies of catalytic materials.

As a member of the Users Committee, I aim to strengthen communication between LNLS and its user community, facilitating researchers’ interaction with the laboratory, and promoting scientific excellence and the continuous advancement of the facility.”

“Sou Professor Associado do Instituto de Química da Unicamp e lidero o Campinas Electrochemistry Group (CampEG). Minha formação é em Química (UNLP, Argentina) e doutorado em Nanotecnologia (INIFTA/CONICET, 2011). Atuo na área de Eletroquímica e Eletrocatálise, com forte ênfase em técnicas in situ/operando (FTIR, Raman, XAS e XRD), tanto como usuário quanto no desenvolvimento de setups e metodologias para experimentos eletroquímicos in situ. Nos últimos anos, temos estendido algumas dessas abordagens a outras áreas da ciência. No contexto desta candidatura, é relevante destacar minha atuação recente também na área de termocatálise.

Nosso grupo tem realizado medidas in situ em diversos síncrotrons internacionais, incluindo Max IV (Suécia), ESRF (França), SOLEIL (França) e Diamond (Reino Unido), sempre buscando integrar instrumentação avançada e investigação fundamental de interfaces (eletro)químicas. Tenho grande interesse em atuar de forma ativa na representação da comunidade usuária do LNLS, contribuindo para aprimorar o treinamento em boas práticas na elaboração e execução de propostas, de modo a otimizar o uso do tempo de linha e ampliar o impacto científico das pesquisas. Acredito que fomentar a integração entre usuários novos e experientes, assim como impulsionar ações que promovam maior acesso, diversidade e qualidade dos experimentos, é essencial para fortalecer nossa comunidade e maximizar o potencial do LNLS.”
