DR. Steven Cliff is the Deputy Administrator of the National Highway Safety Administration (NHTSA). He talks with Mark about the importance of Vehicle Safety Week.Vehicle recalls keep our roads safer for everyone!About Dr. Steven Cliff, Deputy Administrator of NHTSA: He oversees the nation's vehicle safety agency that sets vehicle safety standards, identifies safety defects and manages recalls, and educates Americans to help them drive, ride, and walk safely. NHTSA's work also includes establishing fuel economy regulations and helping facilitate the testing and deployment of advanced vehicle technologies. The agency has a budget of more than $1 billion and more than 600 full-time employees across the country. Cliff brings an extensive scientific and regulatory background to his leadership role at NHTSA. Most recently, he served as the deputy executive officer at the California Air Resources Board, an organization he first joined in 2008 as an air pollution specialist. Since then, he held a variety of positions at CARB, eventually overseeing its climate program. From 2014 to 2016, Cliff joined the California Department of Transportation as the assistant director for sustainability. He returned to CARB in 2016 when then-Governor Jerry Brown of California appointed him senior advisor to CARB's board chair.  Cliff's most recent work as deputy executive officer at CARB included program oversight of regulations for passenger vehicle emissions, medium- and heavy-duty engine emissions, implementation of vehicle and engine emissions and on-board diagnostics certification, transportation land-use planning and analysis, and incentive and investment programs for reducing emissions. He worked with environmental and equity advocates, senior industry officials, association representatives, and other stakeholders on program development. Cliff played an active role at the University of California, Davis for nearly two decades. In 2001, he joined the school's Applied Sciences department as a research professor, later becoming affiliated with the school's Air Quality Research Center. Through the years, he has supported independent air quality and climate research programs while balancing his time at CARB, including being an approved program coordinator at the Lawrence Berkeley National Laboratory's Advanced Light Source. Cliff received a bachelor's degree and a doctorate in chemistry from the University of California, San Diego. He then completed a postdoc on atmospheric sciences at the University of California, Davis' Department of Land, Air and Water Resources. https://www.nhtsa.gov/recalls

Grad students in hard sciences are often made to believe that their career options post-graduation are limited to research positions in academia, industry, or national labs. However, the skills one develops during a PhD program are transferable to more job types and settings than expected. In this episode, we talk with Dr. Ashley White, who currently works at Lawrence Berkeley National Lab as both the Director of Communications for the Advanced Light Source and the Head of Strategic Development for the Energy Sciences Area. She discusses her non-traditional career path, difficult decisions she has had to make, and how the skills she has learned along the way make her uniquely qualified in her current job. We'll talk about the importance of her role at a national lab and a little bit about what kind of research actually goes on at LBNL.

En este nuevo capítulo tenemos como invitada especial a Pia Valdivia, investigadora en el campo de la física de plasmas. Graduada de la Universidad Católica de Chile con un doctorado en Física en Ciencias Exactas. Pia ha participado en investigación en el CERN, trabajó para la compañía nanoUV en París y también en la École Polytechnique, donde trabajó en laser LULI2000 y realizó una pasantía en Northwestern University trabajando en dos sincrotrones: Advanced Light Source y Advanced Photon Source. Ahora se encuentra trabajando para la Universidad de Johns Hopkins donde está a cargo de dos grandes proyectos en el tercer láser más potente de EEUU y además participa de otro proyecto en potencia pulsada en la Universidad de California San Diego. Su investigación se enfoca en el desarrollo de diagnósticos de imágenes de rayos-x para el estudio de plasmas de altas densidades y energías (HEDP). Además de su investigación, Pia participa en proyectos y actividades de divulgación de ciencias. Uno de sus favoritos son los Clubes de Ciencia donde participa enseñando física básica a través de experimentos caseros, muy entretenidos, para demostrar que la física no solo está presente en todo lo que nos rodea sino que también ¡nos pertenece a todos! --------------------------------------------------------------------------------- Anfitriones: Ricardo Cavieses y Claudia G.

Sophia Chen of MRS Bulletin interviews Alex Hexemer of Lawrence Berkeley National Laboratory in California, and Daniela Ushizima and Shuai Liu of the University of California, Berkeley about their design of multiple Convolutional Neural Networks (CNN) to classify nanoparticle orientation in a thin film by learning scattering patterns. Read the article in MRS Communications. Transcript SOPHIA CHEN: Materials researchers come from around the world to study their samples in the beamline at the Advanced Light Source facility, located at Lawrence Berkeley National Laboratory in California. Alex Hexemer, a senior scientist at the facility, tells me that they’re currently upgrading the machine, so that it can take much more data, much more quickly. HEXEMER: The amount of data you’re going to create is so large that A, you can’t take it home on a hard drive anymore, nor can you start looking at the data anymore. It’s just too big. Some of the detectors here are going to run at thousands of frames a second. It becomes unmanageable from a human point, so we have to transition to more automated approaches.CHEN: So Hexemer and his collaborators decided to try a machine learning approach to quickly classify and process x-ray images. To develop their image classification algorithm, they worked with frequency-space pictures of thin films made of polymers, about 100 nm thick. Scientists image these thin films at the facility. They consist of intricate geometrical patterns on the nanometer scale, which researchers try to engineer to create specific materials properties. For example, Hexemer explains that one future application is a printable solar panel. In the future, people might be able to print photovoltaics made of thin film polymers. But first, they need to figure out what nanometer structures work the best.HEXEMER: To try to understand the efficiency of the material, we have to understand the morphology.CHEN: They came up with seven different categories of thin film patterns. One of Hexemer’s computer science collaborators, Dani Ushizima, explains that they had to show the computer millions of examples.DANIELA USHIZIMA: This neural network base will build a mathematical model that will represent the different patterns.CHEN: They found they could classify images successfully into the seven categories 94% of the time. USHIZIMA: The training process might take a long time—hours. But the feedback, to classify a scattering pattern, this is coming on the millisecond. CHEN: The images they classified were simulations of thin films rather than real data. HEXEMER: We want to have better and better simulations close to real and partially disordered systems. And that is very difficult. CHEN: The team brought together experts from materials science and computer science. Shuai Liu, a member of the team, says to expect more collaborations between the disciplines.SHUAI LIU: We point out a very important direction in future research is to combine machine learning, which has been well developed in recent years, with a lot of characterization techniques.CHEN: My name is Sophia Chen from the Materials Research Society.
