Welcome students

On behalf of the Laboratory, I welcome you here and hope you have a safe and rewarding experience. The Laboratory has many programs and procedures in place to ensure your health and safety. Your mentor is responsible for working with you to make sure that you are aware of the hazards of your work and the controls required to protect you. You are responsible for following the requirements that apply to the work you are assigned, including completing any required training. Your mentor also should inform you of the requirements for reporting any problems, injuries, or illnesses.

An important thing to keep in mind is that if you have any doubt about your safety, stop what you are doing and notify your mentor. You also need to be aware that your actions can affect the safety of your coworkers and others, so integrate safety into everything that you do, including your commute to and from the workplace.

I encourage you to use the many resources available to you as a Laboratory employee to keep you safe and healthy. These include your mentor, your worker safety and security team representative, deployed Industrial Hygiene and Safety personnel, and Occupational Medicine. They can provide you with general information or information specific to the work that you have been assigned. If you don’t know who to call, you can call the Safety Hotline at 5-SAFE (7233) or send an e-mail to safety@lanl.gov.

I sincerely hope that you enjoy your experience here at the Laboratory and that you leave here with some valuable knowledge and skills, including safety skills, that you can apply in your future endeavors.

--Chris Cantwell, associate director for Environment, Safety, Health, and Quality

Plesko lauded for Outstanding Paper

Catherine Plesko won an Outstanding Student Paper Award at the American Geophysical Union Fall Meeting in San Francisco. Plesko’s paper was recognized among the best of a strong group of student presenters.

Plesko studied the formation of large-impact craters on Mars using high-performance computers and the Crestone RAGE hydrodynamics code at LANL. The study addressed how asteroid or comet impacts may have warmed the Martian climate and altered the nearby landscape. Substantial evidence exists that liquid water was once present on the surface of Mars at a time when the sun was too faint to make the planet surface warm enough. Large-object impacts may have triggered Martian climate change early on. Plesko and her scientific collaborators modeled the impacts on the Martian surface as it was believed to have existed 3.5 billion years ago.

The award-winning paper is the basis for Plesko’s doctoral dissertation at the University of California, Santa Cruz.

Plesko came to the Lab in 1997 as an Earthwatch Challenge Award student. After doing periodic summer research at the Lab, Plesko, along with her colleagues and advisor, received a minigrant from the Institute of Geophysics and Planetary Physics to study large-impact collisions. Plesko has been a graduate research assistant in Applied Physics Division since 2007 and will defend her thesis soon at UC Santa Cruz.

Rosev paper wins social science award

Tatjana K. Rosev of the Communications Office recently won Top Graduate Paper for her research “Reaching for the Stars: Acculturative Experiences of German Sojourners on a Southwestern Air Force Base.” She received a certificate and $500 at the 2009 Western Social Science Association conference in Albuquerque.

Rosev, who holds a German graduate degree in law, completed her master’s degree in communication at the University of New Mexico while working at the Lab and was named valedictorian of her class. This fall she will begin her doctorate in communication at UNM.
