GHC18: LLNL presenters and participants

Many LLNL women and allies attend Grace Hopper Celebration every year to learn, to network, and to be inspired. They also recruit new folks to support our mission: science in the public interest.

Two of this year’s attendees were recruited at a previous GHC, and we’d like to share their stories to encourage other GHC attendees to come visit our booth and talk to our knowledgeable and approachable staff.

LLNL recruiters discovered Amanda Minnich through GHC’s resume database. She interviewed at the conference and could quickly tell it was a good fit. Amanda joined the lab as a staff scientist in July 2017. ”Now I apply my machine learning skills to optimize drug discovery,” says Amanda. “I am so grateful to GHC for connecting me with my dream job!”

At previous career fairs and conferences, Waverly Roeger had talked to many recruiters without really connecting. At last year’s Grace Hopper Celebration, something clicked. “The people at the LLNL booth made genuine conversation, talking about important and interesting work going on at the Lab, the diversity of the work, the diversity of the people, and the work-life balance,” noted Waverly. “At GHC, the environment is built for success and support, and I was already at peak confidence and enthusiasm for my impromptu interview/prolonged-conversation which catapulted me through the hiring process.” 

At GHC17, Waverly and Amanda encouraged others to join them in using their computing skills to meet our important mission. Here’s what Waverly had to say about her time behind the booth:

This year I was lucky to join LLNL women at #GHC17, and I was again blown away by their character, warmth, joy, and overwhelming generosity. Being on this side of the booth, I got a much more in-depth view of my chosen home, and I can reaffirm my initial impression on the culture at the Lab. I’m so happy to be a part of this family and trying my best to channel all of the good qualities these women emanate, and I’m excited to grow alongside them. —Waverly Roeger

We hope to see you at #GHC18!

Our Presenters

Ashka Shah

Addressing challenges in developing Virtual Beamline (VBL): a large-scale,
high-energy parallel laser simulation code

Poster Session
Friday | 9-11:30am | GRB Exhibit Hall D

Modeling of advanced laser systems requires massively parallel simulations with
multi-order increases in time/space resolution compared to Virtual Beamline’s (VBL)
current capabilities. In developing the new version of VBL we address two key
challenges: heterogeneous parallel computing using MPI and RAJA, and coordinating
a large-scale scientific software project with a Scrum Agile approach.
