New Employee Profiles - May 2017

May 1, 2017

Gonzalo P. Rodrigo Álvarez, CRD


Gonzalo P. Rodrigo Álvarez

This month, Gonzalo P. Rodrigo Álvarez joins CRD’s Science and Technology Department as a postdoctoral fellow. Initially, he will be working with domain scientists and NERSC staff on the Science Search project to create new methods for sifting through massive scientific datasets. The collaboration works with domain scientists to figure out their search needs, then applies machine learning tools to classify and identify datasets using their environment information as a source of metadata (e.g., the code of the application that generated the dataset).    

Rodrigo may be a new employee, but he is no stranger to Berkeley Lab. In fact, he spent the last three years working on and off in CRD’s Data Science and Technology Department. For six months in 2016, he worked at the Lab investigating supercomputing scheduling models, including workload analysis and performing scheduler simulations. For six months in 2015, he was an intern working on workflow task managers and workflow scheduling. And for five months in 2014, he was a visiting scholar that helped analyzing the workloads of the three NERSC systems of the time: Edison, Hooper, and Carver. He also spent some time as a Google intern working with large-scale data processing workflows and steaming pipelines; as well as four years as an R&D engineer at a network equipment manufacturer, where he learned about network protocols, transport technologies, embedded systems, and industrial software development.

“When I was six years old, I learned to draw paper boats using ‘prints,’ ‘asterisks,’ ‘space’ and a BASIC interpreter in a green screen Amstrad PCW 8512 personal computer that my parents bought for work,” says Rodrigo. “Those days were the beginning years of my amateur, professional, and scientific relationship with computing.”

Originally from Zaragoza, Spain, Rodrigo didn’t stray far for college. He earned both his Bachelors and Masters degrees in computer engineering from the Universidad de Zaragoza, located in his hometown. He would later move to Sweden to purse a PhD in computer science from Umeå University. Lavanya Ramakrishnan, who leads CRD’s Usable Software Systems Group, served as co-supervisor of his thesis, along with Umeå University Professor Erik Elmroth.

In his spare time, Rodrigo likes to camp, hike, ski, travel and play music. As a new resident of the Bay Area, Alvarez also plans to attend a lot of concerts.

Sartaj Baveja, ESnet


Sartaj Baveja

As ESnet’s newest Junior Software Engineer, Sartaj Baveja will be developing software to support the network’s operations. He is currently working on a Google Cloud Dataflow pipeline that will process large quantities of time-series data and provide network statistical analysis. Baveja is also working on MyESnet, an interactive network portal monitor network performance in real time.

Although Baveja officially joined ESnet as staff this month, he is no stranger to the organization. As an ESnet Software Engineering Intern in 2015, he implemented a time-series analytics engine that generated 60 percent performance improvement by parallelizing and batching database writes. And last summer while interning at CERN, Baveja helped evaluate the capabilities of Oracle’s lightweight data-interchange format, Javascript Object Notation (JSON), and compared its capabilities with the widely used MongoDB. 

He notes that his interest in building software sparked during his sophomore year of college when he worked at a healthcare startup called Buzz4Health. This was where he got to build his first mobile app from scratch and he’s been hooked ever since. In fact while he was interning at ESnet, Baveja participated a hackathon sponsored by Chime for Change, a global campaign to raise funds and awareness for girls and women around the world. It was his first hackathon and he helped develop an app called “Safrzone,” which was designed to help improve safety for women and girls.

"Being my first hackathon, I was looking forward to code and develop a technical solution to promote safety for girls and women across developing countries like India, students across campus, and women facing issues such as domestic violence," says Baveja.

Born and raised in India, Baveja completed earned his undergraduate degree in Engineering from the Netaji Subhas Institute of Technology (NSIT) in Delhi, India. In his spare time, he enjoys playing musical instruments, tennis and reading up on the latest tech news.  

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
