Reveal from The Center for Investigative Reporting is adding four new members to its staff.

Fernando Arruda is our new associate sound designer and engineer. A native of Brazil, Arruda has spent the last decade working in music and sound in New York City, most recently through the Manhattan Composers Collective, an audio postproduction company he founded. He’s taught Pro Tools and audio postproduction as well. He’s composed ad spots at Antfood, taught music technology at Dubspot, toured as an international DJ and did some sound design for a virtual-reality version of Marvel’s “Avengers: Age of Ultron.” At Reveal, Arruda will work with lead sound designer and engineer Jim Briggs, adding another musical voice for the radio show and podcast with his scoring abilities.

Anayansi Diaz-Cortes has come on board as a radio reporter/producer. Diaz-Cortes’ work has been featured everywhere from All Things Considered to Radio Ambulante and This American Life. She recently produced a pilot called “Club America” for Audible and was the co-creator and lead producer of Sonic Trace, KCRW’s storytelling project. Diaz-Cortes has done extensive work reporting in both the U.S. and Mexico. With the help of Columbia University’s Center for Spatial Research, Sonic Trace collected data on the connection of every neighborhood in Los Angeles County to villages, town and cities south of the border. For a Radio Diaries piece that aired on All Things Considered, she dug into the history of the October 1968 massacre in Mexico, where police officers and military troops shot into a crowd of unarmed students ahead of the Summer Olympics.

Aura Bogado will join us in early February to cover immigration as part of the investigative reporting team. She currently works as an independent journalist, writing for Mother Jones, The Guardian and The Intercept, among others. She is particularly interested in the overlap between immigration and environmental justice and has written extensively about both. In one piece for The Intercept, she traced the unintended consequences of California Gov. Jerry Brown’s sanctuary policies, uncovering ways that they could open up new lines of communication between Immigration and Customs Enforcement and local jails. Her most recent staff job was at Grist and she previously worked for Colorlines and The Nation. Bogado is an immigrant herself and a native Spanish speaker, with basic skills in four other languages, including Guarani and Jopará.

Elizabeth Shogren also will join us next month as our first Washington, D.C.-based science reporter. Shogren comes to us from High Country News, where she has written long-form narratives, investigations, news and analyses about Washington’s impacts on the American West. As an on-air correspondent for National Public Radio from 2005 to 2014, she worked for both the national and science desks. She covered the BP oil spill and was a lead reporter for Poisoned Places, an award-winning series about toxic air pollution. Previously, Shogren was a national correspondent for the Los Angeles Times, where her beats included the White House. One scoop was an unscheduled interview with President Bill Clinton the day after the House voted to impeach him. She also was a Moscow correspondent for the paper and covered the Kosovo refugee crisis and U.S. troop deployment in Bosnia.
