Navarro attended Texas A&M University, financed through a League of United Latin American Citizens (LULAC)/Salvation Army scholarship, loans, grants, and support from a lawn-mow- ing business he started with his father, who urged him to pursue electrical engineering. Julio joined Texas A&M University’s co-operative education program and began work with General Dynamics - Fort Worth Division (now Lockheed Martin). In 1988, he was selected for the graduate co-op program and found his calling in RF circuit and antenna design. He also pursued a master’s in electrical engineering at Texas A&M. Upon graduation, he was awarded a National Science Foun- dation Fellowship to pursue a Ph.D. in electrical engineering. This award was followed in 1993 by a NASA - Lewis Training Award. In 1994, he got married and moved from Houston to Ge-

Dr. Diggs is also an excellent mentor for the youth in his

community. He uses his professional platform to encourage disadvantaged youth to pursue careers in science, technology, engineering, and math (STEM). He does this by mentoring high school, undergraduate, and graduate students; tutoring Upward Bound and Wright-STEPP students; and motivational speaking across the nation.

neva, Illinois, near Chicago to work at Epsilon Lambda Electron- ics Corp. In 1996, Dr. Navarro was hired by Boeing to design, build and launch the Teledesic program, a global phased-array satellite network. Since then he has contributed to many winning proposals resulting in multi-million dollar phased-array contract awards.

Navarro has been honored for his technical contributions with several awards including the GMiS Outstanding Technical Achievement in 2011, SHPE Hispanic Technical Achievement in 2008, and HENAAC Most Promising Engineer in 2001. Boe- ing honored Navarro with three Special Invention Awards in 2001, 2005 and 2012 for specific technical accomplishments that advanced the field of phased-array antennas.

Jin Wang, Ph.D Director, New Technology Engineering AT&T


in Wang is a graduate of both Bejiing University and University of California at Berkley (UC Berkley). Dr. Wang earned both his bach- elor’s of science and master’s of engineering in telecom- munications and information systems while attending Beji- ing University. He completed his Ph.D while attending UC Berkley.

Going on 10 years with AT&T, Dr. Wang is currently

director of new technology product development engineering in the radio access, analysis and devices department. As a director in radio access, analysis and devices team, Jin Wang has a wide range of responsibilities that include performance analysis, op- timization and troubleshooting of AT&T’s mobility and wireline networks, as well as employee coaching and development. His main area is access network and home network, but end-to-end service quality assessment and troubleshooting is becoming an essential part of daily job. As an added responsibility, Jin Wang manages an UMTS/LTE toycell lab and supports operation tool- ing with data validation and prototype assessment. Dr. Wang’s work has resulted in over 20 US patents in network engineering, management, troubleshooting and optimization. Several have evolved into mobile/web tools used by thousands of engineers and technicians in AT&T. Dr. Wang is a long-time participant in professional organiza- tions such as IEEE communications society. He also supports groups such as Cal State east bay job panel and UC Berkley Chinese student and scholarship association.
