Prior to her career in the Air Force she worked at NASA’s Johnson Space Center in the Space Shuttle Flight Training Division, Mission Operations Directorate.
Tia is a Fellow by the Society for the Advancement of Material and Process Engineering (SAMPE), an International Past President of SAMPE, and was President of the Materials Research Society (2014). She is the BCA Executive Sponsor for Boeing’s SAMPE External Technical Affiliation as well as Edmonds Community College. Serves on Iowa State University’s Aerospace Engineering Department’s Industry Advisory Council, University of Washington Materials Science & Engineering Department’s Industry Advisory Council, and is a Trustee of Edmonds Community College.
Mary Cardenas is the LaFetra Chair in Environmental Engineering at Harvey Mudd College (HMC is a highly-selective, private college of engineering and science in Claremont, California). She was the first female engineering professor at HMC. Her industrial experience includes propulsion engineering at Rocketdyne, where she worked on the Space Shuttle Main Engine, Atlas, and the National Aerospace Plane (X-30). She was a research scientist in environmental engineering at National Oceanic and Atmospheric Administration (NOAA), and Sandia National Laboratories. She revised, updated, and enlarged the book, “Modern Engineering for Design of Liquid-Propellant Rocket Engines” (Huzel and Huang).
As an educator, she focuses on hands-on, project-based undergraduate engineering education, and was co-designer of the sophomore-level model-rocket-based experimental engineering course, and the first-year Studio Methods Engineering Design course. She has supervised undergraduate research projects on marine hydrokinetic turbine modeling; groundwater modeling for nuclear repositories; contaminant fate and transport in the Great Lakes; and model rocketry data acquisition.
She is currently a Division Director for the Environmental Engineering Division (EED) of the American Society for Engineering Education (ASEE), and has served at HMC as Associate Dean for Academic Affairs, and as the Engineering Clinic Director. She received her B.Sc in Aerospace and Aeronautical Engineering from Iowa State University (1987), and her M.Sc. (1993) and Ph.D. (1994) in Mechanical and Environmental Engineering from the University of California, Santa Barbara.
Kevin Gordon is the Senior Director, Product and Application Lifecycle Management, Collins Aerospace. He leads a Collins wide effort to improve process effectiveness throughout Collins by harmonizing Product and Application Lifecycle Management processes, partnering with all Collins Strategic Business Units and Functional Groups. Kevin is responsible for leading Collins ALM and PLM strategies including PLM Implementation. This includes implementation of all applicable PLM processes, using Teamcenter, from requirements definition, solution design, and implementation. This system delivers a collaborative and compliant common environment, creating financial benefits to the company by harmonizing engineering and operations systems in support of an overall digital strategy. Kevin started his Collins Aerospace Systems career in 1996 as a Sr. Project Engineer, and has held positions of increasing responsibility providing leadership in engineering, quality assurance and SAP. His most recent positions were Sr. Director for Advanced Technology and co-leading the largest SAP transition in UTC. He also led the working teams creating the initial UTAS digital strategy vision. Prior to joining UTC, Kevin was a project engineer at McDonnell Douglas and Boeing.Kevin holds a Bachelor of Science degree in Aerospace Engineering from Iowa State University and a Master of Engineering Management from Washington University in St. Louis, MO.
Jeremy Hollman has worked in the aerospace engineering field since 2000 and for Scientific Systems since 2016. His areas of technical experience include testing design and execution for autonomous systems, liquid rocket engine, propulsion system, and fluid component design and development, general fluid dynamics, and thermal management design and analysis, along with general program and project management.
Since joining Scientific Systems he has been involved with the demonstration of the ImageNav system as a means for GPS denied navigation for vehicles. At Aurora he was the lead propulsion engineer for the DARPA Rapid Eye aircraft and Vulture aircraft, performed cycle analysis, and design and trade study activity on a variety of proposed engine concepts in support of other programs, as well as supporting the NASA N+3 program in Phase 1 as Aurora’s PM and then Co-PI in Phase 2. In addition to these activities he has served as the IPT lead for the VTOL X-Plane Power Generation system under a DARPA contract and PI/PM on a variety of other SBIR/STTR programs for NASA and the US DoD. He served as the Chief Engineer on an Office of Naval Research Autonomous helicopter program to deliver aerial cargo for the Marines (AACUS). He served as the Director of Aerospace Systems and Directed several groups of researchers at Aurora’s Research and Development Center in Cambridge, MA working on developing, analyzing, and integrating aerospace systems.
Prior to moving to the east coast he worked for Space Exploration Technologies, and the Boeing Company in Southern California. He was involved in SpaceX from the beginning, helping to develop, test, qualify, and launch the company’s family of launch vehicles. He joined the company in 2002 when it was made up of less than 20 people and helped to grow the company to over 400 employees and a successful launch of the the Falcon 1 vehicle. At SpaceX Hollman was the director of propulsion development, which oversaw the design, development, and production of the Merlin engine. He also served as the responsible engineer for the Falcon 1 vehicle supporting the launch operations team at the range during assembly checkout and launch activities. He worked with his team to design and develop a variety of fluid flow components including but not limited to check valves, ball values, hydraulic actuators, vent/relief values, and butterfly valves for fuel and cryogenic service, developing, qualifying, and eventually flying, on the Falcon 1 flight vehicle.
He currently holds three patents ranging from high altitude combustion systems to small-unmanned aerial vehicles. In 2012 he was one of ~100 engineers and researchers from across the United States invited to participate in the National Academy of Engineering’s Frontiers of Engineering Symposium and also attended the EU – USA forum in 2014 as one of ~65 engineers and researchers to participate in that event.
Steve is a member of ASME, AIAA and RAeSoc and has received several team and individual awards, including the Royal Aeronautical Society Gold Award in 2008. Steve is currently the Head of Aerothermal and Functional Design for Civil Aerospace and is a Rolls-Royce Senior Fellow in Turbomachinery Systems.
