“The more I learn, the more I realize how much I don’t know. This is a fun industry. It gets in your blood and you just stay.”

Robyn got her start in the travel industry when a college advisor told her about a job with Avis Rent a Car at a local airport. After falling in love with the industry, she moved to Dallas and got a job with American Airlines. When the Internet emerged, Robyn experienced her first taste of product development and became a part of the team that brought AA.com online. From that point forward, Robyn has been focused on innovating and creating new norms in the travel industry, whether she was launching Travelocity.com or developing products at Sabre. She considers herself an 'official dot connector' who loves to challenge the status quo.

“Aviation is unique. It’s a global industry, and yet we are all working together toward a common desired outcome. I can’t imagine working in any other industry.”

Growing up, Andrew wanted to be an airline pilot like his father, but color blindness prevented him from pursuing this dream. Even still, Andrew continued to follow his passion, getting a degree in aerospace engineering and working as an aviation journalist for over 20 years. In 2004, Andrew transitioned from editorial work to helping develop data solutions, drawing on his vast industry experience to solve customer problems. When he isn’t sharing his knowledge with his colleagues, Andrew enjoys sailing, running and cycling.

“You learn something new every day by digging in and learning about the peculiarities of data.”

Prior to joining Cirium, Mary developed software for mobile experiences and built predictive 'recommended for you' capabilities on retail websites. As someone who works with engineers every day, Mary believes that to make a good product you need to fail fast, fix things and get back out there. As a program manager at Cirium, Mary was responsible for on-boarding flight status and operational data from airlines, which taught her about the nuances of how the industry records information across the globe. When she isn’t managing engineers, Mary enjoys riding her bike.

“It takes millions of smart people all over the world to make air travel happen. We get to enable that with data and hopefully help people do their jobs better.”

A homegrown aviation enthusiast, Michael has been a software engineer in the industry for nearly 20 years and got his start as one of the original team members of FlightStats, now Cirium. He describes his job as 'philosophy plus LEGOs' since it allows him to tinker with technology and work closely with people. Michael enjoys helping customers and colleagues find the simplest solution to complex problems. When he isn’t riding his skateboard around the office answering various technical questions, Michael likes to spend time with his son.

“I love the people. I have friends in this industry that I’ve known for 30 years. I’ve never known anything else.”

Joel always thought he would be a lawyer. Instead, he has spent the past 30 years cultivating a career in the aviation industry, which began when a friend got him a job as a baggage handler. By 1993, Joel found himself at U.S. Airways working as a director of network planning. After spending 10 years with the airline, Joel moved on to an airport consulting firm, Seabury APG. As a specialist in how airlines and airports use traffic, fares and schedules information, Joel became part of a team that was building a new data tool called Diio. When he isn’t solving problems for airlines and airports, Joel likes to be with his family and spend time outside.

“Data science is asking and answering questions. People come to us with a question and we experiment to see what we can and can’t do with the data we have.”

Kate has been working in data science for two years and experimentation is why she loves her job. Although Kate originally earned a Ph.D. in Astrophysics, the skills she learned in school are similar to those she employs as a data scientist. As a student of astronomy and physics, Kate frequently worked with large data samples, transforming raw data into explorable information to answer specific questions. When she isn’t digging into data, Kate enjoys learning new languages, including British Sign Language and Italian.

“We’re very proud of having the best, most accurate data available. My mission is the make sure our data is the most accurate out there.”

John is a true lover of aircraft. In fact, you can find him outside looking for aircraft and taking photos when the weather is right. His passion for aviation stems from being raised by a father in the Royal Air Force and frequently attending airshows as a child. John joined Ascend Consultancy almost a decade ago, specializing in helicopter data. Since then, John’s love of aviation hasn’t waned, and he widened his score from helicopter data to being responsible for all of Cirium’s fleet data sets.

Rob began his career in aviation in May 1990 as a marketing executive at British Aerospace. Prior to joining Ascend By Cirium in 2012, Rob was Vice President, Marketing & Analysis at BAE Systems Asset Management.

“For most people in this industry, aviation was a passion before it was a profession. It’s more like a family than a profession.”

Kevin is a person who loves change, which explains why he has held several positions at FlightGlobal. Following his graduation from law school, Kevin decided to become a journalist rather than a lawyer. He was the first ever business editor of Flight International, where he helped establish regular coverage of the airline and aerospace industry. He then spent several years leading Airline Business before taking up a strategy position in mid-2005. With decades of experience reporting on the industry, Kevin is a frequent commentator on international media, including BBC and CNN news, and regularly speaks at events. In his spare time, Kevin enjoys spending time watching the West Ham United Football Club with his son.
