9am – Room 220A

Welcome Keynote

The Devoxx US welcome keynote includes practical information about the event.

Mike Milinkovich is executive director at the Eclipse Foundation.

Outside of work, Mike’s passions are his family, the family cottage and hockey (as a coach, player and fan) in pretty much that order. When he’s not working, or traveling for work, you will probably find him involved in one of those three things.

Stephan Janssen is a serial entrepreneur who has founded several successful organizations such as the Belgian Java User Group (BeJUG), JCS Int., JavaPolis/Devoxx,, Devoxx4Kids, and co-founded

He has been using Java since its early releases in 1995 with experience in developing and implementing real world Java solutions in the finance and manufacturing industries.

In 2005, Sun Microsystems recognized his efforts for the Java Community and engaged Stephan in the Java Champion project. He has spoken at numerous Java and JUG conferences around world and has received the JavaOne Rock Star and Duke’s Choice awards.

Tuesday: Chet Haase
9:20am – Room 220A

The Business of Technology Business Technology

Technology is really important. So is business. So the business of the technology business technology is even more so. This talk will convince you that you need to hire me to help you navigate these wet, wet waters.

Chet leads the Android UI Toolkit team at Google, where he works on animations, graphics, UI widgets, and anything else that puts pixels on the screen. He also writes and performs comedy if given the chance or a mic.

Janelle is an artist of paint, music, and software who uses software as a metaphor for life.  After researching “Idea Flow” (, Janelle turned into a hobbyist cognitive scientist, obsessed with understanding brains. Right now, she’s working on building a human brain simulator based on her research that will be the core tech behind her new venture, Open Mastery (

Aside from Open Mastery and brains, Janelle is a NFJS tour speaker, and for the last 15 years has been a developer, consultant, and CTO. Her focus has been data-intensive analytic systems, Continuous Delivery infrastructure, database automation, test automation strategies, and helping companies identify and solve their biggest problems.

What Is Identity?

Imagine your brain’s logic is written in code. You fire up the debugger, set a breakpoint in the “Identity” class, and inspect your brain’s internal state. What are the state variables? What does the code look like? How do we fix the bugs?

In this talk, we’ll explore brand new territory — how to use software as a metaphor to understand the human brain. You’ll learn a new language of metaphorical shapes to describe the “Architecture of Identity,” then we’ll examine some of the key dysfunctions in our organizations through this lens.

As engineers, we pour our hearts into our work, and our creation becomes an extension of ourselves. As a team, we turn into a family, raising a child, and we dream about how our baby will grow up to be beautiful and awesome. We sacrifice ourselves for the well-being of our child, because it’s pre-wired into our DNA. Unfortunately, when our beautiful creation gets stomped on by the dysfunctional machine of business, we’re heartbroken from the whole identity-crushing experience.

Who we are, what we believe in, and why we care so deeply about our craft, is at the foundation of what it means to be an engineer.

Rama Akkiraju is a Distinguished Engineer, and Master Inventor at IBM. Rama is presently leading the mission of enabling natural, personalized and compassionate conversations between computers and humans via user modeling at IBM’s Watson division. Specific projects in user modeling domain that she is leading include:  researching and developing technologies to infer people’s personalities, emotions, tone, attitudes and intentions etc. from social media data using linguistic and machine learning techniques. In her career, Rama has worked on agent-based decision support systems, electronic market places, and business process integration technologies including semantic Web services, for which she drove a World-Wide-Web (W3C) standard.

Rama has co-authored 4 book chapters, and over 50 technical papers. Rama has over dozen issued patents and 20+ others pending. She is the recipient of 3 best paper awards in the areas of AI and Operations Research. Rama also received multiple awards and honors at IBM in her professional career.

Rama holds a Masters degree in Computer Science and has received a gold medal from New York University for her MBA.

From Science Fiction to Science Fact: How AI Will Change Our Approach to Building Apps and Leveraging Data

We have entered a new period of computing history — a cognitive era.

For decades, science fiction visionaries have shared their renditions of intelligent machines and computers that could learn and function as humans. Intelligent machines have moved beyond the lore of science fiction; today, they are a reality thanks to breakthroughs in AI and machine learning.

So how will this impact and change the apps that we build and how we leverage new and existing data?

In this interactive session, we’ll explore those questions, and

  • Discuss where AI currently is and where the technology is going
  • Show how pioneering apps and developers around the world are already using it
  • Provide access to sample code and applications that you and your teams can use to understand and explore cognitive computing for yourself

Dr. Olivier Gevaert is an assistant professor of medicine (biomedical informatics) and biomedical data science at the Stanford University School of Medicine. The Gevaert Lab focuses on multi-scale biomedical data fusion focusing on applications in oncology. This involves modeling data at molecular, cellular, and tissue levels using a wide range of different technologies such as sequencing (DNA, RNA) and imaging  (MRI, CT, PET, etc.). The lab develops computational approaches to find relevant patterns in these high dimensional, multi-modal data sets. These machine-learning methods combine elements from statistic and mathematics and apply them on multi-scale data, ranging from molecular biology, to pathology, to radiology.

Thursday Opening: Olivier Gevaert
9am – Room 220A

Deep Learning in Biomedicine: Challenges and Opportunities

Massive amounts of data are being generated in biomedicine ranging from molecular, to cellular, to tissue-scale data. It is now possible to study a patient from multiple angles and scales with multi-modal, multi-scale, high dimensional, and high throughput biomedical data. However, these data are noisy, sometimes parts are missing, and it is unknown what entities are important for “precision medicine,” the concept that medical care has to be designed to optimize treatment of a patient by using the patient’s own data.

In parallel, deep learning has revolutionized fields such as image recognition, natural language processing and, more broadly, machine learning and AI. Now, deep learning is becoming increasingly more popular for analyzing biomedical data. This talk will introduce the types of data in biomedicine, including images, text to numeric data, and the potential opportunities and challenges for modeling this data using deep learning.

Thursday Opening: Brian Kane
9:25am – Room 220A

Personality Is the New Ringtone:
Experiments in AI design

AI design requires a fundamentally new type of design thinking. How can we identify and address the new challenges of designing intelligent and connected devices and experiences for people? In this talk, we’ll discuss what we’ve learned, market opportunities, design trends, methods for prototyping, and new opportunities for innovation — and that Billy Bass Alexa hack.

Brian Kane currently lives and works in Cambridge, Massachusetts. He received a BFA in painting from Rhode Island School of Design in 1987, where he also teaches. His sculpture, interactive, and video work has shown in many museum and gallery exhibitions, and his pioneering real time video sampling techniques was influential to a generation of media artists. He was a founding member of the video art group EBN, and a primary collaborator with Amorphic Robot Works. His latest work “Healing Tool” is a disappearing billboard, and can be see here.

Thursday Closing: Happy Hour with the Java Posse and Atlassian
5pm – Room 220A

Java Posse LIVE Podcast

The Thursday closing keynote will include an exclusive Java Posse reunion with Dick Wall, Chet Haase, Tor Norbye, Joe Nuxoll, and Carl Quinn.


Thanks to our friends at Atlassian for sponsoring the Happy Hour at closing. Grab a beer and a snack at an Atlas Bar as you head into the Closing Keynote!
