Keynote Speakers

Devoxx US includes opening keynotes on Tuesday, Wednesday, and Thursday, and a closing keynote on Thursday.


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.

Tuesday: Janelle Klein

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.


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

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

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: Java Posse

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.
