  Keynote: Making signal out of noise: a guide to effective research skills while maintaining mental health in an ADHD world
 Ionescu & Shafir
  Galavanting around the world, publishing endless blog series - many unfinished - and dropping research on eight different topics in a single year. All while maintaining double lives, one as a circus artist, the other as a corporate executive at a 2000+ person public company listed on the NASDAQ. In their spare time - teaching training courses at conferences and private organizations worldwide. Hobbies: one is a pastry chef and the other an author.

In this amusing-yet-serious talk, Yarden Shafir and Alex Ionescu, long time collaborators on Windows Internals research and development, share the trials and tribulations of how they do research, pick topics, come up with use cases, and publish interesting and broken behaviors in the Windows kernel, all while teaching training courses and maintaining their other identities. Filled with fun anecdotes, the duo hope to share insight into (in)effective time management, topic selection, collaboration techniques, reverse engineering tips, making and breaking boundaries, and how coping with ADHD adds its own unique challenges -- and delightful surprises.

If you're struggling to find your next research topic, infosec passion, or simply coping with today's world, we hope all attendees will walk away with at least one important lesson, tool, advice, or at the very least, chuckle.
  Alex Ionescu is the Vice President of Endpoint Engineering and Founding Chief Architect at CrowdStrike, Inc. Alex is a world-class security architect and consultant expert in low-level system software, kernel development, security training, and reverse engineering. He is coauthor of the last three editions of the Windows Internals series, along with Andrea Allievi, Mark Russinovich, and David Solomon. His work has led to the fixing of many critical kernel vulnerabilities, as well as dozens of non-security bugs.

Previously, Alex was the lead kernel developer for ReactOS, an open source Windows clone written from scratch, for which he wrote most of the Windows NT-based subsystems. During his studies in Computer Science, Alex worked at Apple on the iOS kernel, boot loader, and drivers on the original core platform team behind the iPhone, iPad and AppleTV. Alex is also the founder of Winsider Seminars & Solutions Inc., a company that specializes in low- level system software, reverse engineering and security trainings for various institutions. In the last three years, he has also contributed to patches and development in two major commercially used operating system kernels.

Yarden Shafir started dancing at the age of 7, and later joined a rhythmic gymnastics team and competed during her teenage years. After her military service, she practiced pole dancing and fell in love with acrobatics. Today she performs aerial arts for the circus, trains whenever possible, and teaches lyra and silks in Israel, while also having a rich background of Windows Internals research originally at Sentinel One, followed by her current role as a Software Engineer at CrowdStrike working on various EDR capabilities and EPP features.
