I enjoy sharing the lessons I have learned over my decades on the front-lines of the Internet. Having built security organizations from the ground up at three major companies, I have seen and responded to safety and security threats in every context you can imagine.

I have keynoted many safety and security conferences, on topics ranging from online safety for children to leveraging machine learning to detect fraud and abuse to promoting and developing a diverse team. I’ve also testified twice before the United States Congress, and appeared before government and academic bodies in Australia, India, China, and across Europe.
