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 the benefits and risks of artificial intelligence to 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.
