get paranoid about me watching their screen.

Well, there's only a handful of students in my lab to begin with. So all hands on deck is like, what, seven or eight PhD students plus us. Typically speaking, the projects are a little bit smaller just because we've got multiple projects going on. And so people are partitioning their attention and work energy at different things.

Adversarial machine learning is a shorthand for this interesting research area at the intersection of computer security and machine learning. anything to do with attacks, defenses, privacy concerns, surveillance, all these subtopics as related to machine learning and AI. That's what I've been working on mostly for the last decade.

For more than two years, we've been focused on how the misuse and abuse of these AI tools can harm real people and trying to build research tools and technology tools to try to reduce some of that harm. To protect regular citizens and, in particular, human creatives like artists and writers.

So that's from my D&D days. It's a fun little project. We had done prior work in ultrasonics and modulation effects when you have different microphones and how they react to different frequencies of sound. One of the effects that people have been observing is that you can make microphones vibrate in a frequency that they don't want to.

We figured out that we could build a set of little transducers. You can imagine a fat bracelet, sort of like cyberpunk kind of thing with, I think, 24 or 12. I forget the exact number. Little transducers that are hooked onto the bracelet like gemstones.

Well, hey, you got to do what you got to do, and hopefully other people will make it much smaller, right? We're not in the production business. What it does is basically it radiates a carefully tuned pair of ultrasonic pulses in such a way that commodity microphones anywhere within reach will, against their will, begin to vibrate at a normal audible frequency.

They basically generate the sound that's necessary to jam themselves.
