06/20/25: TypeScript Types Can Run DOOM with Dimitri Mitropoulos

Dimitri Mitropoulos is a Michigan-based typescript dev, linguist, and classicist who joined us to talk about his completely unhinged, odyssean, and frankly just unwise project to get DOOM running completely within Typescript's type system. Someone give the dude a PhD, please.

Jenna DiVincenzo is an Assistant Professor in the Elmore Family School of Electrical and Computer Engineering @ Purdue University. She is broadly interested in research spanning software verification, programming languages, and software engineering, especially research aimed at making verification techniques and programming languages more usable and scalable. Today Jenna joined us to talk about her broad research program in gradual verification. This was a really interesting talk with great Q&A and we hope you enjoy it as much as we did!

Prashant Anantharaman is a long-time BCC group member and has presented as both a solo researcher and a panelist to prior events. Today he joined us to present some of his work with NARF, to appear at IEEE S&P, on generating grammars for fuzzing using LLMs. This is a super exciting new frontier for LLMs and LangSec generally and his talk was wonderful.

Ramit Das is a formal verification engineer at Intel and an avid Boston Computation Club group member. Ramit and I have been speaking for ages about formal methods, exchanging papers, etc. and today he finally agreed to come give a talk to the group about his area of expertise -- descriptive complexity. This was a really fun talk and an excellent introduction for anyone looking to get their feet wet with complexity theory, some language theory, and even a smidgeon of model theory and underpinnings of abstract interpretation. It was really fun and we can't wait to host another talk by Ramit sometime in the future!

Today Marc Denecker joined us to present How and Why to extend First Order Logic for Knowledge-Based Systems. This presentation provided the setup for a follow-on that Marc's student Simon Vandevelde is set to give on IDP-Z3, a formal reasoning machine that Marc and Simon have built. This was a really interesting talk touching on a variety of forms for formal logic, decision procedures, and industrial use-cases thereof, potentially with profound implications for the future and realizability of so-called AGI.

Today Daniel Melcer joined us to present Constrained Decoding for Code Language Models via Efficient Left and Right Quotienting of Context-Sensitive Grammars (https://arxiv.org/pdf/2402.17988). This is work he completed while at Amazon, and it's a really interesting project around how to constrain, guide, and check language models such that they generate valid code within a given context. We really appreciate that Daniel took the time to talk to us and hope you like the talk as much as we did!

Michael H. Borkowski is an Assistant Professor of Practice in the Department of Computer Science at Purdue University. Before joining Purdue, he earned his Ph.D. from the Department of Computer Science and Engineering at UC San Diego, where he was affiliated with the ProgSys Group. Today Michael joined us to discuss LiquidHaskell, a very cool project that incorporates a kind of refinement types, with SMT-based proofs, into Haskell. This was a really compelling talk and we hope you enjoy it as much as we did!

Today Brook Santangelo and John Sterrett

Gaspard Baye is a Cyber AI Ph.D. Candidate at the University of Massachusetts Dartmouth, where he researches AI-driven offensive and defensive security applications. Today Gaspard joined us to present "Hacking GenAI with LLM Red Teaming and Beyond" based on his recent DefCon talk. This was a really fun event with a great Q&A. Thanks to Jacob from the Trust Lab for hosting!

Navid Hashemi recently defended his PhD at USC and is about to begin a post-doc at Vanderbilt.  His research focuses on the intersection of Artificial Intelligence and Temporal Logics, with applications in Formal Verification of Learning Enabled Systems and Neurosymbolic Reinforcement Learning.  Today Navid joined us for a really exciting presentation about his work on metrizable logics for reinforcement learning, and a technique for verification thereof based on the over-approximation of reachable sets using ReLU.
