Stanford & Google DeepMind — San Francisco, CA

I am a student at Stanford University and student researcher at Google DeepMind. Advised by Prof. Hany Farid and Prof. Maneesh Agrawala, I work at the intersection of AI, computer vision, and media forensics. My goal is to build AI systems that are inherently trustworthy and interpretable.

Uncovering Conceptual Blindspots in Generative Image Models Using Sparse Autoencoders

Bohacek M.*, Fel T.*, Agrawala M., Lubana E. Under Review.
Project Paper Code Weights — Method for identifying blindspots in T2I models: concepts that the model was trained on but can’t generate.

Human Action CLIPs: Detecting AI-generated Human Motion

Bohacek M. & Farid H. IJCAI-W 2025.
Paper Dataset — This paper proposes a method for distinguishing real and fake (T2V) video using multi-modal semantic embeddings, evaluated on DeepAction, a new dataset of real and AI-generated human motion.

The DeepSpeak Dataset

Barrington S., Bohacek M., and Farid H. ArXiv, abs/2408.05366.
Paper Dataset — This paper introduces DeepSpeak, a large-scale dataset of real and deepfake footage designed to support research on detecting state-of-the-art face-swap and lip-sync deepfakes.

Nepotistically Trained Generative-AI Models Collapse

Bohacek M. & Farid H. ICLR-W 2025.
Paper — This paper demonstrates how some generative AI models, when retrained on their own outputs, produce distorted images and struggle to recover even after retraining on real data.

GenAI Confessions: Black-box Membership Inference for Generative Image Models

Bohacek M. & Farid H. ICCV-W 2025.
Paper Dataset — A method to determine whether a generative AI model was trained on specific images.

Synthetic Human Action Video Data Generation with Pose Transfer

Knapp V. & Bohacek M. CVPR-W 2025.
Project Paper Code Data — We show that synthetic data of human motion improves performance of action classification and understanding.
