Tom Bertalan

I am a Postdoctoral Fellow in the Chemical and Biomolecular Engineering department at Johns Hopkins University. I received my PhD from Princeton University's department of Chemical and Biological Engineering, with a Graduate Certificate in Computational and Information Science. Before working at JHU, I was a Postdoctoral Associate in the MAE department at MIT.

My research interests are in data mining, dimensionality reduction, and system identification (using neural networks) for high-dimensional dynamical systems, with applications in robotic perception and planning, and computational neuroscience.

Visual Scene Grammars

Foundation models can analyze and generate both images and (noisy) grammars. Let's use that to do some visual scene understanding.

Robotics Simulators

Mostly about using Farm Simulator, GTA V, and other games for training both perception and control systems.


Build an Ackermann robot with RGBD as its primary sense.

Equal Space

Nature Comm. 2022. Use nonlinear manifold learning to discover automatically both the true dimensionality and the underlying spatial coordinates that define a high-dimensional simulation trajectory.

Local Neural Text-to-Speech App

A one-pyfile PyTorch+tk GUI for local neural text-to-speech synthesis.

ANOVA and PCE for Biological Neural Networks

Use ANOVA to perform integrals for polynomial chaos expansions.

Representation Learning

PNAS 2020. Unsupervised learning methods to transform data into a form that's somehow more useful.

Iterative ANNs

Neural networks build on various numerical iterative algorithms.

Hamiltonian Neural Networks

Learn dynamics with constrained quantities.


Build a differential-drive robot with LIDAR as its primary sense.

Project Opener Menu

A little TK menu for quickly getting to my project directories.

GPT3 for Seminar Announcements

Use OpenAI's API to generate ics files from email text.

Next Task Decider

Process task list and decide what I should do next.

Cat Wrangler

A feline surveillance bot using the guts of an iRobot Braava.

Boston AV Group Robocar

Teach a one-week workshop to high school students on building and programming a small autonomous car.

Hierarchy Formation

Simulate the formation of dominance hierarchies through social combat.

Circadian Rhythms

Simulate circadian rhythms in the suprachiasmatic nucleus of the hypothalamus.
