# Tom Bertalan

I am a fifth-year graduate student soon to receive my PhD from Princeton University's department of Chemical and Biological Engineering, with a Graduate Certificate in Computational and Information Science.

My research interests are in data mining and dimensionality reduction for high-dimensional dynamical systems, with applications in robotic perception and planning, and computational neuroscience.

## Robotics

A differential-drive robot with LIDAR as its primary sense..

## Equal Space

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

## Circadian Rhythms

Simulation of circadian rhythms in the suprachiasmatic nucleus of the hypothalamus.

## ANOVA and PCE for Biological Neural Networks

Use ANOVA to perform integrals for polynomial chaos expansions.

## Debriefing Neural Networks for Nonlinear Dynamics

Using neural networks as models for process dynamics, and using manifold learning to understand and simplify the fitted networks.

## Next Task Decider

Process task list and decide what I should do next.

## Hierarchy Formation

Simulation of the formation of dominance hierarchies through social combat.

## Diffusing Neuromodulator

Include a diffusing neuromodulatory signal in a simulation of a biological neural network.
