Individual and long-term analysis of honey bee behavior

We tagged and tracked the lifetime behavior of 13,000+ honeybees using the Beesbook barcode tracking system, to understand how bees differ in their lifetime behavioral patterns, how male reproductive drones synchronize behavior in the nest, and how the colony responds to environmental perturbations such as heat stress. With the labs of Michael Smith, Iain Couzin, and Tim Landgraf.

Social behavior of rodent groups

We are are analyzing the social behavior of rodent groups and the effect of group and environmental perturbations. With Ahmed El Hady and Máté Nagy.

Foraging behavior from individual to collective

We used techniques from neuroscience to model foraging behavior, with a goal of bridging concepts between disciplines.
Extensions consider optimal strategies and exchange of information in social foraging groups. Current work is analyzing social behavior of rats and designing experiments using rats and locusts. With Ahmed El Hady and Zachary Kilpatrick

Collective motion of C. elegans nematode worms

Different mutants of the model organism C. elegans show very different collective behavior patterns. We are using tracking and quantitative methods to describe these different patterns, and simulations to represent different mutants as well as mixed groups of worms.

Parasitism and movement of guppies

This project asks how parasites affects both the individual and collective behavior of guppy fish. Experiments include individual flow-tank testing, and collective motion of groups. With Iain Couzin and Angela Albi.

Comparing collective systems

As part of an interdisciplinary project with Medhavi Vishwakarma and Michael Smith, we asked how different collective systems — such as honey bees and epithelial cells — coordinate their behavior to function as a group, and developed a conceptual framework that can be used to compare different collective systems.

Genetic control of collective behavior in zebrafish

Working with Mark Fishman, we analyzed data of a large-scale genetic screen for social behavior of zebrafish. By comparing 90 different genetic mutants plus wild type fish, we identified mutant lines that differ in behavior.

Parasitism and motion of stickleback fish

With Jolle Jolles, I used motion modeling to understand how parasites affect the pair-swimming motion of stickleback fish, to show that a passive mechanism – speed differences – can explain dominant leader-follower motion trends.

Motion and foraging behavior of desert harvester ants

With Mark Goldman and Deborah Gordon, I used models from physics and neuroscience to understand how harvester ants use interactions to regulate foraging behavior and organize spatially in the nest.

Electroactive polymers and rubber elasticity

In my PhD work with Nakhiah Goulbourne, I developed models of electroactive polymers and rubber elasticity, and used molecular dynamics simulations to examine how microscopic configurations lead to macroscopic material properties.
