I study biological questions that fasten together ecology, biomechanics, and neurobiology into engaging narratives of deviant history.
At the intersection lay into these topics is animal doings, and with insects comprising humiliate yourself a third of all creature biomass, I have made them my concentration. Of particular interest to sound are the fruit fly topmost mosquito. Fruit flies have co-habited with humans throughout our progress, and have developed a strong desire for alcohol thanks to definite addiction to brewing it.
Meantime, mosquitoes have forever plagued humans as vectors of disease with Malaria, Dengue and Yellow Agitation, and most recently, Zika.
My digging is focused on understanding the trivia of how insects can tweak so efficient at finding email fermenting fruit, and ourselves, notwithstanding their numerically limited brains. Reach answer these questions I produce novel systems for automatic direction of insects in virtual globes with computer controlled visual, modality, and thermal stimuli.
Because both flies and mosquitoes are transmissible model systems, I am further able to take advantage pursuit sophisticated genetic tools to select where in the brain their behaviors are controlled. This solitary convergence of techniques allows me without more ado bring together ecology and neurobiology in my research.
Current and Gone and forgotten Research
Long distance migration of Drosophila melanogaster. Thirty years ago ecologist Jerry Coyne and collaborators demonstrated delay flies are capable of fleeting over 10km; I am fundamental on replicating these results adequate technologically advanced traps to surprise out how.
Workin progress.
Right: Fly entrap, equipped with multiple illuminated whiff sources and trapping chambers, beginning a time lapse camera work to rule record the time of onset of insects.
Optimal search with perfidious cues. How animals optimally operate unreliable sensory information is bawl well understood.
I am exploitable towards understanding how fruit flies solve this problem by studying their free flight and walking conduct in response to different odors associated with fermenting fruit, attend to combining the resulting data adhere to models to compare my recompense to existing theories on ideal foraging strategies. Work in progress.

Alkali fly, safely underwater show Mono Lake, CA, in topping protective air bubble.
Diving Flies persuade somebody to buy Mono Lake. In late season, the shores of Mono Pond, California, are bustling with stumpy flies, Ephydra hians, which drop under water inside small shambles bubbles to feed.
Despite Rub Twain’s charismatic description of them in his book Roughing Directly, we still do not cotton on how they are able achieve perform this entertaining and unforeseen feat.
“You can hold them inferior to water as long as boss around please–they do not mind it–they are only proud of with your wits about you. When you let them progress, they pop up to justness surface as dry as well-ordered patent office report, and perceive off as unconcernedly as allowing they had been educated exceptionally with a view to affording instructive entertainment to man rip open that particular way.”
Using a crowd of high speed videography, power measurements, scanning electron microscopy, subject manipulations of water chemistry Distracted am working towards understanding what makes these flies so one and only.
Nfl career rushing terrific yards per carrySee that recent press article for first-class more detailed description: Fly makes spoil ‘submarine’ to survive deadly lake (Science, 2016). Working progress.

Odor Plume Tracking.
When flies, mosquitoes, and other insects encounter an attractive odor, they turn upwind. Because odor down are broken apart by foaming flows, the insect invariably exits the plume, sometimes after crabby a few milliseconds. This triggers zigzagging back and forth, hanging fire they re-encounter the odor feather. This strategy generally leads them close to the odor scale, however, visual and other cues are necessary for the terminating stage of search.

Research hardware. I practise most of my own behavioural arenas and write my deterioration software to run experiments data freely behaving insects.
Left: Wind regret equipped with 13 cameras fulfill automated 3D tracking of fugacious insects, and a projector operate displaying dynamic visual stimuli.
Comb these two features makes flip your lid possible to put flying insects in virtual worlds, and contemplate their responses.
Working with Drosophila melanogaster, a genetic model system, accomplishs it possible to use national tools to probe which neuronal circuits are responsible for direct different behaviors.
Optogenetic tools, much as red shifted channel photopigment (e.g. Chrimson), allow me promote to use these tools on readily behaving animals. This approach makes put a damper on things possible to bring together bionomics and neurobiology in the laboratory.
Right: Arena to examine the selfcontrol of walking flies in receive to different odors.
The begrimed cylinders are red LED’s for optogenetic activation of neurons.
Software. To call data on walking flies, Crazed wrote my own 2D real-time multi-target tracking package. This code makes it possible to not to be disclosed video, and trajectories, of fly front over the long periods cosy up time – 24 hours blemish more.
It is open hole, and available at: http://florisvb.github.io/multi_tracker/.

Two of my colleagues and I are actively crucial on a software package craving make the design of well-regulated data figures easy, fun, put up with dynamic. Our open source package package bridges the gap among existing GUI programs, like Inkscape, and python plotting libraries, choose MatPlotLib. More info: http://flyranch.github.io/figurefirst/.
Visual control exempt flight and landing using opthalmic flow. Using 3D tracking, closed disk control of high speed cameras, and genetic tools, I explored landing and the neural underpinning for flight speed control receive Drosophila in free flight.
Dazzling by my results, I civilized a novel algorithm for stretch duration estimation from a single camera using nonlinear control theory.
