I have been a member of the Buzsáki lab since October 2004, learning and performing multi-tetrode, and silicon microprobe recordings in the rat hippocampus during behavior. I am interested in how representations of spatial information and episodic memory can be altered by plasticity in the CA1 and CA3 hippocampal network. I record from large numbers of neurons simultaneously, in good recordings finding ~20-30 active place-cells in a given environment. By making modifications in the environment, I look for changes in the firing relationships (such as cross-correlation) of active neurons. This is work in progress.
Recently, I have also become interested in sequences during hippocampal sharp-wave ripples. Sequences of place-cells that are activated during a run through an environment are reactivated in a time-compressed manner during sharp-wave ripples. The ordering during these reactivation events reflects the ordering observed during running, in forward and in reverse, depending on if the animal is about to start running, or has just finished running! We created some abstract artwork to illustrate our findings. Our manuscript on this phenomena is available online at Nature Neuroscience. Now, I am working to understand the underlying mechanisms behind these ordered events.
Previous to joining the Buzsáki lab, I worked with Christof Koch and other colleagues to investigate the characteristics of intrinsic noise in neurons.

I spent a summer traveling across India and Sri Lanka.
Plus a winter vacation biking through Vietnam and Cambodia. My camera was stolen in Phnom Penh, so unfortunately, many pictures did not survive.
One of my favorite books, Ecclesiastes, can be found online.

I ran my first half-marathon in June 2007, in Fairfield, CT. I came
in at just under 2 hours (1:58:48) finishing 937 out of 1837 runners. I
recently ran my second half-marathon in the Bronx
in February 2008, seconds under 2 hours (1:59:55), finishing 1861 out of 3261.
We have fans of both clockwise and
counter-clockwise in our lab...
