<h2>Research interests</h2>
I am generally interested in computational and mathematical neuroscience with an emphasis on stochastic dynamics. Specifically, I work on these topics:
<br>
<ul>
<img src="images/bm_met.png" align=right style="width:210px;height:135px;">
<li><p><b>Dynamics and computation</b> in spiking neural networks</p></li>
<li><p><b>First-passage problems</b> (picture shows mean exit time for a Brownian motion from a disk with small absorbing holes of different sizes- the mean exit time decreases near the absorbing holes)</p></li>
<li><p><b>Neuronal adaptation</b> with varying timescales</p></li>
<li><b>Correlations and dynamics</b> in non-renewal stochastic neuron models</li>
<li> <p><b>Numerical solution</b> of Fokker-Planck and backward Kolmogorov PDEs by finite-element methods</p></li>
<li><p><b>Analysis of neural data </b></li>
<li><p><b>Artifical neural networks</b> and deep learning.</p></li>
</ul>
