Research
Click here to see some recent activity (talks/discussions) of the Computational Statistics Group of the Dept. of Statistical Science. Contact me if you are interested to present your work to the group.
Some of my research interests:
-
Monte Carlo methodology for inference and optimisation problems:
- Sequential Monte Carlo
- Markov Chain Monte Carlo
- Stochastic optimal control, fully and partially observed Markov Decision
Processes.
- Non-linear filtering, parameter inference for state space models, Hidden Markov
models.
- Rare events estimation
- Some applications:
- data assimilation: inverse problems for the Navier-Stokes equation
- electrical power scheduling from renewable sources
- air traffic management: conflict detection and resolution for avionics
- estimation and inference for rare or hazardous processes
- sensor management for target tracking and trajectory planning problems
- distributed inference for sensor networks
- risk sensitive portfolio optimisation
