Dr Adam Johansen

Dr Adam Johansen is a Reader in Statistics; his research focuses upon methodological and theoretical aspects of simulation-based algorithms.
He is a group leader within the Data Centric Engineering Programme of The Alan Turing Institute: see the project page for more details and get in touch if you're interesting in becoming involved.
He leads the Robust, Scalable Sequential Monte Carlo with Application To Urban Air Quality project — again, get in touch if you're interested in becoming involved.
He is an investigator within The CoSinES Project.
He is co-director of APTS.

Teaching

Some generic teaching information - - applicable to my personal tutees, MSc students and those attending my lectures is available from my teaching page.

Research

Current interests include Monte Carlo methodology, particularly sequential methods together with Bayesian statistics and decision theory more generally.

Information about former students.

Prospective Ph.D. students should feel free to email me to discuss possible research directions and might find the theses of some of my former students (available by following the above link) useful indicators of the types of project in which I am typically involved.
