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 will lead the Robust, Scalable Sequential Monte Carlo with Application To Urban Air Quality project from April 2020 — 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.
There is currently a vacancy for a postdoctoral research associate within my group — feel free to contact me with informal inquiries.
Some generic teaching information - - applicable to my personal tutees, MSc students and those attending my lectures is available from my teaching page.
Students and Collaborators
Current interests include Monte Carlo methodology, particularly sequential methods together with Bayesian statistics and decision theory more generally.
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.
Current Ph.D. Students:
- Letizia Angeli (co-supevisor Stefan Grosskinsky)
- Susanna Brown (co-supervisor Jere Koskela)
- Francesca Crucinio (co-supervisor Arnaud Doucet)
- James Hodgson (co-supervisor Murray Pollock)
- Lewis Rendell (co-supervisor Anthony Lee)
- Denishrouf Thesingarajah
- Måns Unosson (co-supervisor Bärbel Finkenstädt )
