My research program is in two areas: capture-recapture experiments and statistical consulting in environmental impact studies. It is motivated by real problems encountered by ecologists and health researchers.

My current research projects in **ecology** are in the estimating of animal abundance, survival, movement and related
parameters using mark-recapture methods. Mark-recapture involves
the marking of animals (e.g. rings on bird legs; tags on fish; radio collars on large mammals) and
then releasing these animals back to their population.
Subsequent resightings or recaptures of the marked and unmarked animals allow us
to estimate the survival rate, the population size, and the movement rates of the animals.

My **health-related** research interests are in capture-recapture methods which
are known in epidemiological studies as multi-list methods. These are used
to estimate the size of populations where incomplete lists are kept of
members. For example, how many injecting drug users (IDU) are there in
Vancouver? Various social agencies have (incomplete) lists of IDUs. Based on
the patterns how which names appears on multiple lists, an estimate of the
number of people not appearing on any list can be obtained. As expected,
there are serious problems of listing errors (e.g. is J.Smith the same as
J.Smithe?) and the 'probability of capture' on each of the list is very
heterogeneous among sub-populations.

My **environmental impact** research interests lie in designing and analysing
environmental impact studies. This is motivated by my extensive consulting
work with Environmental Consulting companies.
