Dr Tom Cresswell 

Dr Tom Cresswell is an environmental research scientist with a passion for understanding how humans impact our environment.  He studies how pollution interacts with living organisms in freshwaters
through coastal areas.  Tom’s position at ANSTO allows him
to use nuclear techniques (radioisotope tracers) very precisely
study how quickly pollutants get into a living organism, where it
goes within the tissues and then how quickly they are removed
from the tissues if the source of pollution is removed or the
animal moves to cleaner waters.  This helps us understand what
kind of effect the pollution will have on the organism so that we
can better manage our precious aquatic ecosystems.  Tom is
currently working with the offshore petroleum industry to assist in providing a scientific basis for their decommissioning planning.
