Harshana Rajakaruna
is a PhD candidate in Mathematical Biology working under the supervision of Dr. Mark Lewis.  He is applying stochastic differential equations to model invasion risk of marine copepod species.  His work involves incorporating stochastic processes such as propagule pressure, temperature, and demography into modeling and improvising predictability of species invasiveness and habitat invasibility.  He is fascinated by the numbers of change, transient probability, and neutral theories of biodiversity.
Harshana obtained his Advanced Level Diploma and BSc in mathematics and physics, MSc in natural resource management (and environmental economics) from the University of Peradeniya, and MSc in statistical and computer simulation modeling (application to fish stock assessment) from Memorial University of Newfoundland.  He has worked for the International Union for Conservation of Nature (IUCN) as a Senior Programme Officer, Informatics (Information Systems) as the Manager (Kandy), and the Department of Electronic and Telecommunication Engineering, University of Moratuwa as an Instructor (Physics).

Harshana enjoys playing classical guitar, improvisations on the piano, impressionist painting and sculpture, writing poetry, and meditation.  He is an ardent reader of existentialism, quantum reality, and Buddhist philosophy.
