Brief synopsis of current research:
The objective of my research is to understand the ecological control of growth, mortality and reproductive strategies of fishes. The place and timing of spawning and the use of specific nursery areas are adaptations to ecological conditions that favour survival of the vulnerable early life-history stages. We focus on larvae and juveniles in estuarine and riverine habitats to insure the conservation of habitat critical to the survival of exploited species such as salmon, trout and smelt.

Comments:
Aquatic systems are the dominant ecosytems of our planet. Fish represent over 50% of all known vertebrate species. These ecosystems and the fish species that depend on them are under increasing pressure from humans; habitat destruction, pollution and overfishing. These pressures will only increase as human populations and per-capita consumption continue to grow. As the human population becomes more urban and the planet’s biodiversity continues to erode to support the population centers, mankind is showing signs of evolving a technology-based virtual reality where nature is at best represented as a setting for adventure tourism and at worst in the form of a theme park. Not only is the planet losing biodiversity, human society maybe losing interest in biodiversity. I can think of no career which is as fascinating, rewarding and urgent as that of the biologist. But the challenges will be increasingly difficult in the future. We must not only deepen our understanding of the how and why of life, but we must also become far more vocal and active to make sure that our knowledge penetrates the realm of public awareness and influences public policy.
